Can we use commit or rollback in trigger? If yes, then how. Please explain with a suitable example?
Answer Posted / santosh kumar
Yes ,You can Commit inside the trigger.
But for this you have to make this trigger transaction to be a Independent transaction from its parent transaction, You can do this by using Pragma. Pragma AUTONOMOUS_TRANSACTION allow you to build the Indepadent(child) Transaction,started by another. Shold be declare in DECLARE section of any subprogram.
Used to make Modular and Resuable Blocks. if you need the example then ask to me.
CREATE OR REPLACE TRIGGER TRIG_ARG
AFTER INSERT ON TAB1
DECLARE
PRAGMA AUTONOMOUNS_TRNASACTION
BEGIN
INSERT INTO LOG VALUES(SYSDATE,'INSERT ON TAB1');
COMMIT;
END;
/
OR
CREATE OR REPLACE TRIGGER t_trigger
AFTER INSERT ON t1 FOR EACH ROW
DECLARE
PRAGMA AUTONOMOUS_TRANSACTION;
i PLS_INTEGER;
BEGIN
SELECT COUNT(*)
INTO i
FROM t1;
INSERT INTO t2
VALUES
(i);
COMMIT;
END;
