Running queries

You can run SQL queries against a Datasette instance like this:

dclient query https://latest.datasette.io/fixtures "select * from facetable limit 1"

Output:

[
  {
    "pk": 1,
    "created": "2019-01-14 08:00:00",
    "planet_int": 1,
    "on_earth": 1,
    "state": "CA",
    "_city_id": 1,
    "_neighborhood": "Mission",
    "tags": "[\"tag1\", \"tag2\"]",
    "complex_array": "[{\"foo\": \"bar\"}]",
    "distinct_some_null": "one",
    "n": "n1"
  }
]

Output formats

Query results default to JSON. Use these flags for other formats:

  • --csv — CSV
  • --tsv — TSV
  • --nl — Newline-delimited JSON (one JSON object per line)
  • --table — Formatted text table
dclient query https://latest.datasette.io/fixtures \
  "select state, count(*) as n from facetable group by state" --table

Output:

state  n
-----  --
CA     10
MI     4
MO     1

Export as CSV:

dclient query https://latest.datasette.io/fixtures \
  "select * from facetable limit 5" --csv > results.csv
