Basics:
1. Delete trigger doesn't delete the row, the DELETE command does it.
2. DELETE command invokes the delete trigger (if the trigger conditions are met).
Solution:
1. Revoke delete priv so no deleted can take place.
2. Create a before-delete trigger and raise application error so that user application receives error and transaction will rollback.

Subject: Elementary question about triggers
Dear Listers,
I hope you won't mind a question that (I think) looks unfit for this list:
"Can we prevent a delete trigger from deleting a row?"
To make it clear, here's the code for a trigger:
CREATE OR REPLACE TRIGGER temp_trig BEFORE DELETE ON temp_tab FOR EACH ROW
???
END;
What statement should I write in the PL/SQL block, that will prevent the
deletion of the row.
Thanks & regards,
Charu.
