ActiveRecord class question

[eluser]i_am_using_ci[/eluser]
Hi, I wanted to ask is there any way to do query like:

Code:

update table set field = filed + 1 where id = 1

with ActiveRecord class?

I am always getting

Code:

update table set field = 'field + 1' where id = 1

when doing:

Code:

$this->db->where('id', 1);
$this->db->update('table', array('checks' = 'checks + 1'));

See the part on set in the AR user guide
Set accepts a 3rd parameter to prevent escaping things like this
