mysql5.5中怎样解决1329号错误

写了一个存储过程，里面用到了游标，但是执行一直报1329号错误:
Error Code : 1329
No data - zero rows fetched, selected, or processed
部分代码如下

CREATE DEFINER=`root`@`%` PROCEDURE `foreverremovestaff`()
lblexit:BEGIN 
 DECLARE p_user_type,p_user_id,p_op_type,p_op_id,delid INT;
 DECLARE p_stop INT DEFAULT 0;
 DECLARE cur_c  CURSOR  FOR SELECT id,user_type,user_id,op_type,op_id FROM corp_staff_del;
 DECLARE CONTINUE HANDLER FOR NOT FOUND,1329,SQLSTATE '02000' SET p_stop=1;
 OPEN cur_c;
 FETCH cur_c INTO delid,p_user_type,p_user_id,p_op_type,p_op_id;
 WHILE p_stop=0 DO  SELECT delid;

/*业务处理*/
  fetch cur_c into delid,p_user_type,p_user_id,p_op_type,p_op_id;
 END WHILE;
 CLOSE cur_c;
END$$

DELIMITER ;

上网查了资料，试了还是不行，请各位高手出个解决方法.
