UPDATE foo SET ... WHERE EXISTS (SELECT 1 FROM foo ...); INSERT INTO foo SELECT ... FROM ... WHERE NOT EXISTS (SELECT 1 FROM foo ...); The 2nd statement is executed if the first appears false. Not race-proof, and can't be, even with transactions, so be sure to execute it in a sequential manner. -- Regards, Daryl Tester "Verbogeny is one of the pleasurettes of a creatific thinkerizer." -- Peter da Silva _______________________________________________ PyGreSQL mailing list [email protected] http://mailman.vex.net/mailman/listinfo/pygresql
