Read out parameter from a stored procedure

[samhast]

I have a mysql stored procedure:

CREATE PROCEDURE `vtigercrm`.`tester` (out aantal int(255))
BEGIN
*SQL QUERY*

set @aantal = FOUND_ROWS();
select @aantal as 'Aantal';
END

I call the stored procedure:

call tester(@aantal);

Is it possible to read the out parameter in ireport?

I can't display it at the moment. Is that possbile in ireport, to display the returned result from a stored procedure?
