20:27:34	call new_procedure(20150112)	Error Code: 1318. Incorrect number of arguments for PROCEDURE company.new_procedure; expected 2, got 1	0.000 sec

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;
