Stored Procedure - Aliases problem

[Marco Vasquez]

Currently, we are using the next tool in order to execute SQL commands
in DB2 databases:

About DB2 Administration Tools Environment
--------------------------------------------------------------------
DB2 administration tools level:
Product identifier SQL08020
Level identifier 03010106
Level DB2 v8.1.7.445
Build level s040812
PTF WR21342
--------------------------------------------------------------------
Java development kit (JDK):

We used the following Stored Procedure:

CREATE PROCEDURE SPU_TEST()
LANGUAGE SQL
DYNAMIC RESULT SETS 1
NOT DETERMINISTIC
CALLED ON NULL INPUT
MODIFIES SQL DATA
BEGIN
DECLARE Temp_Cursor CURSOR WITH RETURN FOR
SELECT
PLANT_CODE AS CODE,
NAME AS PLANT_NAME
FROM
PLANT;

OPEN Temp_Cursor;
END
¡
CALL SPU_TEST()
¡

In the following environment, the above stored procedure works without
problems.

Target Type = DB2 UDB for Linux, UNIX and Windows Database
Database Server = DB2/NT 8.2.0

CODE PLANT_NAME
01 plant1
02 plant2
.... ...
However, when we tested the same stored procedure in the following
environment, the aliases names for the columns are not showed.

Target Type = DB2 UDB for z/OS Subsystem
Database server = OS/400 5.3.0

PLANT_CODE NAME
01 plant1
02 plant2
.... ...
What's the problem?
