Re: SQL Stored Procedure problem

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
