+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Datasette's own test suite uses a SQLite database with tables that exercise features such as compound primary keys, foreign keys, sortable columns, facets, full-text search and binary data.
+
+You can use those same tables in your plugin tests using the ``populate_fixture_database(conn)`` helper in ``datasette.fixtures``:

+
+This hook allows plugins to add extra results to Datasette's ``/`` jump menu, which is powered by the ``/-/jump`` JSON endpoint.
+
+Return a ``datasette.jump.JumpSQL`` object, or a list of ``JumpSQL`` objects. Each ``JumpSQL`` object wraps a SQL query to be combined with Datasette's own databases, tables, views and canned query results.
+
+The SQL query must return these columns:
+
+``type``
+    A short type string for the result, for example ``"app"`` or ``"dashboard"``.
+
+``label``
+    The stable name for the result. This is returned as ``name`` in the JSON API and is used for sorting.
+
+``description``
+    A short description shown above the item in the jump menu.
+
+``url``
+    The URL to navigate to when the item is selected.
+
+``database_name``
+    The database name for Datasette resources, or ``NULL`` for custom plugin results.
+
+``resource_name``
+    The table, view or query name for Datasette resources, or ``NULL`` for custom plugin results.
+
+``search_text``
+    Text that should be searched by the ``?q=`` parameter.
+
+``sort_key``
+    A numeric value used to order results.
+
+``source``
+    A string identifying the plugin that supplied the result.
+
+If the SQL query also returns a ``display_name`` column, set ``has_display_name=True`` on the ``JumpSQL`` object. Datasette will return that value as ``display_name`` in the JSON API, and the jump menu will show it as the primary readable label with ``name`` shown underneath.
+
+This example adds a "Plugin dashboard" result for signed-in users:
+
+.. code-block:: python
+
+    from datasette import hookimpl
+    from datasette.jump import JumpSQL
+
+
+    @hookimpl
+    def jump_items_sql(actor):
+        if not actor:
+            return None
+        return JumpSQL(
+            sql="""
+            SELECT
+                'dashboard' AS type,
+                'plugin-dashboard' AS label,
+                'Dashboard' AS description,
+                '/-/plugin-dashboard' AS url,
+                NULL AS database_name,
+                NULL AS resource_name,
+                'plugin dashboard' AS search_text,
+                80 AS sort_key,
+                'my-plugin' AS source,
+                'Plugin dashboard' AS display_name
+            """,
+            has_display_name=True,
+        )
+
+Use ``params=`` to pass SQL parameters. Datasette will automatically namespace those parameters before combining SQL fragments from different plugins.
+
+.. _plugin_hook_jump_start:
+
+jump_start(datasette, actor, request)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+``datasette`` - :ref:`internals_datasette`
+    You can use this to access plugin configuration options via ``datasette.plugin_config(your_plugin_name)``, or to execute SQL queries.
+
+``actor`` - dictionary or None
+    The currently authenticated :ref:`actor <authentication_actor>`.
+
+``request`` - :ref:`internals_request` or None
+    The current HTTP request. This can be ``None`` if the request object is not available.
+
+This hook allows plugins to add custom HTML to the default blank state of Datasette's ``/`` jump menu, before the user starts typing a search.
+
+The hook can return a string, a ``markupsafe.Markup`` object, or an awaitable function that returns either of those. Return ``None`` to add nothing.
+
+This example shows a link for starting a new chat if the user is signed in:
+
+.. code-block:: python
+
+    from datasette import hookimpl
+    from markupsafe import Markup
+
+
+    @hookimpl
+    def jump_start(actor):
+        if not actor:
+            return None
+        return Markup(
+            '<p><a href="/-/agent/new">Start a new chat</a></p>'
+        )

 Use ``params=`` to pass SQL parameters. Datasette will automatically namespace those parameters before combining SQL fragments from different plugins.
 
+``JumpSQL.menu_item(...)`` is a shortcut for adding a single jump menu item that is not backed by a resource in Datasette's internal catalog tables. It returns ``NULL`` for ``database_name`` and ``resource_name`` and accepts the keyword arguments shown above.

 - Fixed a Safari bug with the table search mechanism triggered by pressing ``/``. (:issue:`2724`)
 - New "Jump to..." menu item, always visible, for triggering the previously undocumented ``/`` menu. (:issue:`2725`)
 - The ``/`` jump-to search interface now covers databases, views, canned queries and plugin-provided items in addition to tables. The endpoint backing it has been renamed from ``/-/tables`` to ``/-/jump``.
-- New :ref:`plugin_hook_jump_items_sql` plugin hook, allowing plugins to contribute additional items to the jump-to menu by returning SQL. ``JumpSQL`` queries run against Datasette's internal database by default, or can target another database using the optional ``database=`` argument. Datasette groups these queries by database and executes one ``UNION ALL`` query for each database.

-- Jump menu results now show their ``type`` as a category label, and can show optional longer ``description`` text for individual results.
 - Debug menu links now appear in the jump-to menu instead of the top-right app menu, with descriptions for each debug item.
 - New documented :ref:`datasette.fixtures.populate_fixture_database(conn) <datasette_fixtures_populate_fixture_database>` helper for creating the fixture database tables used by Datasette's own tests, intended for plugin test suites.

 Changelog

-.. _unreleased:

-Unreleased
-----------
+1.0a30 (2026-05-24)
+-------------------
+
+The "Jump to" menu, activated by hitting ``/`` or through the application menu, can now be extended by plugins.
 
-- Dropped Janus as a dependency, previously used to manage the write queue. This should not have any impact on plugin developers or end-users. (:issue:`1752`)
-- Fixed a bug where stale tables and other related resources were not removed from ``catalog_*`` tables when a database was removed. (:issue:`2723`)
-- Fixed a Safari bug with the table search mechanism triggered by pressing ``/``. (:issue:`2724`)
 - New "Jump to..." menu item, always visible, for triggering the previously undocumented ``/`` menu. (:issue:`2725`)
 - The ``/`` jump-to search interface now covers databases, views, canned queries and plugin-provided items in addition to tables. The endpoint backing it has been renamed from ``/-/tables`` to ``/-/jump``.
 - New :ref:`plugin_hook_jump_items_sql` plugin hook, allowing plugins to contribute additional items to the jump-to menu by returning SQL. ``JumpSQL`` queries run against Datasette's internal database by default, or can target another database using the optional ``database=`` argument.
 - ``datasette.jump.JumpSQL.menu_item()`` is a shortcut for adding individual jump menu items that are not backed by resources in the internal catalog.
 - New :ref:`javascript_plugins_makeJumpSections` JavaScript plugin hook, allowing plugins to add custom blank-state sections to the jump-to menu before the user has typed a query.
 - Debug menu links now appear in the jump-to menu instead of the top-right app menu, with descriptions for each debug item.

+- Fixed a bug where stale tables and other related resources were not removed from ``catalog_*`` tables when a database was removed. (:issue:`2723`)
 - New documented :ref:`datasette.fixtures.populate_fixture_database(conn) <datasette_fixtures_populate_fixture_database>` helper for creating the fixture database tables used by Datasette's own tests, intended for plugin test suites.
+- Keyboard accessibility and ARIA roles for actions menus, thanks `pintaste <https://github.com/pintaste>`__. (:pr:`2727`)

Subject: [PATCH 040/137] Database.analyze_sql(sql) method

Experimental, we may need this for the upcoming canned query
work so that we can tell if a user should be able to save
a writable canned query by confirming they have the right
permissions to update the affected tables.

+# Queries in the internal database
+
+Plan for <https://github.com/simonw/datasette/issues/2735>.
+
+## Goal
+
+Move named query definitions into Datasette's internal database, so hundreds or thousands of queries can be listed, searched, permission-filtered, managed, and executed efficiently.
+
+Terminology change: these are now "queries", not "canned queries". Legacy code and documentation can mention the old name only when describing compatibility or migration.
+
+## Decisions so far
+
+- Internal table name: `queries`.
+- Query definitions should use real columns, not a JSON blob for all options.
+- Query parameter names live in a `parameters` text column as a JSON array. No default values for parameters in this pass.
+- No `queries_database_published_idx` index.
+- User-created queries require `execute-sql` and `insert-query` on the database. Writable queries additionally require matching table write permissions discovered by `Database.analyze_sql()`.
+- `publish-query` is the permission for creating or updating a query so users without `execute-sql` can execute it.
+- Add `update-query` and `delete-query`, so administrators can manage queries created by other users.
+- Remove the old `canned_queries()` hook from core. If we want compatibility later, build a separate `datasette-old-canned-queries` plugin.
+- Writable user-created queries can be supported using `Database.analyze_sql()`, provided we fail closed when analysis cannot prove the required permissions.
+
+## Current shape
+
+- Query definitions currently come from `datasette.yaml` or the `canned_queries()` plugin hook.
+- `Datasette.get_canned_queries(database_name, actor)` calls that hook every time it needs query definitions.
+- `QueryResource.resources_sql()` currently enumerates databases and calls the hook for each one, because permissions and `/-/jump` need query resources.
+- Query pages execute if the actor has `view-query` for `QueryResource(database, query)`.
+- Arbitrary SQL executes if the actor has `execute-sql` for `DatabaseResource(database)`.
+
+The main performance and architecture win is making query resource enumeration a direct SQL query against the internal database.
+
+## Proposed internal schema
+
+Start with one `queries` table.
+
+```sql
+CREATE TABLE IF NOT EXISTS queries (
+    database_name TEXT NOT NULL,
+    name TEXT NOT NULL,
+    sql TEXT NOT NULL,
+    title TEXT,
+    description TEXT,
+    description_html TEXT,
+    hide_sql INTEGER NOT NULL DEFAULT 0 CHECK (hide_sql IN (0, 1)),
+    fragment TEXT,
+    parameters TEXT NOT NULL DEFAULT '[]',
+    is_write INTEGER NOT NULL DEFAULT 0 CHECK (is_write IN (0, 1)),
+    published INTEGER NOT NULL DEFAULT 0 CHECK (published IN (0, 1)),
+    source TEXT NOT NULL DEFAULT 'user',
+    owner_id TEXT,
+    on_success_message TEXT,
+    on_success_message_sql TEXT,
+    on_success_redirect TEXT,
+    on_error_message TEXT,
+    on_error_redirect TEXT,
+    created_at TEXT NOT NULL DEFAULT CURRENT_TIMESTAMP,
+    updated_at TEXT NOT NULL DEFAULT CURRENT_TIMESTAMP,
+    PRIMARY KEY (database_name, name),
+    CHECK (is_write = 0 OR published = 0)
+);
+
+CREATE INDEX IF NOT EXISTS queries_owner_idx
+    ON queries(owner_id);
+```
+
+Column notes:
+
+- `database_name`, `name`, and `sql` are the routing and execution core.
+- Display fields become columns: `title`, `description`, `description_html`, `hide_sql`, and `fragment`.
+- `parameters` is a JSON array of parameter names, stored as text. This preserves explicit parameter order, but does not support labels or default values.
+- Existing writable query behavior gets columns too: `is_write`, success/error messages, success/error redirects, and `on_success_message_sql`.
+- `published` only applies to read-only queries. A writable query can still be public through explicit `view-query` permissions, but the "publish for users without execute-sql" shortcut should be read-only.
+- `source` distinguishes `user`, `config`, and `plugin` rows.
+- `owner_id` is the actor id for user-created rows. It is `NULL` for config/plugin rows.
+
+No separate index is needed on `(database_name, name)` because the primary key already creates one. Do not add a `queries_database_published_idx` index for now.
+
+`QueryResource.resources_sql()` can become:
+
+```sql
+SELECT q.database_name AS parent, q.name AS child
+FROM queries q
+JOIN catalog_databases cd ON cd.database_name = q.database_name
+```
+
+The join keeps persisted queries for detached databases from appearing as live resources.
+
+## Config and plugin migration
+
+`datasette.yaml` can continue to support `databases: {db}: queries:` blocks, but core should import them directly into the internal `queries` tables at startup:
+
+1. Ensure the internal schema exists.
+2. Delete previous `source='config'` rows.
+3. Read configured query blocks for each live database.
+4. Normalize string definitions to `{"sql": ...}`.
+5. Insert rows into `queries`, storing explicit `params` as JSON in `parameters`.
+
+Plugins should move to:
+
+```python
+await datasette.add_query(...)
+await datasette.remove_query(...)
+```
+
+Remove the old `canned_queries()` hookspec and all core calls to it. If compatibility is needed, build `datasette-old-canned-queries` later as a plugin that restores the hook and imports old hook results using `datasette.add_query()`.
+
+## Permission model
+
+Add core actions:
+
+- `insert-query`, database-level, for creating queries in a database.
+- `publish-query`, database-level, for marking read-only queries as executable by actors who lack `execute-sql`.
+- `update-query`, query-level, for modifying existing query definitions.
+- `delete-query`, query-level, for deleting existing query definitions.
+
+User-created query creation requires:
+
+- `execute-sql` on `DatabaseResource(database)`
+- `insert-query` on `DatabaseResource(database)`
+- If analysis shows the query is writable, the table-level write permissions described in the writable query section.
+
+Setting `published=1` requires:
+
+- `publish-query` on `DatabaseResource(database)`
+- The query must be read-only according to `Database.analyze_sql()`.
+
+Updating an existing query requires:
+
+- `update-query` on `QueryResource(database, query)` or default owner permission for a user-owned row.
+- If the SQL changes, also require `execute-sql` on the database.
+- If the changed SQL is writable, also require the table-level write permissions described in the writable query section.
+- If `published` changes from `0` to `1`, also require `publish-query` on the database.
+
+Deleting an existing query requires:
+
+- `delete-query` on `QueryResource(database, query)` or default owner permission for a user-owned row.
+
+Default owner permissions:
+
+- For `source='user' AND owner_id = actor.id`, grant `update-query` and `delete-query`.
+- Do not automatically grant execution if the user no longer has the execution permission described below.
+
+## Executing queries
+
+Default execution rule for read-only queries:
+
+- If `published=0`, the actor needs `execute-sql` on the database.
+- If `published=1`, the actor can execute the query without `execute-sql`.
+
+Default execution rule for user-created writable queries:
+
+- `published` must be `0`.
+- The actor must have `view-query`.
+- The actor must currently have every write permission required by fresh `Database.analyze_sql()` results for the query SQL.
+
+Implementation:
+
+- Remove `view-query` from the broad `DEFAULT_ALLOW_ACTIONS` set.
+- Replace it with query-aware default `view-query` permission SQL.
+- For `published=1 AND is_write=0`, emit a child-level `view-query` allow.
+- For `published=0 AND is_write=0`, emit child-level `view-query` allows for queries whose parent database is in the actor's `execute-sql` allowed resources.
+- For `is_write=1 AND source='user'`, emit `view-query` only for the owner or actors with explicit `view-query` permission, then have `QueryView` perform the fresh analysis/table-permission check before execution.
+- For trusted writable queries, preserve current behavior by emitting child-level `view-query` allows for `is_write=1 AND source IN ('config', 'plugin')` when Datasette is not running with `--default-deny`.
+
+For read-only queries this keeps `QueryView` simple: it checks `view-query` for the query resource, and the default permission hook encodes the relationship with `execute-sql`. User-created writable queries need one additional runtime permission check because their required table permissions are derived from fresh SQL analysis.
+
+Explicit deny rules should still be able to block a published query.
+
+## Writable queries
+
+Writable user-created queries should be in scope, guarded by `Database.analyze_sql()`.
+
+The secure rule: a user can create, update, or execute a writable user-created query only if they currently have the corresponding write permissions for every table the SQL can affect.
+
+`Database.analyze_sql(sql, params=None)` runs the SQL through SQLite's authorizer on an isolated connection and returns a `SQLAnalysis` object containing `SQLTableAccess` rows:
+
+- `operation`: `read`, `insert`, `update`, or `delete`
+- `database`: Datasette database name for `main`, or SQLite schema name where no Datasette mapping exists
+- `table`: affected table or view
+- `columns`: read/updated columns where SQLite reports them
+- `source`: trigger/view/CTE source when SQLite reports one
+
+Validation flow for user-created queries:
+
+1. Derive named parameters from the SQL and pass harmless placeholder values into `db.analyze_sql()` so SQLite can prepare statements with bindings.
+2. If analysis raises a SQLite error, reject the query.
+3. If every table access is `read`, treat the query as read-only and require `execute-sql` plus `insert-query`/`update-query` as described above.
+4. If any table access is `insert`, `update`, or `delete`, treat the query as writable and force `published=0`.
+5. Reject writable user-created queries that access a database other than the database they are being saved against, until `analyze_sql()` can reliably map attached SQLite schemas back to Datasette database names.
+6. For every write access returned by analysis, require the corresponding permission on `TableResource(access.database, access.table)`:
+   - `insert` -> `insert-row`
+   - `update` -> `update-row`
+   - `delete` -> `delete-row`
+7. Include write accesses reported from triggers and views, since those are real side effects.
+8. Re-run the same analysis and permission checks when SQL changes through `update_query()` or `POST .../-/update`.
+9. Re-run analysis before executing user-created writable queries, so schema or trigger changes cannot leave a previously saved query with stale permission assumptions.
+
+The user-facing API should not trust a submitted `is_write` value. It should derive `is_write` from analysis.
+
+Trusted configuration and plugin code can still call `datasette.add_query(..., is_write=True, ...)`. Those are treated as deployment/admin-authored queries. They keep the existing execution model: they require `view-query`, and the default `view-query` hook should preserve current default-open behavior for trusted writable queries while still respecting `--default-deny`.
+
+Fail closed cases for user-created writable queries:
+
+- Analysis fails.
+- Analysis reports any write operation that cannot be mapped to a Datasette table resource.
+- Analysis reports writes outside the target database.
+- The actor lacks any required table write permission.
+- `published=1` is requested.
+
+This gives us writable user-created queries without letting `execute-sql` alone become a path to create arbitrary write endpoints.
+
+## HTTP API sketch
+
+JSON endpoints should follow Datasette's existing write API style: use `POST` plus action paths such as `/-/insert`, `/-/update`, and `/-/delete`, not HTTP `PATCH` or `DELETE`.
+
+Endpoints:
+
+- `GET /{database}/-/queries` lists query definitions the actor can view or manage, probably paginated.
+- `POST /{database}/-/queries/-/insert` creates a query.
+- `GET /{database}/{query}/-/definition` returns one query definition without executing it.
+- `POST /{database}/{query}/-/update` updates one query.
+- `POST /{database}/{query}/-/delete` deletes one query.
+
+Create request:
+
+```json
+{
+  "query": {
+    "name": "top_customers",
+    "sql": "select * from customers order by revenue desc limit 20",
+    "title": "Top customers",
+    "description": "Highest revenue customers",
+    "published": false,
+    "parameters": ["region"]
+  }
+}
+```
+
+Successful create returns `201` and the created query definition:
+
+```json
+{
+  "ok": true,
+  "query": {
+    "database": "fixtures",
+    "name": "top_customers",
+    "sql": "select * from customers order by revenue desc limit 20",
+    "title": "Top customers",
+    "description": "Highest revenue customers",
+    "published": false,
+    "parameters": ["region"]
+  }
+}
+```
+
+Update request, imitating `RowUpdateView`:
+
+```json
+{
+  "update": {
+    "title": "Top customers by revenue",
+    "published": true
+  },
+  "return": true
+}
+```
+
+Successful update returns `{"ok": true}` by default. With `"return": true`, return the updated query definition:
+
+```json
+{
+  "ok": true,
+  "query": {
+    "database": "fixtures",
+    "name": "top_customers",
+    "sql": "select * from customers order by revenue desc limit 20",
+    "title": "Top customers by revenue",
+    "published": true
+  }
+}
+```
+
+Delete request:
+
+```http
+POST /{database}/{query}/-/delete
+Content-Type: application/json
+```
+
+Successful delete returns:
+
+```json
+{
+  "ok": true
+}
+```
+
+Validation:
+
+- Update bodies must be dictionaries containing an `update` dictionary, with optional `return`; invalid keys return `{"ok": false, "errors": [...]}`.
+- Validate route-safe query names.
+- Reject names that collide with a table or view in the same database, since table routes currently win over query routes.
+- Analyze user-created SQL with `Database.analyze_sql()`.
+- Use `validate_sql_select(sql)` as the read-only fast path when analysis shows only reads, but do not require it for writable queries that pass analysis and permission checks.
+- Reject magic parameters such as `:_actor_id`, `:_cookie_*`, and `:_header_*` for user-created queries.
+- Reject client-supplied `is_write`; derive it from analysis.
+- Reject writable-only success/error fields for read-only queries.
+
+## Python API sketch
+
+Add methods on `Datasette`:
+
+```python
+await datasette.add_query(
+    database,
+    name,
+    sql,
+    title=None,
+    description=None,
+    description_html=None,
+    hide_sql=False,
+    fragment=None,
+    parameters=None,
+    is_write=False,
+    published=False,
+    source="plugin",
+    owner_id=None,
+    on_success_message=None,
+    on_success_message_sql=None,
+    on_success_redirect=None,
+    on_error_message=None,
+    on_error_redirect=None,
+    replace=True,
+)
+
+await datasette.update_query(
+    database,
+    name,
+    *,
+    sql=UNCHANGED,
+    title=UNCHANGED,
+    description=UNCHANGED,
+    description_html=UNCHANGED,
+    hide_sql=UNCHANGED,
+    fragment=UNCHANGED,
+    parameters=UNCHANGED,
+    is_write=UNCHANGED,
+    published=UNCHANGED,
+    source=UNCHANGED,
+    owner_id=UNCHANGED,
+    on_success_message=UNCHANGED,
+    on_success_message_sql=UNCHANGED,
+    on_success_redirect=UNCHANGED,
+    on_error_message=UNCHANGED,
+    on_error_redirect=UNCHANGED,
+)
+
+await datasette.remove_query(database, name, source=None)
+
+await datasette.get_query(database, name)
+await datasette.get_queries(database)
+```
+
+`update_query()` should use an internal sentinel default such as `UNCHANGED = object()` so callers can distinguish "leave this column alone" from "set this column to `NULL`":
+
+```python
+await datasette.update_query(
+    "fixtures",
+    "top_customers",
+    on_success_redirect=None,
+)
+```
+
+That call should set `on_success_redirect` to SQL `NULL`; omitting `on_success_redirect` should leave the existing value unchanged.
+
+Implementation detail: build the `UPDATE` statement dynamically from fields whose value is not `UNCHANGED`, validate non-nullable fields before writing, and update `updated_at` whenever at least one field changes.
+
+The read methods should reconstruct the existing dictionary shape used by query execution and templates, with `name`, `sql`, display fields, write fields, `params`, `published`, `owner_id`, and `source`. `parameters` should be returned as the decoded JSON array and exposed as `params` where existing query execution code expects that key.
+
+## Query page save UI
+
+On `/{database}/-/query`, if the actor has both `execute-sql` and `insert-query`, show a save control for valid read-only SQL. That page already executes read-only arbitrary SQL, so the first UI can stay read-only even though the JSON API can accept writable SQL after `Database.analyze_sql()` validation.
+
+The save form should call `POST /{database}/-/queries/-/insert` and default to `published=false`.
+
+If the actor also has `publish-query`, include a publish control. The UI copy should make it clear that publishing allows people without arbitrary SQL permission to run this query.
+
+## Dedicated create query UI
+
+Add `/{database}/-/queries/-/create` for the fuller query authoring flow, including writable queries.
+
+This page should require `execute-sql` and `insert-query` to access. It should provide a SQL editor and a mode control:
+
+- Read-only
+- Writable
+
+Read-only mode can share the same fields as the arbitrary SQL save flow: name, title, description, parameters, and optional published status if the actor has `publish-query`.
+
+Writable mode should always run `Database.analyze_sql()` and show an analysis panel before saving:
+
+- detected operation
+- database and table
+- required permission
+- whether the actor has that permission
+- source, when the operation comes from a trigger or view
+
+The Save button should be disabled until analysis succeeds and every required table write permission is allowed. Writable mode should not show a publish control, because user-created writable queries cannot be published.
+
+The existing edit-SQL flow from query pages can continue to point back to arbitrary SQL. A later enhancement can add "update this query" when the actor owns it or has `update-query`.
+
+## Test plan
+
+- Internal schema creates `queries`.
+- Query parameters are stored in the `queries.parameters` text column as a JSON array of names.
+- Config `queries:` blocks import into internal tables.
+- Legacy string query definitions normalize to SQL rows.
+- The old `canned_queries()` hook is no longer called by core.
+- `QueryResource.resources_sql()` returns rows from `queries`.
+- Database page and `/-/jump` list queries from the internal DB.
+- `view-query` is no longer globally default-allowed; default query permissions come from the query-aware hook.
+- Unpublished read-only query requires `execute-sql` to execute.
+- Published read-only query can be executed without `execute-sql`.
+- Setting `published=true` requires `publish-query`.
+- User-created query requires both `execute-sql` and `insert-query`.
+- User-created writable query creation uses `Database.analyze_sql()` and requires matching `insert-row`, `update-row`, and/or `delete-row` permissions for every reported write access.
+- `/{database}/-/queries/-/create` provides the writable-query authoring UI with an analysis panel and disabled save until all required write permissions pass.
+- User-created writable query execution re-runs `Database.analyze_sql()` and re-checks table write permissions.
+- User-created writable query cannot be published.
+- Query update uses `POST /{database}/{query}/-/update` with an `{"update": {...}}` body.
+- Query delete uses `POST /{database}/{query}/-/delete`.
+- There are no `PATCH` or HTTP `DELETE` routes for query management.
+- `datasette.update_query(..., field=None)` writes `NULL`, while omitted fields are left unchanged.
+- Owner gets default `update-query` and `delete-query` for their own user-created rows.
+- Admin can manage other users' queries with `update-query` and `delete-query`.
+- User API rejects magic parameters.
+- User API rejects writable queries if analysis fails, reports writes outside the target database, or reports writes the actor is not allowed to perform.
+- Trusted config/plugin writable queries still execute through `view-query`.
+- Trusted config/plugin writable queries are not default-allowed under `--default-deny`.
+- Persisted internal DB does not expose queries for detached databases.

-``datasette`` - :ref:`internals_datasette`
-    You can use this to access plugin configuration options via ``datasette.plugin_config(your_plugin_name)``, or to execute SQL queries.
-
-``database`` - string
-    The name of the database.
-
-``actor`` - dictionary or None
-    The currently authenticated :ref:`actor <authentication_actor>`.
-
-Use this hook to return a dictionary of additional :ref:`canned query <canned_queries>` definitions for the specified database. The return value should be the same shape as the JSON described in the :ref:`canned query <canned_queries>` documentation.

-                }
-            }
-
-The hook can alternatively return an awaitable function that returns a list. Here's an example that returns queries that have been stored in the ``saved_queries`` database table, if one exists:
-
-.. code-block:: python
-
-    from datasette import hookimpl

-                results = await db.execute(
-                    "select name, sql from saved_queries"
-                )

-                    result["name"]: {"sql": result["sql"]}
-                    for result in results
-                }
-
-        return inner
-
-The actor parameter can be used to include the currently authenticated actor in your decision. Here's an example that returns saved queries that were saved by that actor:
-
-.. code-block:: python
-
-    from datasette import hookimpl
-
-
-    @hookimpl
-    def canned_queries(datasette, database, actor):
-        async def inner():
-            db = datasette.get_database(database)
-            if actor is not None and await db.table_exists(
-                "saved_queries"

-                results = await db.execute(
-                    "select name, sql from saved_queries where actor_id = :id",
-                    {"id": actor["id"]},
-                )
-                return {
-                    result["name"]: {"sql": result["sql"]}

Subject: [PATCH 061/137] Support multi-line parameters on /db/-/execute-write

Refs https://github.com/simonw/datasette/issues/2742#issuecomment-4536317049

Each paramater input now has an expand/collapse button toggle to turn into a textarea.

If you paste text that includes at least one newline it toggles automatically.

Subject: [PATCH 070/137] Removed some no-longer-necessary code, simplified

view-query is back in the default allow actions now. We have
other mechanisms that work for controlling visibility, and
the fact that queries default to running with the permissions
of the actor makes this safe.

-# Queries in the internal database
-
-Plan for <https://github.com/simonw/datasette/issues/2735>.
-
-## Goal
-
-Move named query definitions into Datasette's internal database, so hundreds or thousands of queries can be listed, searched, permission-filtered, managed, and executed efficiently.
-
-Terminology change: these are now "queries", not "canned queries". Legacy code and documentation can mention the old name only when describing compatibility or migration.
-
-## Decisions so far
-
-- Internal table name: `queries`.
-- Query definitions should use real columns, not a JSON blob for all options.
-- Query parameter names live in a `parameters` text column as a JSON array. No default values for parameters in this pass.
-- No separate index is needed for the privacy/trust flags yet.
-- User-created queries require `execute-sql` and `insert-query` on the database. They default to private, and writable queries additionally require matching table write permissions discovered by `Database.analyze_sql()`.
-- Configured queries default to trusted, which means actors who can view them can execute them without also holding `execute-sql` or the relevant write permissions. Config can opt out with `is_trusted: false`.
-- Add `update-query` and `delete-query`, so administrators can manage queries created by other users.
-- Remove the old `canned_queries()` hook from core. If we want compatibility later, build a separate `datasette-old-canned-queries` plugin.
-- Writable user-created queries can be supported using `Database.analyze_sql()`, provided we fail closed when analysis cannot prove the required permissions.
-
-## Current shape
-
-- Query definitions currently come from `datasette.yaml` or the `canned_queries()` plugin hook.
-- `Datasette.get_canned_queries(database_name, actor)` calls that hook every time it needs query definitions.
-- `QueryResource.resources_sql()` currently enumerates databases and calls the hook for each one, because permissions and `/-/jump` need query resources.
-- Query pages are visible if the actor has `view-query` for `QueryResource(database, query)`. Executing an untrusted stored query also checks `execute-sql` or the relevant write permissions.
-- Arbitrary SQL executes if the actor has `execute-sql` for `DatabaseResource(database)`.
-
-The main performance and architecture win is making query resource enumeration a direct SQL query against the internal database.
-
-## Proposed internal schema
-
-Start with one `queries` table.
-
-```sql
-CREATE TABLE IF NOT EXISTS queries (
-    database_name TEXT NOT NULL,
-    name TEXT NOT NULL,
-    sql TEXT NOT NULL,
-    title TEXT,
-    description TEXT,
-    description_html TEXT,
-    options TEXT NOT NULL DEFAULT '{}',
-    parameters TEXT NOT NULL DEFAULT '[]',
-    is_write INTEGER NOT NULL DEFAULT 0 CHECK (is_write IN (0, 1)),
-    is_private INTEGER NOT NULL DEFAULT 0 CHECK (is_private IN (0, 1)),
-    is_trusted INTEGER NOT NULL DEFAULT 0 CHECK (is_trusted IN (0, 1)),
-    source TEXT NOT NULL DEFAULT 'user',
-    owner_id TEXT,
-    created_at TEXT NOT NULL DEFAULT CURRENT_TIMESTAMP,
-    updated_at TEXT NOT NULL DEFAULT CURRENT_TIMESTAMP,
-    PRIMARY KEY (database_name, name)
-);
-
-CREATE INDEX IF NOT EXISTS queries_owner_idx
-    ON queries(owner_id);
-```
-
-Column notes:
-
-- `database_name`, `name`, and `sql` are the routing and execution core.
-- Display fields become columns: `title`, `description`, and `description_html`.
-- Less common presentation and writable-query behavior lives in `options`, stored as a JSON object. That covers `hide_sql`, `fragment`, `on_success_message`, `on_success_message_sql`, `on_success_redirect`, `on_error_message`, and `on_error_redirect`.
-- `parameters` is a JSON array of parameter names, stored as text. This preserves explicit parameter order, but does not support labels or default values.
-- Existing writable query behavior gets `is_write` as a column. Success/error messages, success/error redirects, and `on_success_message_sql` are stored in `options`.
-- `is_private` means the query is only visible to its owning actor. This is enforced as a permission restriction, so broader `view-query` grants do not expose private rows.
-- `is_trusted` means execution skips the usual `execute-sql` or write-permission checks after `view-query` has allowed access.
-- `source` distinguishes `user`, `config`, and `plugin` rows.
-- `owner_id` is the actor id for user-created rows. It is `NULL` for config/plugin rows.
-
-No separate index is needed on `(database_name, name)` because the primary key already creates one.
-
-`QueryResource.resources_sql()` can become:
-
-```sql
-SELECT q.database_name AS parent, q.name AS child
-FROM queries q
-JOIN catalog_databases cd ON cd.database_name = q.database_name
-```
-
-The join keeps persisted queries for detached databases from appearing as live resources.
-
-## Config and plugin migration
-
-`datasette.yaml` can continue to support `databases: {db}: queries:` blocks, but core should import them directly into the internal `queries` tables at startup:
-
-1. Ensure the internal schema exists.
-2. Delete previous `source='config'` rows.
-3. Read configured query blocks for each live database.
-4. Normalize string definitions to `{"sql": ...}`.
-5. Insert rows into `queries`, storing explicit `params` as JSON in `parameters`.
-
-Plugins should move to:
-
-```python
-await datasette.add_query(...)
-await datasette.remove_query(...)
-```
-
-Remove the old `canned_queries()` hookspec and all core calls to it. If compatibility is needed, build `datasette-old-canned-queries` later as a plugin that restores the hook and imports old hook results using `datasette.add_query()`.
-
-## Permission model
-
-Add core actions:
-
-- `insert-query`, database-level, for creating queries in a database.
-- `update-query`, query-level, for modifying existing query definitions.
-- `delete-query`, query-level, for deleting existing query definitions.
-
-User-created query creation requires:
-
-- `execute-sql` on `DatabaseResource(database)`
-- `insert-query` on `DatabaseResource(database)`
-- If analysis shows the query is writable, the table-level write permissions described in the writable query section.
-
-Updating an existing query requires:
-
-- `update-query` on `QueryResource(database, query)` or default owner permission for a user-owned row.
-- If the SQL changes, also require `execute-sql` on the database.
-- If the changed SQL is writable, also require the table-level write permissions described in the writable query section.
-
-Deleting an existing query requires:
-
-- `delete-query` on `QueryResource(database, query)` or default owner permission for a user-owned row.
-
-Default owner permissions:
-
-- For `source='user' AND owner_id = actor.id`, grant `update-query` and `delete-query`.
-- For `source='user' AND owner_id = actor.id`, grant `view-query`. If the query is private, restriction SQL ensures no other actor sees it through a broader grant.
-
-## Executing queries
-
-Default execution rule for read-only queries:
-
-- If `is_trusted=0`, the actor needs `execute-sql` on the database.
-- If `is_trusted=1`, the actor can execute the query without `execute-sql`, provided `view-query` allows access.
-
-Default execution rule for user-created writable queries:
-
-- `is_trusted` must be `0`.
-- The actor must have `view-query`.
-- The actor must currently have every write permission required by fresh `Database.analyze_sql()` results for the query SQL.
-
-Implementation:
-
-- Keep `view-query` in the broad `DEFAULT_ALLOW_ACTIONS` set, so saved queries remain visible by default in all-public Datasette.
-- Emit default `view-query` allows for the owning actor.
-- Use `restriction_sql` to limit private rows to their owner even when broader `view-query` permissions exist.
-- Have `QueryView` perform the fresh `execute-sql` or table-permission check before execution unless the row has `is_trusted=1`.
-
-For read-only queries this keeps `QueryView` explicit: it checks `view-query` for the query resource, then checks `execute-sql` unless the row is trusted. User-created writable queries need one additional runtime permission check because their required table permissions are derived from fresh SQL analysis.
-
-Explicit deny rules should still be able to block a query, and `--default-deny` still blocks trusted queries unless something grants `view-query`.
-
-## Writable queries
-
-Writable user-created queries should be in scope, guarded by `Database.analyze_sql()`.
-
-The secure rule: a user can create, update, or execute a writable user-created query only if they currently have the corresponding write permissions for every table the SQL can affect.
-
-`Database.analyze_sql(sql, params=None)` runs the SQL through SQLite's authorizer on an isolated connection and returns a `SQLAnalysis` object containing `SQLTableAccess` rows:
-
-- `operation`: `read`, `insert`, `update`, or `delete`
-- `database`: Datasette database name for `main`, or SQLite schema name where no Datasette mapping exists
-- `table`: affected table or view
-- `columns`: read/updated columns where SQLite reports them
-- `source`: trigger/view/CTE source when SQLite reports one
-
-Validation flow for user-created queries:
-
-1. Derive named parameters from the SQL and pass harmless placeholder values into `db.analyze_sql()` so SQLite can prepare statements with bindings.
-2. If analysis raises a SQLite error, reject the query.
-3. If every table access is `read`, treat the query as read-only and require `execute-sql` plus `insert-query`/`update-query` as described above.
-4. If any table access is `insert`, `update`, or `delete`, treat the query as writable and force `is_trusted=0`.
-5. Reject writable user-created queries that access a database other than the database they are being saved against, until `analyze_sql()` can reliably map attached SQLite schemas back to Datasette database names.
-6. For every write access returned by analysis, require the corresponding permission on `TableResource(access.database, access.table)`:
-   - `insert` -> `insert-row`
-   - `update` -> `update-row`
-   - `delete` -> `delete-row`
-7. Include write accesses reported from triggers and views, since those are real side effects.
-8. Re-run the same analysis and permission checks when SQL changes through `update_query()` or `POST .../-/update`.
-9. Re-run analysis before executing user-created writable queries, so schema or trigger changes cannot leave a previously saved query with stale permission assumptions.
-
-The user-facing API should not trust a submitted `is_write` value. It should derive `is_write` from analysis.
-
-Trusted configuration and plugin code can still call `datasette.add_query(..., is_write=True, ...)`. Those are treated as deployment/admin-authored queries. They keep the existing execution model: they require `view-query`, and the default `view-query` hook should preserve current default-open behavior for trusted writable queries while still respecting `--default-deny`.
-
-Fail closed cases for user-created writable queries:
-
-- Analysis fails.
-- Analysis reports any write operation that cannot be mapped to a Datasette table resource.
-- Analysis reports writes outside the target database.
-- The actor lacks any required table write permission.
-- `is_trusted=1` is requested through the user-facing API.
-
-This gives us writable user-created queries without letting `execute-sql` alone become a path to create arbitrary write endpoints.
-
-## HTTP API sketch
-
-JSON endpoints should follow Datasette's existing write API style: use `POST` plus action paths such as `/-/insert`, `/-/update`, and `/-/delete`, not HTTP `PATCH` or `DELETE`.
-
-Endpoints:
-
-- `GET /-/queries` and `GET /{database}/-/queries` show searchable HTML query browsers. `GET /-/queries.json` lists query definitions across every database the actor can view; `GET /{database}/-/queries.json` scopes that list to one database. Both JSON endpoints use cursor pagination with `_next` and `_size`.
-- `POST /{database}/-/queries/insert` creates a query.
-- `GET /{database}/{query}/-/definition` returns one query definition without executing it.
-- `POST /{database}/{query}/-/update` updates one query.
-- `POST /{database}/{query}/-/delete` deletes one query.
-
-Create request:
-
-```json
-{
-  "query": {
-    "name": "top_customers",
-    "sql": "select * from customers order by revenue desc limit 20",
-    "title": "Top customers",
-    "description": "Highest revenue customers",
-    "is_private": true,
-    "parameters": ["region"]
-  }
-}
-```
-
-Successful create returns `201` and the created query definition:
-
-```json
-{
-  "ok": true,
-  "query": {
-    "database": "fixtures",
-    "name": "top_customers",
-    "sql": "select * from customers order by revenue desc limit 20",
-    "title": "Top customers",
-    "description": "Highest revenue customers",
-    "is_private": true,
-    "is_trusted": false,
-    "parameters": ["region"]
-  }
-}
-```
-
-Update request, imitating `RowUpdateView`:
-
-```json
-{
-  "update": {
-    "title": "Top customers by revenue",
-    "is_private": false
-  },
-  "return": true
-}
-```
-
-Successful update returns `{"ok": true}` by default. With `"return": true`, return the updated query definition:
-
-```json
-{
-  "ok": true,
-  "query": {
-    "database": "fixtures",
-    "name": "top_customers",
-    "sql": "select * from customers order by revenue desc limit 20",
-    "title": "Top customers by revenue",
-    "is_private": false,
-    "is_trusted": false
-  }
-}
-```
-
-Delete request:
-
-```http
-POST /{database}/{query}/-/delete
-Content-Type: application/json
-```
-
-Successful delete returns:
-
-```json
-{
-  "ok": true
-}
-```
-
-Validation:
-
-- Update bodies must be dictionaries containing an `update` dictionary, with optional `return`; invalid keys return `{"ok": false, "errors": [...]}`.
-- Validate route-safe query names.
-- Reject names that collide with a table or view in the same database, since table routes currently win over query routes.
-- Analyze user-created SQL with `Database.analyze_sql()`.
-- Use `validate_sql_select(sql)` as the read-only fast path when analysis shows only reads, but do not require it for writable queries that pass analysis and permission checks.
-- Reject magic parameters such as `:_actor_id`, `:_cookie_*`, and `:_header_*` for user-created queries.
-- Reject client-supplied `is_write`; derive it from analysis.
-- Reject writable-only success/error fields for read-only queries.
-
-## Python API sketch
-
-Add methods on `Datasette`:
-
-```python
-await datasette.add_query(
-    database,
-    name,
-    sql,
-    title=None,
-    description=None,
-    description_html=None,
-    hide_sql=False,
-    fragment=None,
-    parameters=None,
-    is_write=False,
-    is_private=False,
-    is_trusted=False,
-    source="plugin",
-    owner_id=None,
-    on_success_message=None,
-    on_success_message_sql=None,
-    on_success_redirect=None,
-    on_error_message=None,
-    on_error_redirect=None,
-    replace=True,
-)
-
-await datasette.update_query(
-    database,
-    name,
-    *,
-    sql=UNCHANGED,
-    title=UNCHANGED,
-    description=UNCHANGED,
-    description_html=UNCHANGED,
-    hide_sql=UNCHANGED,
-    fragment=UNCHANGED,
-    parameters=UNCHANGED,
-    is_write=UNCHANGED,
-    is_private=UNCHANGED,
-    is_trusted=UNCHANGED,
-    source=UNCHANGED,
-    owner_id=UNCHANGED,
-    on_success_message=UNCHANGED,
-    on_success_message_sql=UNCHANGED,
-    on_success_redirect=UNCHANGED,
-    on_error_message=UNCHANGED,
-    on_error_redirect=UNCHANGED,
-)
-
-await datasette.remove_query(database, name, source=None)
-
-await datasette.get_query(database, name)
-await datasette.list_queries(
-    database,
-    actor=None,
-    limit=50,
-    cursor=None,
-    q=None,
-    is_write=None,
-    is_private=None,
-    is_trusted=None,
-    source=None,
-    owner_id=None,
-)
-```
-
-`list_queries()` should return a bounded page shaped like `{"queries": [...], "next": "...", "has_more": true, "limit": 50}`. The `next` value is an opaque cursor token, not an offset. Passing `database=None` lists visible queries across all live databases, still filtered through `view-query` permission SQL.
-
-`update_query()` should use an internal sentinel default such as `UNCHANGED = object()` so callers can distinguish "leave this column alone" from "set this column to `NULL`":
-
-```python
-await datasette.update_query(
-    "fixtures",
-    "top_customers",
-    on_success_redirect=None,
-)
-```
-
-For column-backed fields, `None` should write SQL `NULL`. For option fields, `None` should remove that key from the JSON object so `get_query()` returns `None`; omitting the field should leave the existing option unchanged.
-
-Implementation detail: build the `UPDATE` statement dynamically from fields whose value is not `UNCHANGED`, validate non-nullable fields before writing, and update `updated_at` whenever at least one field changes.
-
-The read methods should reconstruct the existing dictionary shape used by query execution and templates, with `name`, `sql`, display fields, write fields, `params`, `is_private`, `is_trusted`, `owner_id`, and `source`. `parameters` should be returned as the decoded JSON array and exposed as `params` where existing query execution code expects that key. Option values should be unpacked from the `options` JSON object and returned as the same top-level keys accepted by `add_query()` and `update_query()`.
-
-## Query page save UI
-
-On `/{database}/-/query`, if the actor has both `execute-sql` and `insert-query`, show a save control for valid read-only SQL. That page already executes read-only arbitrary SQL, so the first UI can stay read-only even though the JSON API can accept writable SQL after `Database.analyze_sql()` validation.
-
-The save form should call `POST /{database}/-/queries/insert` and default to `is_private=true`.
-
-On `/{database}`, show a preview of the first 5 visible queries using `list_queries(..., limit=5)`. If the page has `has_more`, show a link to `/{database}/-/queries` rather than rendering hundreds or thousands of query links inline. The full `/{database}/-/queries` page provides search, filters, and cursor pagination. The global `/-/queries` page reuses the same interface and shows the database for each query.
-
-## Dedicated create query UI
-
-Add `/{database}/-/queries/-/create` for the fuller query authoring flow, including writable queries.
-
-This page should require `execute-sql` and `insert-query` to access. It should provide a SQL editor and a mode control:
-
-- Read-only
-- Writable
-
-Read-only mode can share the same fields as the arbitrary SQL save flow: name, title, description, parameters, and privacy status.
-
-Writable mode should always run `Database.analyze_sql()` and show an analysis panel before saving:
-
-- detected operation
-- database and table
-- required permission
-- whether the actor has that permission
-- source, when the operation comes from a trigger or view
-
-The Save button should be disabled until analysis succeeds and every required table write permission is allowed.
-
-The existing edit-SQL flow from query pages can continue to point back to arbitrary SQL. A later enhancement can add "update this query" when the actor owns it or has `update-query`.
-
-## Test plan
-
-- Internal schema creates `queries`.
-- Query parameters are stored in the `queries.parameters` text column as a JSON array of names.
-- Config `queries:` blocks import into internal tables.
-- Legacy string query definitions normalize to SQL rows.
-- The old `canned_queries()` hook is no longer called by core.
-- `QueryResource.resources_sql()` returns rows from `queries`.
-- Database page and `/-/jump` list queries from the internal DB.
-- `view-query` remains globally default-allowed, with `restriction_sql` narrowing private queries to their owner.
-- Private query is only visible to its owner, even when a broader `view-query` rule applies.
-- Non-trusted read-only query requires `execute-sql` to execute.
-- Trusted read-only query can be executed without `execute-sql` after `view-query` passes.
-- Config queries default to trusted and can opt out with `is_trusted: false`.
-- User API rejects client-supplied `is_trusted`.
-- User-created query requires both `execute-sql` and `insert-query`.
-- User-created writable query creation uses `Database.analyze_sql()` and requires matching `insert-row`, `update-row`, and/or `delete-row` permissions for every reported write access.
-- `/{database}/-/queries/-/create` provides the writable-query authoring UI with an analysis panel and disabled save until all required write permissions pass.
-- User-created writable query execution re-runs `Database.analyze_sql()` and re-checks table write permissions.
-- User-created writable query cannot be trusted through the user API.
-- Query update uses `POST /{database}/{query}/-/update` with an `{"update": {...}}` body.
-- Query delete uses `POST /{database}/{query}/-/delete`.
-- There are no `PATCH` or HTTP `DELETE` routes for query management.
-- `datasette.update_query(..., field=None)` writes `NULL` for column-backed fields and removes JSON keys for option fields, while omitted fields are left unchanged.
-- Owner gets default `update-query` and `delete-query` for their own user-created rows.
-- Admin can manage other users' queries with `update-query` and `delete-query`.
-- User API rejects magic parameters.
-- User API rejects writable queries if analysis fails, reports writes outside the target database, or reports writes the actor is not allowed to perform.
-- Trusted config/plugin writable queries still execute through `view-query`.
-- Trusted config/plugin writable queries are not default-allowed under `--default-deny`.
-- Persisted internal DB does not expose queries for detached databases.

+Stored queries
+~~~~~~~~~~~~~~
+
+Datasette stores both configured queries and user-created queries in the ``queries`` table in the :ref:`internal database <internals_internal>`. Configured queries come from the ``queries`` section of ``datasette.yaml``. User-created stored queries can be created from the SQL query page by actors with the :ref:`actions_store_query` and :ref:`actions_execute_sql` permissions. Writable stored queries also require the permissions needed for the writes they perform.
+
+Stored queries created by users default to private. Private stored queries can only be viewed, updated or deleted by the actor that created them. Broad ``view-query``, ``update-query`` or ``delete-query`` permission grants still do not allow other actors to access another actor's private stored queries.
+
+Stored queries created by users are untrusted. This means they execute using the permissions of the actor who runs them, as if that actor had pasted the SQL into the regular custom SQL interface or write SQL interface. Read-only stored queries require ``execute-sql``. Writable stored queries require ``execute-write-sql`` plus the relevant table-level write permissions.

+Trusted stored queries
+++++++++++++++++++++++
+
+A trusted stored query can execute with ``view-query`` permission alone. It skips the additional ``execute-sql`` and write permission checks that are applied to untrusted stored queries.
+
+Trusted stored queries should only be used for SQL that has been reviewed by someone trusted to configure the Datasette instance. For that reason, trusted stored queries can only be added using configuration. Users cannot create trusted stored queries through the web interface or the stored query JSON API.
+
+Queries defined in ``datasette.yaml`` are trusted by default:
+
+.. code-block:: yaml
+
+    databases:
+      mydatabase:
+        queries:
+          report:
+            sql: select * from report
+
+You can opt out of this behavior for a configured query using ``is_trusted: false``:

 Unreleased
 ----------
 
-- Fixed a bug where visiting ``/<database>/-/query`` without a ``?sql=`` parameter returned a 500 error. (:issue:`2743`)
+Stored queries
+~~~~~~~~~~~~~~
+
+- The previous "canned queries" feature has been renamed and expanded into :ref:`stored queries <stored_queries>`. Queries configured in ``datasette.yaml`` are now loaded into a new ``queries`` table in Datasette's :ref:`internal database <internals_internal_schema>`, alongside user-created stored queries. (:issue:`2735`)
+- New stored query management APIs: ``datasette.add_query()``, ``datasette.update_query()``, ``datasette.remove_query()``, ``datasette.get_query()``, ``datasette.list_queries()`` and ``datasette.count_queries()``. These replace the removed ``datasette.get_canned_query()`` and ``datasette.get_canned_queries()`` methods. (:issue:`2735`)
+- Users with :ref:`store-query <actions_store_query>` and :ref:`execute-sql <actions_execute_sql>` permission can create stored queries from the SQL query page or the new ``GET /<database>/-/queries/store`` form. (:issue:`2735`)
+- The database page now shows a count and preview of stored queries, capped at five, and links to new paginated query browsers at ``/-/queries`` and ``/<database>/-/queries``. Those browsers support search. (:issue:`2735`)
+- Stored queries created by users default to private and untrusted. Private stored queries can only be viewed, updated or deleted by their owner, even if another actor has broad ``view-query``, ``update-query`` or ``delete-query`` permission. Untrusted stored queries execute using the permissions of the actor running them. See :ref:`stored_queries` and :ref:`trusted_stored_queries` for details. (:issue:`2735`)
+- New ``store-query``, ``update-query`` and ``delete-query`` permissions, plus updated semantics for :ref:`view-query <actions_view_query>`. Trusted stored queries can still execute with ``view-query`` alone; untrusted read queries also require :ref:`execute-sql <actions_execute_sql>` and untrusted writable queries require :ref:`execute-write-sql <actions_execute_write_sql>` plus the relevant table-level write permissions. (:issue:`2735`)
+
+Write SQL UI
+~~~~~~~~~~~~
+
+- New "Write to this database" interface at ``/<database>/-/execute-write`` for running arbitrary writable SQL against mutable databases. The form extracts named parameters, analyzes the SQL, shows the table operations that will be attempted and links to a newly inserted row when a single-row insert succeeds. (:issue:`2742`)
+- Added the new :ref:`execute-write-sql <actions_execute_write_sql>` permission for running arbitrary writable SQL. Execution is also gated by table-level permissions such as :ref:`insert-row <actions_insert_row>`, :ref:`update-row <actions_update_row>` and :ref:`delete-row <actions_delete_row>`, and writes to attached databases are rejected. (:issue:`2742`)
+
+Plugin API changes
+~~~~~~~~~~~~~~~~~~
+
 - The ``top_canned_query()`` plugin hook has been renamed to :ref:`top_stored_query() <plugin_hook_top_stored_query>`. (:issue:`2747`)
-- The ``canned_queries()`` plugin hook has been removed. Plugins can use the new ``datasette.add_query()``, ``datasette.update_query()`` and ``datasette.remove_query()`` methods to manage stored queries instead.
-- The ``datasette.get_canned_query()`` and ``datasette.get_canned_queries()`` methods have been removed. Plugins can use ``datasette.get_query()`` and ``datasette.list_queries()`` instead.
+- The ``canned_queries()`` plugin hook has been removed. Plugins can use the new stored query methods together with :ref:`startup() <plugin_hook_startup>` to register queries. (:issue:`2735`)
+
+Bug fixes
+~~~~~~~~~
+
+- Fixed a bug where visiting ``/<database>/-/query`` without a ``?sql=`` parameter returned a 500 error. (:issue:`2743`)

+Stored queries
+--------------
+
+:ref:`Stored queries <stored_queries>` are stored in the ``queries`` table in the :ref:`internal database <internals_internal>`. Plugins can use the following methods to add, update, list and remove stored queries.
+
+.. _datasette_add_query:
+
+await .add_query(database, name, sql, ...)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Adds a stored query.
+
+.. code-block:: python
+
+    async def add_query(
+        self,
+        database,
+        name,
+        sql,
+        *,
+        title=None,
+        description=None,
+        description_html=None,
+        hide_sql=False,
+        fragment=None,
+        parameters=None,
+        is_write=False,
+        is_private=False,
+        is_trusted=False,
+        source="plugin",
+        owner_id=None,
+        on_success_message=None,
+        on_success_message_sql=None,
+        on_success_redirect=None,
+        on_error_message=None,
+        on_error_redirect=None,
+        replace=True,
+    ): ...
+
+``database`` - string
+    The name of the database this query should belong to.
+``name`` - string
+    The name of the stored query, used in the URL for that query.
+``sql`` - string
+    The SQL for the stored query.
+``title`` - string, optional
+    A display title for the query.
+``description`` - string, optional
+    A plain text description.
+``description_html`` - string, optional
+    An HTML description.
+``hide_sql`` - boolean, optional
+    Set to ``True`` to hide the SQL by default on the query page.
+``fragment`` - string, optional
+    A URL fragment to append to query links, for example ``"chart"``.
+``parameters`` - list of strings, optional
+    Explicit parameter names for the query form. If omitted, Datasette derives parameters from the SQL.
+``is_write`` - boolean, optional
+    Set to ``True`` for writable queries. They will the run against the SQLite write connection for the database.
+``is_private`` - boolean, optional
+    Set to ``True`` for private queries. Private queries can only be viewed, updated or deleted by their owner.
+``is_trusted`` - boolean, optional
+    Set to ``True`` for :ref:`trusted stored queries <trusted_stored_queries>`.
+``source`` - string, optional
+    Identifies where the query came from. Defaults to ``"plugin"``.
+``owner_id`` - string, optional
+    Actor ID of the query owner, used by private query permissions.
+``on_success_message``, ``on_success_message_sql``, ``on_success_redirect``, ``on_error_message``, ``on_error_redirect`` - strings, optional
+    Options for :ref:`writable queries <queries_writable>`.
+``replace`` - boolean, optional
+    Defaults to ``True``, which replaces any existing stored query with the same ``database`` and ``name``. Set this to ``False`` to raise a SQLite integrity error if the query already exists.
+
+Example:
+
+.. code-block:: python
+
+    await datasette.add_query(
+        database="fixtures",
+        name="recent_rows",
+        sql="select * from facetable order by created desc limit 10",
+        title="Recent rows",
+        source="my-plugin",
+    )
+
+.. _datasette_update_query:
+
+await .update_query(database, name, ...)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Updates fields for an existing stored query. Only keyword arguments that are provided will be changed.
+
+The available keyword arguments are the same as those for :ref:`datasette_add_query`, except for ``replace``. Pass ``None`` to clear optional text fields and options such as ``on_success_redirect``. Passing ``hide_sql=False`` removes the ``hide_sql`` option.
+
+Example:
+
+.. code-block:: python
+
+    await datasette.update_query(
+        database="fixtures",
+        name="recent_rows",
+        title="Latest rows",
+        is_private=True,
+        owner_id="alice",
+    )
+
+.. _datasette_get_query:
+
+await .get_query(database, name)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Returns a stored query dictionary, or ``None`` if the query does not exist.
+
+The dictionary contains ``database``, ``name``, ``sql``, ``title``, ``description``, ``description_html``, ``hide_sql``, ``fragment``, ``parameters``, ``params``, ``is_write``, ``is_private``, ``is_trusted``, ``source``, ``owner_id``, ``on_success_message``, ``on_success_message_sql``, ``on_success_redirect``, ``on_error_message`` and ``on_error_redirect``.
+
+``parameters`` and ``params`` contain the same list of explicit parameter names.
+
+.. _datasette_list_queries:
+
+await .list_queries(database=None, ...)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Lists stored queries visible to the specified actor.
+
+.. code-block:: python
+
+    async def list_queries(
+        self,
+        database=None,
+        *,
+        actor=None,
+        limit=50,
+        cursor=None,
+        q=None,
+        is_write=None,
+        is_private=None,
+        is_trusted=None,
+        source=None,
+        owner_id=None,
+        include_private=False,
+    ): ...
+
+``database`` - string, optional
+    Restrict results to a specific database. Omit this to list queries across all databases.
+``actor`` - dictionary, optional
+    The authenticated actor. Results are filtered using that actor's ``view-query`` permission.
+``limit`` - integer, optional
+    Number of queries to return. Values are clamped to the range 1-1000.
+``cursor`` - string, optional
+    Pagination cursor from the previous page's ``next`` value.
+``q`` - string, optional
+    Search string matched against query name, title, description and SQL.
+``is_write``, ``is_private``, ``is_trusted`` - boolean, optional
+    Filter by those stored query flags.
+``source`` - string, optional
+    Filter by query source.
+``owner_id`` - string, optional
+    Filter by owner actor ID.
+``include_private`` - boolean, optional
+    Set to ``True`` to include a ``private`` boolean in each returned query dictionary indicating if anonymous users would be unable to view that query.
+
+The return value is a dictionary with these keys:
+
+``queries`` - list of dictionaries
+    Stored query dictionaries, in the same format returned by :ref:`datasette_get_query`.
+``next`` - string or None
+    Pagination cursor for the next page, if one exists.
+``has_more`` - boolean
+    ``True`` if another page of results is available.
+``limit`` - integer
+    The limit used for this page.
+
+.. _datasette_count_queries:
+
+await .count_queries(database=None, ...)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Counts stored queries visible to the specified actor. This accepts the same filtering keyword arguments as :ref:`datasette_list_queries`, except for ``limit``, ``cursor`` and ``include_private``.
+
+.. _datasette_remove_query:
+
+await .remove_query(database, name, source=None)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Removes a stored query.
+
+``database`` - string
+    The database the query belongs to.
+``name`` - string
+    The query name.
+``source`` - string, optional
+    If provided, only a query with this source will be removed.

Subject: [PATCH 108/137] Deny unsupported write SQL operations by default

Require view-table permission for reads discovered inside write SQL analysis, including INSERT ... SELECT and CREATE TABLE ... AS SELECT.

Record additional SQLite authorizer callbacks as Operation values so unsupported functions, savepoints, virtual table DDL, and unknown callbacks are denied unless explicitly handled.

Subject: [PATCH 109/137] Require full row mutation permissions for raw SQL

Raw SQL insert and update statements can have broader effects than their SQLite authorizer callbacks reveal. INSERT OR REPLACE and UPDATE OR REPLACE can delete conflicting rows while only surfacing insert or update operations.

Expand table insert and update operations to require insert-row, update-row, and delete-row together. Keep delete operations mapped to delete-row, and update the analysis UI/API to report and evaluate multiple required permissions for a single operation.

Subject: [PATCH 110/137] Deny user-authored schema table reads in write SQL

Stop marking sqlite_master and sqlite_schema reads as internal as soon as the SQLite authorizer reports them. The later DDL-aware pass still treats schema catalog access as internal when it accompanies semantic CREATE, ALTER, or DROP operations.

This makes explicit catalog reads in write SQL fall through to the deny-by-default path as unsupported read schema operations, preventing queries from copying private table definitions into writable tables.

 Datasette provides a write API for JSON data. This is a POST-only API that requires an authenticated API token, see :ref:`CreateTokenView`. The token will need to have the specified :ref:`authentication_permissions`.
 
+.. _ExecuteWriteView:
+
+Executing write SQL
+~~~~~~~~~~~~~~~~~~~
+
+Actors with the :ref:`actions_execute_write_sql` permission can execute arbitrary writable SQL against a mutable database using ``/-/execute-write``.
+
+::
+
+    POST /<database>/-/execute-write
+    Content-Type: application/json
+    Authorization: Bearer dstok_<rest-of-token>
+
+The request body must include a ``"sql"`` string. Named SQL parameters can be provided using the optional ``"params"`` object:
+
+.. code-block:: json
+
+    {
+        "sql": "insert into dogs (name) values (:name)",
+        "params": {
+            "name": "Cleo"
+        }
+    }
+
+The SQL must be writable. Read-only ``select`` queries should use the regular :ref:`custom SQL query API <sql>` instead.
+
+Datasette analyzes the SQL before executing it. The actor must have ``execute-write-sql`` permission for the database, and must also have any permissions required by the operations in the SQL. For example, inserts and updates against a table require ``insert-row``, ``update-row`` and ``delete-row`` permissions for that table. Reads performed as part of the write, such as ``insert into dogs select ... from other_table``, require ``view-table`` permission on the source table.
+
+A successful response includes a message, the SQLite ``rowcount`` and a summary of the operations that were executed:
+
+The shape of the ``"analysis"`` block is not yet considered a stable API and may change in future Datasette releases.
+
+.. code-block:: json
+
+    {
+        "ok": true,
+        "message": "Query executed, 1 row affected",
+        "rowcount": 1,
+        "analysis": [
+            {
+                "operation": "insert",
+                "database": "data",
+                "table": "dogs",
+                "required_permission": "insert-row, update-row, delete-row",
+                "source": null
+            }
+        ]
+    }
+
+If SQLite reports ``-1`` for the row count, the message will be ``"Query executed"``.
+
+Errors use the standard Datasette error format:
+
+.. code-block:: json
+
+    {
+        "ok": false,
+        "errors": [
+            "Permission denied: need execute-write-sql"
+        ]
+    }
+

Subject: [PATCH 119/137] Document write SQL analyzer restrictions

Expand the unreleased changelog with the deny-by-default operation analysis model, SQL function handling, and the VACUUM and virtual/shadow table restrictions for user-supplied write SQL.

Clarify the /-/execute-write JSON API documentation with the same restrictions and DDL permission requirements.

 - New "Write to this database" interface at ``/<database>/-/execute-write`` for running arbitrary writable SQL against mutable databases. The form extracts named parameters, analyzes the SQL, shows the table operations that will be attempted and links to a newly inserted row when a single-row insert succeeds. (:issue:`2742`)
 - Added the new :ref:`execute-write-sql <actions_execute_write_sql>` permission for running arbitrary writable SQL. Execution is also gated by table-level permissions such as :ref:`insert-row <actions_insert_row>`, :ref:`update-row <actions_update_row>` and :ref:`delete-row <actions_delete_row>`, and writes to attached databases are rejected. (:issue:`2742`)
+- The write SQL analyzer now uses a deny-by-default model for unsupported operations. Reads from source tables require :ref:`view-table <actions_view_table>` permission, schema changes require :ref:`create-table <actions_create_table>`, :ref:`alter-table <actions_alter_table>` or :ref:`drop-table <actions_drop_table>` as appropriate, and row mutation statements require the full ``insert-row``, ``update-row`` and ``delete-row`` permission set. SQL functions are allowed and are not separately permission-gated. (:issue:`2748`)
+- User-supplied write SQL now rejects ``VACUUM`` and writes to SQLite virtual tables or shadow tables. These restrictions also apply to untrusted stored write queries; trusted configured stored queries continue to skip these filters. (:issue:`2748`)

Subject: [PATCH 120/137] Use SQLiteTableType directly in SQL analysis

Remove the redundant SQLTableKind alias from the write SQL analysis model. Operation.table_kind and the analyzer cache now use the SQLite metadata classification type directly, making the source of table-kind values clearer.

Subject: [PATCH 121/137] Clarify ignored write SQL operation tests

Split the combined ignored-operation decision test into separate internal-operation and select-statement cases.

Assert the decision reason for each case instead of checking the shared base class, so the tests document why those operations are ignored.

Subject: [PATCH 124/137] datasette.yml can no longer set a query to private

Private means it has an owner, and the config does not let
you say who the owner is - plus configured queries should
not be possible to edit or delete in the UI so having an
owner makes even less sense.

You can still make configured queries visible to specific
people using regular view-query permissions.

+This page extracts named parameters from the SQL, shows the tables that will be affected and lists the permissions required before the query can be executed. It also includes templates for common ``INSERT``, ``UPDATE`` and ``DELETE`` statements.

+Datasette checks additional permissions based on the operations in the SQL. Row changes require the relevant table-level permissions such as :ref:`actions_insert_row`, :ref:`actions_update_row` and :ref:`actions_delete_row`; reads from source tables require :ref:`actions_view_table`; and schema changes require permissions such as :ref:`actions_create_table`, :ref:`actions_alter_table` or :ref:`actions_drop_table`.

 The easiest way to execute custom SQL against Datasette is through the web UI. The database index page includes a SQL editor that lets you run any SELECT query you like. You can also construct queries using the filter interface on the tables page, then click "View and edit SQL" to open that query in the custom SQL editor.
 
+For mutable databases, actors with the appropriate permissions can use the :ref:`write SQL page <pages_execute_write>` to execute SQL statements that insert, update or delete rows.
+
 Note that this interface is only available if the :ref:`actions_execute_sql` permission is allowed. See :ref:`authentication_permissions_execute_sql`.
 
 Any Datasette SQL query is reflected in the URL of the page, allowing you to bookmark them, share them with others and navigate through previous queries using your browser back button.

 - Users with :ref:`store-query <actions_store_query>` and :ref:`execute-sql <actions_execute_sql>` permission can create stored queries from the SQL query page or the new ``GET /<database>/-/queries/store`` form. (:issue:`2735`)
 - The database page now shows a count and preview of stored queries, capped at five, and links to new paginated query browsers at ``/-/queries`` and ``/<database>/-/queries``. Those browsers support search. (:issue:`2735`)
 - Stored queries created by users default to private and untrusted. Private stored queries can only be viewed, updated or deleted by their owner, even if another actor has broad ``view-query``, ``update-query`` or ``delete-query`` permission. Untrusted stored queries execute using the permissions of the actor running them. See :ref:`stored_queries` and :ref:`trusted_stored_queries` for details. (:issue:`2735`)
+- Configured queries from ``datasette.yaml`` are trusted by default, so they can execute with ``view-query`` permission alone. They can opt out of that behavior using ``is_trusted: false`` but cannot be made private; private queries are only available for user-created stored queries. (:issue:`2735`)
 - New ``store-query``, ``update-query`` and ``delete-query`` permissions, plus updated semantics for :ref:`view-query <actions_view_query>`. Trusted stored queries can still execute with ``view-query`` alone; untrusted read queries also require :ref:`execute-sql <actions_execute_sql>` and untrusted writable queries require :ref:`execute-write-sql <actions_execute_write_sql>` plus the relevant table-level write permissions. (:issue:`2735`)
 
 Write SQL UI
 ~~~~~~~~~~~~
 
-- New "Write to this database" interface at ``/<database>/-/execute-write`` for running arbitrary writable SQL against mutable databases. The form extracts named parameters, analyzes the SQL, shows the table operations that will be attempted and links to a newly inserted row when a single-row insert succeeds. (:issue:`2742`)
+- New "Write to this database" interface at ``/<database>/-/execute-write`` for running arbitrary writable SQL against mutable databases. The form extracts named parameters, analyzes the SQL, shows the table operations that will be attempted, includes starter templates for ``INSERT``, ``UPDATE`` and ``DELETE`` statements and links to a newly inserted row when a single-row insert succeeds. This is also available as a :ref:`JSON API <ExecuteWriteView>`. (:issue:`2742`)
 - Added the new :ref:`execute-write-sql <actions_execute_write_sql>` permission for running arbitrary writable SQL. Execution is also gated by table-level permissions such as :ref:`insert-row <actions_insert_row>`, :ref:`update-row <actions_update_row>` and :ref:`delete-row <actions_delete_row>`, and writes to attached databases are rejected. (:issue:`2742`)
 - The write SQL analyzer now uses a deny-by-default model for unsupported operations. Reads from source tables require :ref:`view-table <actions_view_table>` permission, schema changes require :ref:`create-table <actions_create_table>`, :ref:`alter-table <actions_alter_table>` or :ref:`drop-table <actions_drop_table>` as appropriate, and row mutation statements require the full ``insert-row``, ``update-row`` and ``delete-row`` permission set. SQL functions are allowed and are not separately permission-gated. (:issue:`2748`)
 - User-supplied write SQL now rejects ``VACUUM`` and writes to SQLite virtual tables or shadow tables. These restrictions also apply to untrusted stored write queries; trusted configured stored queries continue to skip these filters. (:issue:`2748`)

+The SQL must be writable. Read-only ``select`` queries should use the regular :ref:`custom SQL query JSON API <json_api_custom_sql>` instead.
 
 Datasette analyzes the SQL before executing it. The actor must have ``execute-write-sql`` permission for the database, and must also have any permissions required by the operations in the SQL. For example, inserts and updates against a table require ``insert-row``, ``update-row`` and ``delete-row`` permissions for that table. Reads performed as part of the write, such as ``insert into dogs select ... from other_table``, require ``view-table`` permission on the source table. Schema changes require ``create-table``, ``alter-table`` or ``drop-table`` permissions as appropriate.

-Stored queries
-~~~~~~~~~~~~~~
+Datasette now offers users with the necessary permissions the ability to both **execute write queries** against their database and to **save stored queries** (renamed from "canned queries") both privately and for use by other members of their Datasette instance.
 
-- The previous "canned queries" feature has been renamed and expanded into :ref:`stored queries <stored_queries>`. Queries configured in ``datasette.yaml`` are now loaded into a new ``queries`` table in Datasette's :ref:`internal database <internals_internal_schema>`, alongside user-created stored queries. (:issue:`2735`)
-- New stored query management APIs: ``datasette.add_query()``, ``datasette.update_query()``, ``datasette.remove_query()``, ``datasette.get_query()``, ``datasette.list_queries()`` and ``datasette.count_queries()``. These replace the removed ``datasette.get_canned_query()`` and ``datasette.get_canned_queries()`` methods. (:issue:`2735`)
-- Users with :ref:`store-query <actions_store_query>` and :ref:`execute-sql <actions_execute_sql>` permission can create stored queries from the SQL query page or the new ``GET /<database>/-/queries/store`` form. (:issue:`2735`)
-- The database page now shows a count and preview of stored queries, capped at five, and links to new paginated query browsers at ``/-/queries`` and ``/<database>/-/queries``. Those browsers support search. (:issue:`2735`)
-- Stored queries created by users default to private and untrusted. Private stored queries can only be viewed, updated or deleted by their owner, even if another actor has broad ``view-query``, ``update-query`` or ``delete-query`` permission. Untrusted stored queries execute using the permissions of the actor running them. See :ref:`stored_queries` and :ref:`trusted_stored_queries` for details. (:issue:`2735`)
-- Configured queries from ``datasette.yaml`` are trusted by default, so they can execute with ``view-query`` permission alone. They can opt out of that behavior using ``is_trusted: false`` but cannot be made private; private queries are only available for user-created stored queries. (:issue:`2735`)
-- New ``store-query``, ``update-query`` and ``delete-query`` permissions, plus updated semantics for :ref:`view-query <actions_view_query>`. Trusted stored queries can still execute with ``view-query`` alone; untrusted read queries also require :ref:`execute-sql <actions_execute_sql>` and untrusted writable queries require :ref:`execute-write-sql <actions_execute_write_sql>` plus the relevant table-level write permissions. (:issue:`2735`)
+The ability to write is controlled by the new ``execute-write-sql`` permission, but the user also needs the relevant ``insert-row``/``update-row``/``delete-row``/``create-table``/etc permissions for the query they are trying to execute.
 
 Write SQL UI
 ~~~~~~~~~~~~
@@ -26,7 +19,18 @@ Write SQL UI
 - New "Write to this database" interface at ``/<database>/-/execute-write`` for running arbitrary writable SQL against mutable databases. The form extracts named parameters, analyzes the SQL, shows the table operations that will be attempted, includes starter templates for ``INSERT``, ``UPDATE`` and ``DELETE`` statements and links to a newly inserted row when a single-row insert succeeds. This is also available as a :ref:`JSON API <ExecuteWriteView>`. (:issue:`2742`)
 - Added the new :ref:`execute-write-sql <actions_execute_write_sql>` permission for running arbitrary writable SQL. Execution is also gated by table-level permissions such as :ref:`insert-row <actions_insert_row>`, :ref:`update-row <actions_update_row>` and :ref:`delete-row <actions_delete_row>`, and writes to attached databases are rejected. (:issue:`2742`)
 - The write SQL analyzer now uses a deny-by-default model for unsupported operations. Reads from source tables require :ref:`view-table <actions_view_table>` permission, schema changes require :ref:`create-table <actions_create_table>`, :ref:`alter-table <actions_alter_table>` or :ref:`drop-table <actions_drop_table>` as appropriate, and row mutation statements require the full ``insert-row``, ``update-row`` and ``delete-row`` permission set. SQL functions are allowed and are not separately permission-gated. (:issue:`2748`)
-- User-supplied write SQL now rejects ``VACUUM`` and writes to SQLite virtual tables or shadow tables. These restrictions also apply to untrusted stored write queries; trusted configured stored queries continue to skip these filters. (:issue:`2748`)

Subject: [PATCH 133/137] Fix double-prefixed export links with base_url

Use the router-stripped route_path when building request-derived export
URLs, so table, row, and query JSON/CSV links do not apply base_url twice.

Keep urls.path() behavior unchanged, and add coverage for both /prefix/
exports and a /data/ base_url with a data database.

From b1f3e4368c81490c1468b1c641e02fa15771b013 Mon Sep 17 00:00:00 2001
From: Simon Willison <swillison@gmail.com>
Date: Sun, 31 May 2026 16:15:34 -0700
Subject: [PATCH 135/137] Fixes for SQL write with RETURNING (#2763)

* Fix for execute write returning, closes #2762
* Fix stored write returning rowcount message
* Add configurable execute_write returning limit
* Return rows/truncated from execute query if it used RETURNING
* INSERT ... RETURNING shows rows in /-/execute-write
* Skip RETURNING tests if SQLite version does not support it

+    Returns any rows buffered by Datasette from the statement, such as rows from SQLite's ``RETURNING`` clause. This may be limited by ``returning_limit`` unless ``return_all=True`` was used. This method empties the buffer, so calling it again will return an empty list.
+
+SQLite statements using ``RETURNING`` must have their rows consumed before the transaction can commit. Datasette will fetch up to ``returning_limit + 1`` rows before committing, store up to ``returning_limit`` rows on the result object and set ``.truncated`` if there were more. The default ``returning_limit`` is ``10``.
+
+When ``.truncated`` is ``True``, ``.rowcount`` will be ``-1``. SQLite only reports the final row count for a ``RETURNING`` statement after every returned row has been fetched, and Datasette has deliberately stopped fetching rows after ``returning_limit`` to avoid buffering a potentially large result in memory.
+
+If you need to retrieve every row returned by a statement, pass ``return_all=True``. This will buffer all returned rows in memory before committing.
 
 If you pass ``block=False`` this behavior changes to "fire and forget" - queries will be added to the write queue and executed in a separate thread while your code can continue to do other things. The method will return a UUID representing the queued task.

 Changelog
 =========
 
+.. _v1_0_a32:
+
+1.0a32 (2026-05-31)
+-------------------
+
+SQLite INSERT ... RETURNING clauses are now supported by ``/db/-/execute-write``, plus several fixes relating to the :ref:`base_url setting <setting_base_url>`.
+
+- ``INSERT``/``UPDATE``/``DELETE`` statements that use SQLite's ``RETURNING`` clause now work correctly in the new ``/db/-/execute-write`` interface. Datasette fetches returned rows before committing the write transaction, displays them in the HTML UI and includes them in the ``"rows"`` key for the JSON API response. (:issue:`2762`, :pr:`2763`)
+- ``Database.execute_write()`` now returns an ``ExecuteWriteResult`` object instead of the raw ``sqlite3.Cursor`` returned by ``conn.execute()``. The new object exposes ``.rowcount``, ``.lastrowid``, ``.description``, ``.truncated`` and ``.fetchall()``, and adds ``return_all=`` and ``returning_limit=`` options for controlling how rows from ``RETURNING`` statements are buffered. (:pr:`2763`)
+- Fixed the ``/-/jump`` navigation search endpoint when Datasette is served with a configured ``base_url``. (:issue:`2757`)
+- Fixed JSON and CSV export links, plus ``Link:`` alternate headers, on table, row and query pages when ``base_url`` is configured. These could previously be prefixed twice. (:issue:`2759`)
+- Fixed several other ``base_url`` handling bugs, including the API explorer form actions and share links, the ``/-/patterns`` development page, permanent redirects such as ``/-`` to ``/-/`` and database query redirects from ``/<database>?sql=...`` to ``/<database>/-/query?sql=...``.
