Parameter value differs on my procedure

[HABBIE]

Hi,
I have written a procedure, but it is not showing the proper output. As i am a beginner unable to find it out. My desired output is an set of records from a table.
this is my procedure:

CREATE PROCEDURE FIVESTAR (IN TB_SCHEMA VARCHAR(1024),IN TB_NAME VARCHAR(1024),OUT QUERY1 VARCHAR(1024))
DYNAMIC RESULT SETS 1
LANGUAGE SQL
P1: BEGIN
-- Declare cursor
DECLARE V_DYNAMIC VARCHAR(1024);
DECLARE V_SQL VARCHAR(5500);
---DECLARE TB_NAME VARCHAR(1024);
 
DECLARE cursor1 CURSOR WITH RETURN for V_DYNAMIC;
SET V_SQL = 'SELECT * FROM ' CONCAT TB_SCHEMA CONCAT '.' CONCAT TB_NAME;
 
PREPARE V_DYNAMIC FROM V_SQL;
OPEN cursor1;
FETCH cursor1 INTO QUERY1;
CLOSE cursor1;
 
-- Cursor left open for client application
--OPEN cursor1;-----
END P1

Output:

db2 => call fivestar('VENKATASD','STAFF',?);

Value of output parameters
--------------------------
Parameter Name : QUERY1
Parameter Value : 10

Return Status = 0

Please correct me , how to clear this.
