Comments for Mutating Table Exceptions
Fabrizio Sitzia said...Excellent article!
It helped me understand, and solve, a similar mutating table problem which was caused by cascaded deletes.
Ernesto Serravalle said...This article helped me to save a lot of time I would have to waste redesigning a new solution to avoid mutating tables error.
Thank you very much!

Raj said...Excellent !!
This was not exactly the problem i was facing, but it opened my eyes to a fact that what is mutating within a ROW level trigger may not be mutating in a STATEMENT level trigger.
Hats Off :)

Srikanth said...What happens one one insert statement inserts multiple rows? The row account in the audit table wont be accurate. It will reflect the row account at the end of insert stamenet instead of for each row that was inserted.
Mike G. said...Hi:
Great article! I just have one question. Why was the SELECT COUNT(*) put INSIDE the FOR loop in the following procedure?
PROCEDURE tab1_statement_change IS
FOR i IN g_change_tab.first ..g_change_tab.last LOOP
INSERT INTO tab1_audit (id, action, tab1_id, record_count, created_time)
VALUES (tab1_audit_seq.NEXTVAL, g_change_tab(i).action, g_change_tab(i).id, l_count, SYSTIMESTAMP);
I just want to confirm that by the time we get to this statement level trigger, count(*) will always return the same number every time through the loop, correct? Therefore we only need to do it before entering the loop.
