Query should be changed - sql

Question

I have one query this query display will be based on the day which day the hours is there based on the week it will display.
In this hours table my start date and end date starts from 2014-01-06 2014-01-12 one week..
for eg:
declare #Hours as Table ( EmpId Int, Monday Time, Tuesday Time, Wednesday Time,
Thursday Time, Friday Time, Saturday Time, Sunday Time, StartDate Date, EndDate Date );
insert into #Hours
( EmpId, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday, StartDate, EndDate )
values
( 1, '08:00', '00:00', '00:00', '00:00', '00:00', '00:00', '00:00', '2014-01-06 00:00:00.000', '2014-01-12 00:00:00.000' );
select * from #Hours;
with Week as (
-- Build a table of all of the dates in the work week.
select StartDate as WorkDate, EndDate
from #Hours
union all
select DateAdd( day, 1, WorkDate ), EndDate
from Week
where WorkDate < EndDate ),
DaysHours as (
-- Build a table of the hours assigned to each date.
select EmpId,
case DatePart( weekday, W.WorkDate )
when 1 then H.Monday
when 2 then H.Tuesday
when 3 then H.Wednesday
when 4 then H.Thursday
when 5 then H.Friday
when 6 then H.Saturday
when 7 then H.Sunday
end as Hours,
WorkDate as StartDate, WorkDate as EndDate
from Week as W inner join
#Hours as H on H.StartDate <= W.WorkDate and W.WorkDate <= H.EndDate )
-- Output the non-zero hours.
select EmpId, Hours,StartDate as StartDate, EndDate
from DaysHours
where Hours <> Cast( '00:00' as Time );
need the output like this:
EmpId Hours StartDate EndDate
----------- ---------------- ---------- ----------
1 08:00:00.0000000 2014-01-06 2014-01-06
because monday only we have the value.but my output like this
EmpId Hours StartDate EndDate
----------- ---------------- ---------- ----------
1 08:00:00.0000000 2014-01-12 2014-01-12
it should work based on which day the value is there.
Can any body alter in this query itself.
Thanks,

Try this query:
SELECT x.EmpId, ca.Hours, ca.CurrentDate AS StartDate, ca.CurrentDate AS EndDate
FROM #Hours x
CROSS APPLY
(
SELECT y.Hours, DATEADD(DAY, y.NumOfDays, x.StartDate)
FROM
(
SELECT x.Monday, 0
UNION ALL SELECT x.Tuesday, 1
UNION ALL SELECT x.Wednesday, 2
UNION ALL SELECT x.Thursday, 3
UNION ALL SELECT x.Friday, 4
UNION ALL SELECT x.Saturday, 5
UNION ALL SELECT x.Sunday, 6
) y (Hours, NumOfDays)
WHERE y.Hours <> '00:00:00.0000000'
) ca (Hours, CurrentDate);
