时间戳过期时，从数据库中删除登录数据MySQL

Question

I have this database:

login_id -> AI, INT, PK
login_token -> VARCHAR(255)
login_userId -> VARCHAR(255)
login_expires -> VARCHAR(255)

login_expires is a UNIX timestamp.

The login_token will be bound to a cookie. When the cookie expires, the row from the database with the login_token from the cookie should be deleted too.

What's the easiest why to do this?

Answer 1

With MySQL >= 5.1 you can use an event scheduler:

CREATE EVENT expired
ON SCHEDULE AT CURRENT_TIMESTAMP + INTERVAL 5 MINUTES
DO
   DELETE FROM your_table
   WHERE login_expires < NOW();
