This should work for your needs: delete from a using b where a.id = b.id -- join criteria and b.second_id = ? > I have tried to do this before and always found a way, usually > DELETE FROM a WHERE a.b_id IN (SELECT id FROM b WHERE second_id > = ?) This is akin to: delete from a where (a.key1, a.key2, a.key3) in (select key1, key2, key3 from b) I use this every day for millions of rows per delete and it works just fine and in a very reasonable time period. -Mark -- Sent via pgsql-sql mailing list (pgsql-sql@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-sql
