I want to log all activity from a table to a old_table. Creating an ON INSERT trigger is simple, it just needs to INSERT INTO old_filter SELECT NEW.*; in a procedure that is called via the trigger. But what about updates? There is no simple UPDATE old_filter SET NEW.* WHERE id=NEW.id; so I would need to declare each column like UPDATE old_filter SET field1=NEW.field1,f2=NEW.f2,.... where id=NEW.id; But that is error prone, because when the "filter" table is changed to have a new column, the UPDATE statement would not contain it. Is there a fail-proof shortcut? mit freundlichen Grüßen Michael Monnerie, Ing.
