Question

I have a datetime column called ‘last_login’.

I want to query my database to select all records that haven’t logged in within the last month. How do I do this?

This is what I have currently:

$query = $this->query("SELECT u.id, u.name, u.email, u.registered, g.name as group_name FROM `:@users` AS u LEFT JOIN `:@groups` AS g on u.group_id = g.id WHERE u.last_login = ...... LIMIT {$limit_start}, {$limit_end}");

:@ = database prefix

Answer 1

Try using date_sub

where u.last_login < date_sub(now(), interval 1 month)

(Similar to the first answer but in my mind it is more "natural" to use positive integers)
