Hello, Is there maybe an easy way to delete that player (and all his games and partners) or do I have to work with temp tables? ---/Original Message------ The easiest way is to create FOREIGN KEY relationships between the various tables and allow "ON DELETE CASCADE" to do the work. Otherwise you need to DELETE with an appropriate WHERE clause (and sub-selects) or you can use the "USING" clause with the DELETE to add additional condition tables. DELETE FROM t1 USING (t2 JOIN t3 ON (...)) t_linked WHERE t1.something = t_linked.something; See the SQL Command (DELETE) section of the documentation for more details and examples of DELETE See the SQL Command (CREATE TABLE ) section of the documentation for information on how to setup FOREIGN KEYS David J. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
