Hi.

This is the table output I have while using SELECT.

Now I want to DELETE all records , except those from the last 3 hours.

I tried mysql combined with now() and I tried this:

SELECT * FROM `my_tab` WHERE SEC_TO_TIME(-10800) > `created_on` 

 If someone can give the right setup how to do this in PHP/MYSQL then I would be very happy.

You can use the condition `created_on` < DATE_SUB(NOW(), INTERVAL 3 HOUR). It uses the DATE_SUB() function.
