Hi,

Below is my code. This is for audit purpose. For doing a commit after insert, I included Pragma for this trigger.
But on several searches i found that there is no need of commit inside but it automatically commits..
I am bit confused by studying varyiing posts in forums..

Can somebody give me clarity on this and placement of commit in below trigger body is right ?

I am using 10g version.

CREATE OR REPLACE TRIGGER RESERVE_AUDIT
BEFORE UPDATE   ON T_COST
REFERENCING NEW AS NEW OLD AS OLD
FOR EACH ROW
DECLARE
   PRAGMA AUTONOMOUS_TRANSACTION;
BEGIN
	IF UPDATING
                THEN
   		INSERT INTO AUDIT_CONTROL 
                    		(TYPE,
                      		NO_LU_CONTROL, 
                      		CD_FACTOR, 
                 		OLD_AMT, 
                      		WHO_UPDATED,
                       		LAST_UPDATE)
   		VALUES
  	 		('RES',
  	    		:OLD.NO_LU_CONTROL,
               		 	:OLD.CD_FACTOR,
                		 :OLD.CLE_AMOUNT,
                   		 :OLD.ID_USER,
			 SYSDATE)
                END IF;
  COMMIT;	
   END RESERVE_AUDIT;

Thanks in advance
