Answer 2

$this->db->select(" i.description, i.condition,c.cat_name as category_name,i.id,(SELECT image FROM bc_item_image WHERE item_id = i.id LIMIT 1) as item_image");
$this->db->from('bc_item as i');
$this->db->join('bc_category as c', 'i.cat_id = c.id');
      $this->db->where('i.status', 1);
      $this->db->where('i.is_bartered', 0);
      $this->db->where('i.user_id','!=', $user_id);
      $this->db->where('i.is_cancel', 0);
