----------- without AUTONOMOUS_TRANSACTION

CREATE or REPLACE TRIGGER parts_trig

FOR EACH ROW

INSERT INTO parts_log VALUES(:new.pnum, :new.pname);
END;

INSERT INTO parts VALUES (1040, 'Head Gasket');

DECLARE

Answer / sudhir

by default Trigger doesnt allow a commit;

however we can create a stored procedure which will only do
commit.

create or replace procedure to_commit_trigger
begin
commit();

end to_commit_trigger

now execute this stored procedure to_commit_trigger inside a
trigger to perform a commit. However it will cause serious
performance issues.
