WHERE `column` = `column`

[quote author="Jamie Rumbelow" date="1273114538"]You can pass a single string to $this->db->where() and it'll work fine. So:

Code:

$this->db->where('column_a = column_b');

Well, I had to use backticks to make it work. Thanks

Code:

$where = 'product_id = `product_group`';
$this->db->where($where);
