Mysql while loop example


Hi Guys using this example from
http://www.tutcity.com/view/getting-started-with-mysql-stored-procedures.23562.html

This is my while loop example,

DELIMITER $$
DROP PROCEDURE IF EXISTS `SBCloop` $$
CREATE PROCEDURE `SBCloop`()
BEGIN
      DECLARE x INT;
      DECLARE str VARCHAR(255);
      SET x = 1;
      SET str = '';
                    WHILE x <= 5 DO
                    SET str = CONCAT(str,x,',');
                    SET x =x;
      END WHILE;
      SELECT str;
    END$$
DELIMITER;

> Query returned no resultset;


CALL `SBCloop`()
This hangs the query for 10 + minutes so i have to close the connection through Mysql administrator and kill thread.


Where have I done wrong?
Thanks guys
