insert into #batchdata select * from Batch_1 order by timestamp desc

declare @query varchar(500)
declare @starttime datetime
declare @endtime datetime
declare @subsequenttag varchar(50)
set @starttime=(select min(timestamp) from #batchdata where value=@batch)

declare @subsequentcount int
set @subsequentcount=(select count(*) from #batchdata where timestamp>@starttime)

if (@subsequentcount =0)
begin
	select @endtime=getdate()
end
else
begin
	select @endtime=min(timestamp) from #batchdata where value!=@batch and timestamp>@starttime
end
select @starttime as starttime, @endtime as endtime
declare @stime varchar(20)
