在特定时间内自动从数据库中删除数据 [英] Remove data from database automatically at particular amount of time

问题描述

我正在开发一个应用程序，其中我有3列（id，name和date）的表。



现在在日期字段中我存储了用户加入的日期，但现在我要删除超过4天的用户记录，从最初的加入日期开始。





我想要这样的东西......

日期字段有条目4/6 / 2013

现在4天后，即2013年8月6日所有具有4/6/2013日期的记录将自动删除...这应该自动完成..让我们说当服务器时间到了凌晨12:00它应该自动发生......我怎样才能做到这一点？

请帮帮我..？



提前致谢。

I am developing an application in which i have table with 3 columns (id, name and date).

Now in date field I am storing date the user joined, but now i want to delete the user records which are over 4 days old, from the original date of joining.


I want something like this...
there is entry on date field 4/6/2013
Now after 4 days i.e. on 8/6/2013 all the records having 4/6/2013 date will be removed autometically... This should be done automatically.. Lets say when the server time gets 12:00AM it should be happen automatically... How can i achieve this?
Please help me out..?

Thanks in advance.
