RE: Stored Procedure Questions -- RPG400-L

Nope.

Just make sure that your ODBC/OLEDB/JDBC client application closes the result set when it is done with
it.

So do you have to do anything special in order to read these then?

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

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?
