Split data of 1st shift and 2nd shift

Question

Hi,
I have an SSRS report that displayed the production data. It consist of data from 1st-Shift and 2nd-Shift . My SSRS has a parameter with FromDate and Todate, Time. the default date is today's date. My requirements is to
obtain the data of 1st shift and 2nd shift on the same day and displayed into one report with separate column for 1st shift and 2ns shift. The 1st shift is always start at 6:00AM and end at 2:00PM while the 2nd shift start at 2:00PM and end at 10:00PM
Btw, This report is run every hour. THe objective is to gather how the production perform.
Any help is very much appreciated. Thanks
Sample DDL
Create table #sample
(ID nvarchar(5), DateandTime datetime, qty int)
Insert into #sample(ID, dateandtime,qty) values('XXXX','2014-05-30 00:33:18.000',1)
Insert into #sample(ID, dateandtime,qty) values('TTTT','2014-05-30 05:20:57.000',1)
Insert into #sample(ID, dateandtime,qty) values('XXXX','2014-05-29 23:09:33.000',1)
Insert into #sample(ID, dateandtime,qty) values('XXXX','2014-05-30 03:45:08.000',1)
Insert into #sample(ID, dateandtime,qty) values('TTTT','2014-05-30 04:53:55.000',1)
Insert into #sample(ID, dateandtime,qty) values('XXXX','2014-05-30 06:00:06.000',1)
Insert into #sample(ID, dateandtime,qty) values('XXXX','2014-05-30 06:15:41.000',1)
Insert into #sample(ID, dateandtime,qty) values('TTTT','2014-05-30 06:07:08.000',1)
Declare @timezoneOffset int, @D1 datetime, @D2 datetime, @Stime nvarchar(8), @ETime nvarchar(8),@FromDatetime datetime, @ToDatetime datetime
Set @timezoneOffset=8
Set @D1='2014-05-30'
Set @D2='2014-05-30'
set @Stime='06:00 AM'
set @Etime='02:00 PM'
Set @FromDatetime= @D1 +''+@Stime
Set @ToDatetime= @D2 +''+@Etime
SELECT *
FROM #sample
WHERE DATEADD(HOUR,convert(int,@timezoneOffset), dateandtime) BETWEEN (@Fromdatetime) AND (@ToDatetime)

May I ask you assistance to fix this error.
i wanted this code to have a timezoneoffset. 
Also , i would like to ask if this is acceptable  in between  6:00 and 16:00, if more than 16:00 (this is 4:00PM) this would be now under shift 2. 
case when DATEPART(hour,DateandTime)
between 6 and
16 then 1
else 2 end
as shiftID,
I tried trid this but got an error:
CASE WHEN DATEADD(HOUR,convert(int,@timezoneOffset), DateandTime)
between 6 and
16 then 1
else 2 end
as shiftID2
