RE: Stored Procedure Questions

(don't know what happened to the formatting on that first post, lets try again)

Mike,

Birgitta, gave you the answer, but let me rephrase and extend.

Unlike, MS SQL server, for an i5 stored procedure to return a results set you need to explicitly open
a cursor then end the stored procedure without closing the cursor. From the "Stored Procedures,
Triggers and User-Defined Functions on DB2 UDB for iSeries" Redbook:

CREATE PROCEDURE GetCusName()
RESULT SETS 1
LANGUAGE SQL
BEGIN
DECLARE c1 CURSOR WITH RETURN FOR
SELECT cusnam FROM customer ORDER BY cusnam;
OPEN c1;
END


Also, you don't need a dynamic SQL statement for this. Try the following:

CREATE PROCEDURE qmfiles.sp_ServiceRequestStatus (IN deptCode CHAR(5), IN divsCode CHAR(5))
LANGUAGE SQL
results sets 1
BEGIN
declare c1 cursor with return for
SELECT VCMPLNTNUM, VVLTNNUM, VCAKEY, VCAPIN, VCASTNUM, VCASTEXT,
VCASTNAME, VCASTSFX, VCASTDIR, VDTCODE, VDTCODEDSC, VDVCODE,
VDVCODEDSC, VEENAME, VCCODE, VCCODEDESC, VCDATE, VCAOWNER,
VRCODE, 1 AS SORTORDER
FROM QMFILES.NVMASTP
WHERE (VCLOSEDATE = 0)
and (divsCode = ' ' or divsCode = VDVCODE)
and (deptCode = ' ' or deptCode = VDTCODE);
open c1;
END


I highly recommend the above mentioned REDBOOK.

Last but not least, MIDRANGE-L would be a more appropriate forum for this question.

HTH,
Charles

Hi,

You need a cursor:
1. DECLARE CURSOR MyCursor Cursor for DynSQLStm; 2. Built
SQL-Statement:
Set MySQLStm = 'Select ...';
3. Konvert the String containing the SQL-Statement into an
executable SQL-Statement
Prepare DynSQLStm from MySQLStm;
4. Open the cursor and end the Procedure
Open MyCursor;

Mit freundlichen Grüßen / Best regards

Betreff: Re: Stored Procedure Questions


I have figured out part of this. I am now getting a different error.
Apparently, I can't execute a SELECT. So how do I run a
dynamically created SELECT statement?
