Question about correctly EXIT on SQL Script

Question

Hi there,
I have created a SQL script, every time when the raise_application error appears then of course the PL/SQL block ends but then still the external sql script is being executed, how can I prevent the External sql script from being executed after a raise application error is displayed?
Regards
RobH
DECLARE
BEGIN
IF start_date > stop_date
THEN
raise_application_error (-020110,
'Start Date can not be greater Stop Date. '
ELSE ..... do some selecting and inserting of data into temporary tables etc...
END IF;
END;
--And now a external SQL script should be started...

Answer 1

you can trap your exception in the inner block using EXCEPTION block and from there propagate it to the external block to stop further processing. something like this...
DECLARE
  l_deptno NUMBER;
BEGIN
  FOR i IN (SELECT deptno FROM dept)
  LOOP
    BEGIN
      FOR j IN (SELECT empno, ename FROM emp WHERE deptno = i.deptno)
      LOOP
        IF ( i.deptno = 20 ) THEN
          RAISE_APPLICATION_ERROR(-20001, 'Error Raised');
        ELSE
          DBMS_OUTPUT.PUT_LINE('Dept = ' || i.deptno || ' EmpNo: ' || j.empno || ' EName: ' || j.ename);
        END IF;
      END LOOP;
    EXCEPTION
      WHEN OTHERS THEN
        DBMS_OUTPUT.PUT_LINE('Error Trapped Inside');
        RAISE;
    END;
  END LOOP;
EXCEPTION
  WHEN OTHERS THEN
    DBMS_OUTPUT.PUT_LINE('Error Trapped Outside');
END;
