Question

我通过以下查询获得了以下数据

Select *
FROM        
    (Select RP.ins_user_id, RP.Loadno, Max(RP.trndte) 'M1', Min(RP.trndte)'M2', sum(RP.trnqty) 'QTY'
                 from
                    (select R.ins_user_id,R.trnqty, R.trndte,
                        "Loadno" =
                            case when
                            R.actcod = 'sstg' then R.lodnum 
                            else R.to_lodnum
                        end
            from dbo.RP_DlyTrn R
            where R.oprcod IN ('LPCK', 'RLPCK') 
            and R.actcod in ('caspck', 'otrpck', 'palpck', 'pcepck','sstg', 'list-start')
            and R.ship_id <> 0
            and R.trndte between '08/18/2014 17:25:00' and '08/19/2014 8:00:00') RP
            where RP.Loadno is not null
            group by RP.ins_user_id, RP.Loadno) rp2
            order by RP2.ins_user_id, RP2.Loadno

结果：

ins_user_id  Loadno            end time(M1)       start time(M2)        qty   start_time suc load
