Listing indexes
===============
The ``indexes`` command lists any indexes configured for the database::
$ sqlite-utils indexes covid.db --table
table index_name seqno cid name desc coll key
-------------------------------- ------------------------------------------------------ ------- ----- ----------------- ------ ------ -----
johns_hopkins_csse_daily_reports idx_johns_hopkins_csse_daily_reports_combined_key 0 12 combined_key 0 BINARY 1
johns_hopkins_csse_daily_reports idx_johns_hopkins_csse_daily_reports_country_or_region 0 1 country_or_region 0 BINARY 1
johns_hopkins_csse_daily_reports idx_johns_hopkins_csse_daily_reports_province_or_state 0 2 province_or_state 0 BINARY 1
johns_hopkins_csse_daily_reports idx_johns_hopkins_csse_daily_reports_day 0 0 day 0 BINARY 1
ny_times_us_counties idx_ny_times_us_counties_date 0 0 date 1 BINARY 1
ny_times_us_counties idx_ny_times_us_counties_fips 0 3 fips 0 BINARY 1
ny_times_us_counties idx_ny_times_us_counties_county 0 1 county 0 BINARY 1
ny_times_us_counties idx_ny_times_us_counties_state 0 2 state 0 BINARY 1
It shows indexes across all tables. To see indexes for specific tables, list those after the database::
$ sqlite-utils indexes covid.db johns_hopkins_csse_daily_reports --table
The command defaults to only showing the columns that are explicitly part of the index. To also include auxiliary columns use the ``--aux`` option - these columns will be listed with a ``key`` of ``0``.
The command takes the same format options as the ``tables`` and ``views`` commands.
