Error when session table is updated

Well, that needs to be fixed as well, but the specific error has to do with this wrongly generated internal CI query, which would never work no matter what table it was tried on due to the tickmarks around the "less than timestamp", which isn't a field:

Code:

DELETE FROM `jaz_sessions` WHERE `last_activity` `< 1340198948`
