$query=$this->db->select('*') ->from('activation') ->join('products','products.id_pro = activation.id_pro') ->join('user','user.id = products.user_p') ->order_by('id_key','DESC') ->get();
return $query->result();
I have these code where I join result from 3 tables abd that works good. What I need more is counted rows from 4.table. That table is called license, and I need to count how many rows are with id_key (primary key for table activation). How to add that in my code?
