i've been trying to create an insert/update trigger on v_$session but with no success. following is my code:
1 create or replace trigger trg_module
2 instead of insert or update on t_$session
3 begin
4 delete from t_modes;
5* end;
SQL> /
Trigger created.
(t_$session is a view of sys.v_$session).
as you can see the trigger compiles ok but the code ('delete ...') is never run when there is a change in v$session. one explanations i got was that you cannot put this trigger on a view of a fixed table/view.
the reason i'm doing this is to monitor changes in v$session.module
and then execute some code. if there is another way of achieving this i would appreciate the advice.regards, Received on Thu Jun 03 2004 - 14:24:29 CEST
