Hi, is the following the simplify? still can be more simplify?

SELECT	@a1=SUM(CASE WHEN date >=DATEADD(MONTH, +0, @startdate) and date<DATEADD(MONTH, +1, @startdate) then a else 0 END),
	@a2=SUM(CASE WHEN date >=DATEADD(MONTH, +1, @startdate) and date<DATEADD(MONTH, +2, @startdate) then a else 0 END),
	@a3=SUM(CASE WHEN date >=DATEADD(MONTH, +2, @startdate) and date<DATEADD(MONTH, +3, @startdate) then a else 0 END),
	@a4=SUM(CASE WHEN date >=DATEADD(MONTH, +3, @startdate) and date<DATEADD(MONTH, +4, @startdate) then a else 0 END),
	@a5=SUM(CASE WHEN date >=DATEADD(MONTH, +4, @startdate) and date<DATEADD(MONTH, +5, @startdate) then a else 0 END),

This?

SELECT		DATEPART(MONTH, [Date]) AS theMonth,
		SUM(a) AS a,
		SUM(b) AS b,
		SUM(c) AS c
FROM		@TempFun
WHERE		[Date] >= '20090101'
		AND [Date] < '20100101'
GROUP BY	DATEPART(MONTH, [Date])
ORDER BY	DATEPART(MONTH, [Date])

N 56°04'39.26"
E 12°55'05.63"

these will not be so messy . .


select	@a1	= sum(case when mth = 0 then a else 0 end),
	@a2	= sum(case when mth = 1 then a else 0 end),
        . . . 
	@ta	= sum(a)
        . . . 
from
(
	select	mth 	= datediff(month, @startdate, [date]),
		a	= sum(a),
		b	= sum(b),
		c	= sum(c)
	from	@Tempfun
	WHERE	[date] >= '20090101' and [date] <= '20091231'
	group by datediff(month, @startdate, [date])
) a
