Re: SQL Stored Procedure problem

[John McKee <jmmckee@xxxxxxxxxxxxxx>]

I have no experience with stored procedures.  So, I am curious why you are
setting Last_Rec to 'Y'.  I would have set it to 'N'.  I do know how Last_Rec
is to get a new value.  But, starting wiyth it as 'Y' look wrong.

Hello Everyone,

   I'm having problem trying to write my 1st SQL Stored Procedure, and I
thought I would post my problem here, and see if someone could help.  I'm
trying to read a DB2 table, and update a second table based on a value in the
1st table.  When I run the SQL stored procedure it appears to only read one
record, and then it leaves the loop.  Here is my code.

CREATE PROCEDURE UPDMHGPI
   LANGUAGE SQL
   MODIFIES SQL DATA
   BEGIN
     DECLARE GPI CHAR(14);
     DECLARE NEWGPI CHAR(14);
     DECLARE Last_Rec CHAR(1);
     DECLARE C1 CURSOR FOR SELECT FGPI, FNEWGPI FROM FACTS;
     DECLARE CONTINUE HANDLER FOR NOT FOUND
     SET Last_Rec = 'Y';
     OPEN C1;
     FETCH_LOOP:
     LOOP
      FETCH C1 INTO GPI, NEWGPI;
      IF Last_Rec = 'Y' THEN
       LEAVE FETCH_LOOP;
      END IF;
      UPDATE EMRMEDS SET MDMEDGPI = NEWGPI
       WHERE MDMEDGPI = GPI;
     END LOOP FETCH_LOOP;
     CLOSE C1;
   END

I wrote this stored procedure based on an example I found in the book I have
called "SQL for eServer i5 and iSeries" by Kevin Forsythe.  Can anyone tell me
where I've gone wrong?

Sincerely,
Michael Soucy
