Active Record trouble

[eluser]nEJC[/eluser]
I've just run into this same problem. This

Code:

$this->db->where('mc.section_id=s.id');

and

Code:

$this->db->where('mc.section_id','s.id');

both returned empty resultset. But the following works

Code:

$this->db->where('mc.section_id = s.id');

Notice extra spaces around equals sign.

I wonder would this be listed as a bug or feature? If its a feature it should probably be mentioned in documentation...
