I am trying to use the following trigger: CREATE TRIGGER formatname BEFORE update OR insert ON mytable FOR EACH row EXECUTE PROCEDURE lower(name); however, it gives me the message: ERROR: CreateTrigger: function lower() does not exist obviously this does exist, since I can do inserts/updates/selects using lower(). I have also tried creating my own version of a lower function but it gives me the same message. Am I missing something? This seems like it should be pretty straightforward. tia, robert ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
