In the short term, I suggest you add something to the documentation showing how to always enable this using a callback. Something like my $enable_fks = sub { shift->do('PRAGMA foreign_keys = ON') }; my $dbh = DBI->connect($dsn, '', '', { Callbacks => { connect => $enable_fks, }, }); If the user uses connect_cached, she should use this instead: Callbacks => { 'connect_cached.reused' => $enable_fks, }, Longer term, it'd be ideal if there was a database handle attribute one could set to turn this on: $dbh->{sqlite_foreign_keys} = 1; It's be useable in connect() too, of course. Is there a C api call to do this, so you could bypass the PRAGMA SQL call? Best, David
