Question

我是mysql存储过程的新手。我一直试图通过我在下面创建的商店程序插入数据。该过程确实返回@USER_ID。但是，该过程不会将数据插入表中。

感谢任何人可以提供帮助。提前谢谢。

Answer 1

首先：你所做的事情本质上是错误的。

INSERT INTO SEQ_USR_PROFILE_USER_ID(ID) VALUES (NULL);和SELECT @USER_ID := MAX(ID) FROM SEQ_USR_PROFILE_USER_ID;之间存在竞争条件，最终可能会使用wromng用户ID。
使用SELECT LAST_INSERT_ID();可以避免
使用交易也可以避免

现在代码：第一眼就是CURRENT_TIMESTAMP是一个函数，所以你需要写CURRENT_TIMESTAMP()。

我还建议删除序列表并直接在用户表上使用AUTO_INCREMENT，并通过SELECT LAST_INSERT_ID();轻松返回ID

Answer 2

SELECT @USER_ID := MAX(ID) FROM SEQ_USR_PROFILE

是你的第一线吗？无论insert语句的返回（甚至是否存在），您的函数都将返回该函数

尽管返回ID为
