Question

Although I have been working with PHP for a while, the one part of it I am still trying to get right is time.

I am creating a simple script that will check if the timestamp is greater than or equal to an hour, and if it is, it will be deleted from the database.

2013-01-03 20:30:25

DELETE FROM tablename WHERE timestamp = ?????

I am not sure how to execute the query to delete values with a timestamp of over an hour from the current time. Any help is greatly appreciated.

Answer 1

DELETE FROM tablename WHERE `timestmap` < DATE_SUB(NOW(), INTERVAL 1 HOUR)
