创建存储过程：

DROP PROCEDURE mypro;
CREATE procedure mypro (sid INT,OUT sCount INT)
BEGIN

SELECT COUNT(*) INTO sCount from student where id = sid;
END

执行该存储过程：

CALL mypro(1,@c);
select @c;

创建函数：

DROP FUNCTION myfun;
CREATE FUNCTION myfun (sid INT)
RETURNS int
BEGIN
DECLARE sCount int;
SELECT COUNT(*) INTO sCount from student where id=sid;
RETURN sCount;
END

执行函数：
SELECT myfun(1)
