I have a table named ChatSessions where I keep track of active users in the chatroom. I need to prune expired user sessions from the table every 10 minutes. Using pure php-mysql is plain simple but I'm totally clueless how to convert this into ActiveRecord in CodeIgniter. The plain SQL query is below:

SELECT *
FROM `ChatSessions`
WHERE `SessionExpires` < DATE_SUB( NOW( ) , INTERVAL 10 MINUTE )

Can anybody tell me what is the equivalent code in CodeIgniter using ActiveRecord?

Thanks in advanced.
