mysql - 制作 MySQL 事件时出错

Question

我有一个 MySQL 表，由于其中的信息被用于 session ，因此需要在每个午夜清空该表。 我试图在打开全局参数后创建一个 MySQL 事件，但是当我想要创建一个事件时它会给我一个语法错误。 This is the error I'm getting.

CREATE EVENT delete_messages_at_midnight 
ON SCHEDULE EVERY 1 DAY 
STARTS CURDATE() + INTERVAL 1 DAY 
DO DELETE FROM t_choices; 
delimeter;

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'delimeter' at line 4

不幸的是，由于我是新来的并且代表少于 10 个，所以我无法发布图片。

Answer 1

尝试删除后面的分号:

t_choices;

然后简单地尝试

delimiter
CREATE EVENT delete_messages_at_midnight 
   ON SCHEDULE EVERY 1 DAY STARTS CURDATE() + INTERVAL 1 DAY 
   DO DELETE FROM t_choices
delimeter ;

或者像这样:

delimiter
|
CREATE EVENT delete_messages_at_midnight 
   ON SCHEDULE EVERY 1 DAY STARTS CURDATE() + INTERVAL 1 DAY 
   DO DELETE FROM t_choices;
|
delimeter ; //Put a space between delimiter and semicolon
