so users_has_cards has a check ( total >= decks + auctions ) and decks_has_cards needs triggers on insert, update, and delete that manipulate the decks column of the users_has_cards record that corresponds to that card. This is probably goiung to make updates to the decks_has_cards table about 10 times slower (should still be faster than you could have done in PHP) -- ⚂⚃ 100% natural -- Sent via pgsql-sql mailing list (pgsql-sql@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-sql
