DELIMITER $$

CREATE PROCEDURE AddOrderItem(in orderNO int)

DECLARE EXIT HANDLER FOR SQLSTATE '01000';
DECLARE EXIT HANDLER FOR SQLSTATE '45000';

IF orderNO = 0 THEN

END IF;

END $$
DELIMITER ;

Error (while accessing through MySQL Command Line Client)suggests that MySql Signal statement does not support MySQL Server version 5.1.73. What is the solution?
