Just want to select distinct values from db using codeigniter but it returns duplicate values. Could you please check what is wrong with my code below:

$this->db->distinct('country');
$this->db->where('id',$id);
$query = $this->db->get('table_name');

$this->db->distinct();
$this->db->select('country');
