> I'm looking for a *portable* way to detect auto-incrementing primary > keys. Is there one? No - because there is no universal concept of an "auto-incrementing" primary key. MySQL and SQLite have a specific column modifier called AUTOINCREMENT. Postgres uses sequences and a default value. Oracle uses sequences and a trigger. And so on. Perhaps if you explain what exactly you are trying to do, another solution (such as $dbh->last_insert_id() perhaps?) may present itself. - -- Greg Sabino Mullane [EMAIL PROTECTED] PGP Key: 0x14964AC8 200806300940 http://biglumber.com/x/web?pk=2529DF6AB8F79407E94445B4BC9B906714964AC8 -----BEGIN PGP SIGNATURE----- iEYEAREDAAYFAkho4m0ACgkQvJuQZxSWSsiwWACg/mL+78Lhn38oJnYw3TLNeK1H jPIAn0U44fdfLuNNNXoUjnP7757Ie+7S =DhL1 -----END PGP SIGNATURE-----
