Quick question regarding where_in/where_not_in Active Record

[eluser]Armchair Samurai[/eluser]
Unlike where(), you can't add FALSE as a third parameter to prevent the escaping of variables (unless it's an undocumented feature - I haven't checked the source) with where_not_in(), so best to write out the subquery if you use AR.

Code:

$this->db->where('table.id NOT IN', '(SELECT other.id FROM other)', FALSE);
