Need Help With Exploding CSV Data Within DB

[eluser]Jay Logan[/eluser]
Figured it out. Here is the final code I will be using.

Code:

function unique_counties($id_name)
        {
            $this->db->select();
            $this->db->where('id_name', $id_name);
            $get_data = $this->db->get('VSS_src_network');
            $this->db->where_in('zip_code', explode(', ', $get_data->row()->addr_assoc));
            $this->db->distinct();
            $this->db->select('county_name');
            $result = $this->db->get('JL_zip_codes as County');
            return $this->clean_result($result);
        }

I have to make a new function for each item I want to be unique (city, state, etc.) but it works well. Let me know there is any better way of doing this. Thanks again.
