Hi! I have a trigger that when you update a value on a table, makes an insert into another table. The trigger looks like the following: BEGIN set datestyle to 'sql'; set datestyle to 'european'; IF (TG_OP = 'UPDATE' and (OLD.situation!=NEW.situation)) THEN INSERT INTO table_B VALUES (OLD.id,NEW.situation,NOW()); END IF; RETURN NULL; END; For exemple, If I do the next querys: --> update table_A set situation='Started' where id='23'; On table_A appears: id | situation --------+----------- 23 | Started On table_B appears: id | situation | when --------+-----------+--------------------- 23 | Started | 2013-03-08 12:33:35 --> update table_A set situation='Waiting' where id='23'; On table_A appears: id | situation --------+----------- 23 | Waiting On table_B appears: id | situation | when --------+-----------+--------------------- 23 | Started | 2013-03-08 12:33:35 23 | Started | 2013-03-08 12:33:37 I don't understand why after the second update, the insert done on table_B is incorrect, and has the same values that the first one. I've been looking for some kind of explanation like cache or something, but I couldn't find anything. Thanks in advance.
