SQLServer分组查询相邻两条记录的时间差

--1.首先查出表中符合條件的所有信息
select IDENTITY(int,1,1) as OIndex,* into #temp1 from 操作記錄表
where OrderID in (select OrderID from 單據表 where OrderNo like 'APP%') order by OrderID,OperateDate

--2.簽核時間Delay在2~7天之內
select a.OrderID,a.OperateUser,a.OperateName into #temp2 from #temp1 a inner join #temp1 b 
on a.OrderID=b.OrderID and a.OperateUser=b.OperateUser
and a.OperateType='Receive' and b.OperateType='Send' and b.OIndex = a.OIndex+1
where datediff(dd,a.operatedate,b.operatedate)>2 and datediff(dd,a.operatedate,b.operatedate)<=7 and a.operatedate>='2012-06-10'
group by a.OrderID,a.OperateUser,a.OperateName
order by a.OrderID
--3.異常單據和異常操作人員信息
select * from #temp2
