So there are two sides to supporting this:

  • Being able to sensibly introspect composite foreign keys
  • Being able to define composite foreign keys when creating a table

Here's what's missing: In [11]: db.conn.execute('PRAGMA foreign_key_list(song)').fetchall() Out[11]: [(0, 0, 'album', 'songartist', 'albumartist', 'NO ACTION', 'NO ACTION', 'NONE'), (0, 1, 'album', 'songalbum', 'albumname', 'NO ACTION', 'NO ACTION', 'NONE')] Compare with this code here: https://github.com/simonw/sqlite-utils/blob/d0cdaaaf00249230e847be3a3b393ee2689fbfe4/sqlite_utils/db.py#L563-L579

The first two columns returned by PRAGMA foreign_key_list(table) are id and seq - these show when two foreign key records are part of the same compound foreign key. sqlite-utils entirely ignores those at the moment.
