store procedure to transpose rows to columns

Chris Eaton created a SP to to transpose rows to columns :
Here is an example of a rowtocol stored proc that takes a SQL statement as
the first paramter, a delimiter as the second parameter and the ouput (in
the
3rd parameter) is the rows coverted to a column with the delimiter
specified
used to separate the row values.

CREATE PROCEDURE rowtocol
(IN p_slct VARCHAR(4000), IN p_dlmtr VARCHAR(4000), OUT lc_str
VARCHAR(4000))
LANGUAGE SQL
BEGIN
DECLARE SQLSTATE CHAR(5);
DECLARE lc_colval VARCHAR(4000);
DECLARE c_refcur INT;
DECLARE at_end INT DEFAULT 0;

DECLARE not_found CONDITION FOR SQLSTATE '02000';

DECLARE C1 CURSOR FOR S1;
DECLARE CONTINUE HANDLER FOR not_found SET at_end = 1;

PREPARE S1 FROM p_slct;

SET lc_str = '';
OPEN C1;
fetch_loop:
LOOP
FETCH C1 INTO lc_colval;
IF at_end = 1 THEN LEAVE fetch_loop;
END IF;
SET lc_str = lc_str || p_dlmtr || lc_colval;
END LOOP;
CLOSE C1;
END 

i have the following table:
INPUT_TABLE:

AGENT AMOUNT    PRODUCT    ORDER_ID   
----- -------------------- --------------------------------------
AA      20                 P1                  1
BB      20                 P1                  1
XX      20                  P1                  1
BB       7                  P2                  2
CC       7                  P2                  2
CC      12                 P2                  3

How to call this SP to convert input_table rows into columns?
Thank's in advance. Leny G.
