RE: :new and :old

Hi,


Yes i am trying to create a trigger that track changest made on employee_tbl.Our database is created in such a way that all the table and fieldname that need to be track will be stored in AUDITTABFLD table. This audit table field contains , tablename and fieldname that needs to be audited.

If the trigger is triggered by a INSERT/UPDATE statement on employee_tbl , then it will read audittabfld.To see if this table needs to be audited. If in this case, the table existed in AUDITTABFLD then the trigger will have to retrieve all the fieldname to be audited, and log all the field name before and after value into EMPLOYEE_LOG_TBL. So in my triggers i have created a cursor to read the fieldname and then loop the statement.

I encounter some problem in assigning the OLD and NEW value. Error will occur then i tried to do this :OLD.<fieldname> :NEW.<fieldname>

Since the cur1 will return more than one value , then i need it to be dynamic.

I hope you can understand what i am trying to explain here.:)

THANK YOU
JKEAN

am trying to refer :OLD.
:NEW. from the cursor. I got an

Declare
CURSOR cur1 IS
SELECT FIELDNAME=20
FROM TRACKFLD=20
WHERE TRACKTABLENAME =3D 'COMPANY_MASTER'

Begin
FOR cur1_rec IN cur1

LOOP

INSERT INTO AUDITLOG =20
(FIELDNAME,AUDITBEFOREVALUE,AUDITAFTERVALUE)=20
=20
VALUES
(:FIELDNAME,:OLD.cur1_rec.FIELDNAME,:NEW.cur1_rec.FIELDNAME);
=20
END LOOP;
=20
