Hi,
Assume you have EMP block (source is EMP table) and EMPNO is the queryble item. After retrieving record(s), if the user changes EMPNO of any retrieved record then all other fields should be cleared automatically.
Use the following code in WHEN-VALIDATE-ITEM trigger of EMPNO field to satisfy the above condition.
DECLARE
V_EMPNO NUMBER(4):=NULL;
BEGIN
IF :SYSTEM.RECORD_STATUS = 'CHANGED' THEN
IF GET_ITEM_PROPERTY('EMP.EMPNO', DATABASE_VALUE) <> :EMP.EMPNO THEN
:EMP.ENAME := NULL;
:EMP.JOB := NULL;
:EMP.MGR := NULL;
:EMP.HIREDATE := NULL;
:EMP.SAL := NULL;
:EMP.COMM := NULL;
:EMP.DEPTNO := NULL;
END IF;
END IF;
END;
