2、错误原因

CREATE DEFINER=`root`@`localhost` PROCEDURE `new_procedure`(in `departId` int,out `num` int)
BEGIN

  select count(t.depart_name) into num from t_department_info t where t.depart_id = departId;

END

call new_procedure(20150112);

在调用存储过程中，须要传入两个參数，可是仅仅传了一个參数

3、解决的方法

call new_procedure(20150112,@num);
