我有一个非常简单的问题,但我没有得到任何使用 Mysql 退出 SP 的简单代码.谁能告诉我怎么做?
I have very simple question but i did't get any simple code to exit from SP using Mysql. Can anyone share with me how to do that?
CREATE PROCEDURE SP_Reporting(IN tablename VARCHAR(20))
BEGIN
IF tablename IS NULL THEN
#Exit this stored procedure here
END IF;
#proceed the code
END;
CREATE PROCEDURE SP_Reporting(IN tablename VARCHAR(20))
proc_label:BEGIN
IF tablename IS NULL THEN
LEAVE proc_label;
END IF;
#proceed the code
END;
