Question

I would like to list members which have not logged in within 90 days. In mysql I have a
last_access column which updates every time a user logs in. So i think the check can be performed on this column. The columns format is: date("Y/m/d : H:i:s", time()) (2011/05/10 : 21:42:33)

What would be an appropriate SQL query to use?

Answer 1

SELECT username
FROM users
WHERE DATEDIFF(NOW(),last_access)>90
