Mysql:每 10 秒删除 5 年以上的所有行 [英] Mysql: Deleting all rows older than 5 year in every 10 seconds

问题描述

我想删除 mysql 表(项目)中超过 5 年的行.

I want to delete the rows older than 5 year in mysql table(item).

item
----------------
id       neme         date_and_time
1          a          2015-04-11 11:10:04
2          b          2005-05-22 11:10:04
3          c          2007-06-21 11:10:04

我该如何做这个删除操作?

How can i doing this delete action?

我还想每 10 秒运行一次删除操作，我可以使用事件调度程序和触发器来执行此操作吗?这两个函数有什么不同?

Also I want to run this delete action in every 10 seconds, I can do this using event scheduler and trigger? What is the different for this two function?

推荐答案

尝试创建这样的事件:

CREATE EVENT DO_DELETE_OP
ON SCHEDULE
EVERY 10 SECOND
DO DELETE FROM item WHERE date_and_time < DATE_SUB(NOW(), INTERVAL 60 MONTH);
