How to add the update statement in this procedure?

Question

I have one table usersubscription (userid,newsletterid,deleted)
I got one string from user e.g. ('1,2,3') and userid = 14
I wrote proceduer that will insert this records in to usersubscription table;
userid     newsletterid     deleted
14     1          n
14     2          n
14     3          n
default value of deleted column is 'n'.
my procedure is as follows;
CREATE OR REPLACE PROCEDURE usersubscription_procd1 (vuserid in number, vnewsletterid IN VARCHAR2)
AS
I NUMBER;
J NUMBER;
VAL VARCHAR2(100);
BEGIN
     I := 1;
     J := 1;
     WHILE INSTR(vnewsletterid,',',I) != 0 LOOP
     VAL := SUBSTR(vnewsletterid,I,INSTR(vnewsletterid,',',I)-J);
     I := INSTR(vnewsletterid,',',I)+1;
     J := I;
     INSERT INTO usersubscription (usersubcriptionid,userid,newsletterid)
     VALUES (usersubscription_seq.nextval,vuserid,VAL);
     END LOOP;
     VAL := SUBSTR(vnewsletterid,I,LENGTH(vnewsletterid));
     INSERT INTO usersubscription (usersubcriptionid,userid,newsletterid)
     VALUES (usersubscription_seq.nextval,vuserid,VAL);
END;
Now one requirement is that when new string comes for same userid e.g.('1,4,5') userid = 14
then the deleted column for 1 and 2 newsletterid changes to 'y';
please tell me the solution.

Hi,
Before your loop, you can make something else like :
SQL> select * from test;
    USERID NEWSLETTERID D
        14            1 n
        14            2 n
        14            3 n
SQL> update test
  2  set deleted = 'y'
  3  where instr('1,4,5',newsletterid,1) = 0
  4  and userid = 14;
2 ligne(s) mise(s) à jour.
SQL> select * from test;
    USERID NEWSLETTERID D
        14            1 n
        14            2 y
        14            3 y
SQL> HTH,
Nicolas.
