You should look at datepart.For example, 2012-04-03 is in the fifteenth week of the year so if that date appears then the week number 15 should appear along side it.
You sure about that? I believe it is in the 14th week.
select DATEPART(ww, '2012-04-03')
Possibly, doesn't really matter what the week number is as long as it is the correct one.
OK so to borrow from Cadavre's post...
SELECT [YEAR] = YEAR(startup_Time),
DATEPART(ww, startup_Time) as WeekNumber,
[MONTH_NUMBER] = DENSE_RANK() OVER(ORDER BY DATEADD(MONTH, DATEDIFF(MONTH, 0, startup_Time), 0)),
startup_Time
FROM #KWHtemp;
