统计SQL

WITH(NOLOCK)用法
select * from(
SELECT  
case sa.ActivityTimeType 
when 1 then sc.EndDate
else sa.EndDate
end as EndDate,
 sa.BeginDate,
si.Sort,
case si.SeckillItemsType
when 1 then ii.ItemStatus
when 2 then  '1'
end as ItemStatus,
si.ItemCount,
si.SaleVolume 
FROM SeckillItems si WITH(NOLOCK)
JOIN SeckillActivitys sa WITH(NOLOCK) ON si.ActivityNo = sa.ActivityNo AND si.CustId = sa.CustId
left JOIN ItemInfo ii WITH(NOLOCK) ON si.ObjItemNo = ii.ItemNo AND si.CustId = ii.CustId and ii.ItemType = 3
left JOIN TicketCls tc WITH(NOLOCK) ON si.ObjItemNo = tc.TicketClsNo AND si.CustId = tc.CustId 
left join SeckillActivityCycle sc WITH(NOLOCK) on sa.CustId=sc.CustId and sa.ActivityNo=sc.ActivityNo
