Hope this will help you :

You don’t need to use db_select if you have single database, if multiple database you only need to use a different database on the same connection. You can switch to a different database when you need to using this $this->db->db_select('ardefa');

You can do like this :

//$this->db->db_select('ardefa');
$this->db->select('*');
$this->db->from('borneo');
$query = $this->db->get();
if ($query->num_rows() > 0 )
{
   /*for multiple array*/

   $result = $query->result_array();
   /*print here to see the result
   print_r($result);
   */
}

Use $result like this :

foreach($result as $row)
{
    echo $row;
}

Or can also do it like this :

//$this->db->db_select('ardefa');
$query = $this->db->get('borneo');
if ($query->num_rows() > 0 )
{
   /*for multiple array*/

   $result = $query->result_array();
   /*for single array
   $row = $query->row_array();
   */
}
