Answer Posted / ddrema
It's posible and mandatory if you use AUTONOMOUS
TRANSACTION in the TRIGGER.
like this:
CREATE OR REPLACE TRIGGER audit_sal
BEFORE UPDATE OF salary ON employees FOR EACH ROW
DECLARE
PRAGMA AUTONOMOUS_TRANSACTION;
BEGIN
INSERT INTO emp_audit VALUES( :old.employee_id, SYSDATE,
:new.salary, :old.salary );
COMMIT;
END;
