      billno > 1 ORDER BY billno ASC LIMIT 1;')->result_array();
        $this->db->join('salesbill', 'salesbill.no = salesitem.billno','left 
    outer');

传递当前的帐单编号和订单（下一个/上一个）。

public function Bill_NextPrev($billNo=0,$order='next'){
   if($order='next'){
      $this->db->where('s.billno >', $billNo);
   }else{
      $this->db->where('s.billno <', $billNo);
   }
   $this->db->limit(1);
   $this->db->from('salesitem as a');

   $query = $this->db->get();
   if( $query->num_rows() == 1 ){ 
     return  $query->result();
   }
   return false;
}
