SQL & PL/SQL

Hi All,
I wrote an program..I have doubt whether i can use if condition in FORALL INSERT OR BULK COLLECT? I can't go for 'for loop' ....Is there any way to to do validations in FORALL INSERT and BULK COLLECT like we do in 'for loop' ...

create or replace
PROCEDURE name AS
CURSOR CUR_name IS

SELECT OLD_name,NEW_name FROM DIRECTORY_LISTING_AUDIT;

TYPE V_OLD_name IS TABLE OF DIRECTORY_LISTING_AUDIT.OLD_name%TYPE;
Z_V_OLD_name V_OLD_name ;


TYPE V_NEW_name IS TABLE OF DIRECTORY_LISTING_AUDIT.NEW_name%TYPE;
Z_V_NEW_name V_NEW_name ;

BEGIN

OPEN CUR_name ;
LOOP
FETCH CUR_name BULK COLLECT INTO Z_V_OLD_name,Z_V_NEW_name;

IF Z_V_NEW_name <> NULL THEN
Z_V_OLD_name := Z_V_NEW_name ;
Z_V_NEW_name := NULL;
END IF;

FORALL I IN Z_V_NEW_name.COUNT


INSERT INTO TEMP_DIREC_AUDIT (OLD_name,NEW_name) VALUES (Z_V_OLD_name(I),Z_V_NEW_name(I));

EXIT WHEN CUR_name%NOTFOUND;
END LOOP;
CLOSE CUR_name;
END name;
