MySQL Query Browser下创建存储过程和自定义函数

写MySQL，写了两个简单的

简单的存储过程：

DELIMITER $$
DROP PROCEDURE IF EXISTS wy_proc $$
CREATE PROCEDURE wy_proc (IN tname varchar(50),out outvalue datetime)
begin
set outvalue = CAST('1858-11-17' as datetime);
select outvalue;
END $$
DELIMITER ;

简单的函数：

DELIMITER $$
DROP FUNCTION IF EXISTS wy_fun $$
CREATE FUNCTION wy_fun (num varchar(50)) RETURNS datetime
begin
declare outvalue datetime;
set outvalue = CAST('1858-11-17' as datetime);
RETURN outvalue;
END $$
DELIMITER ;
