Notice how the statement level triggers only fire once at the start and end of the bulk insert operation, but fire on a row-by-row basis for the bulk update and delete operations.

SQL From this we can see there is a single statement level before and after timing point, regardless of how many rows the individual statement touches, as well as a row level timing point for each row touched by the statement.

SQL *** FORALL - INSERT *** BEFORE STATEMENT - INSERT BEFORE EACH ROW - INSERT (new.id=1) BEFORE EACH ROW - INSERT (new.id=2) BEFORE EACH ROW - INSERT (new.id=3) BEFORE EACH ROW - INSERT (new.id=4) BEFORE EACH ROW - INSERT (new.id=5) AFTER EACH ROW - INSERT (new.id=1) AFTER EACH ROW - INSERT (new.id=2) AFTER EACH ROW - INSERT (new.id=3) AFTER EACH ROW - INSERT (new.id=4) AFTER EACH ROW - INSERT (new.id=5) AFTER STATEMENT - INSERT *** FORALL - UPDATE *** BEFORE STATEMENT - UPDATE BEFORE EACH ROW - UPDATE (new.id=1 old.id=1) AFTER EACH ROW - UPDATE (new.id=1 old.id=1) AFTER STATEMENT - UPDATE BEFORE STATEMENT - UPDATE BEFORE EACH ROW - UPDATE (new.id=2 old.id=2) AFTER EACH ROW - UPDATE (new.id=2 old.id=2) AFTER STATEMENT - UPDATE BEFORE STATEMENT - UPDATE BEFORE EACH ROW - UPDATE (new.id=3 old.id=3) AFTER EACH ROW - UPDATE (new.id=3 old.id=3) AFTER STATEMENT - UPDATE BEFORE STATEMENT - UPDATE BEFORE EACH ROW - UPDATE (new.id=4 old.id=4) AFTER EACH ROW - UPDATE (new.id=4 old.id=4) AFTER STATEMENT - UPDATE BEFORE STATEMENT - UPDATE BEFORE EACH ROW - UPDATE (new.id=5 old.id=5) AFTER EACH ROW - UPDATE (new.id=5 old.id=5) AFTER STATEMENT - UPDATE *** FORALL - DELETE *** BEFORE STATEMENT - DELETE BEFORE EACH ROW - DELETE (old.id=1) AFTER EACH ROW - DELETE (old.id=1) AFTER STATEMENT - DELETE BEFORE STATEMENT - DELETE BEFORE EACH ROW - DELETE (old.id=2) AFTER EACH ROW - DELETE (old.id=2) AFTER STATEMENT - DELETE BEFORE STATEMENT - DELETE BEFORE EACH ROW - DELETE (old.id=3) AFTER EACH ROW - DELETE (old.id=3) AFTER STATEMENT - DELETE BEFORE STATEMENT - DELETE BEFORE EACH ROW - DELETE (old.id=4) AFTER EACH ROW - DELETE (old.id=4) AFTER STATEMENT - DELETE BEFORE STATEMENT - DELETE BEFORE EACH ROW - DELETE (old.id=5) AFTER EACH ROW - DELETE (old.id=5) AFTER STATEMENT - DELETE PL/SQL procedure successfully completed.

SQL Make sure you understand your timing points when using bulk binds or you may get unexpected results.

Row-level DML triggers are not allowed to query or perform any DML on the table that fired them.

If they attempt to do so a mutating table exception is raised.

    I hadn't realised until then that I was eligible to apply, so I spent the next few years working diligently, getting promoted, leaning to drive, researching the job (easier to do when you have a foot in the door) and just applying for every SOCO post going until they finally caved in.
