            $item['loglist'] = Db::name('merchant_order_detail_log')->where("order_detail_id=".$item['id']." and amount>0")->field('order_sn')->select();            return $item;
        });

$list = Db::name('merchant_order')->alias('a')
                ->join('merchant_member mm', 'mm.id=a.member_id', 'LEFT')
