I have a query that returns data with a total amount


declare @Value int
set @Value = 10000

SELECT 	cust_name,
	costcent,
	SUM(Invoices.amount) AS amount, 
	SUM(
	CASE 
		WHEN	amount < totamnt AND totamnt = promamt
		THEN	amount
		ELSE  	PromAmt
	END	)AS AmountPromised
FROM 	Invoices 
WHERE Invoices.PaidFlag = 0
GROUP BY cust_name, costcent
HAVING SUM(Invoices.amount) >= @Value
ORDER BY cust_name, costcent

Retunrs data as


3 HARDMAN SQUARE RETAIL LIMITED	ZMCR	11045.0000	11045.0000
A-ONE+	ZCIN	899553.9000	NULL
A1 MOBIL KONSORTIUM	ZDTI	23269.0300	NULL
ACCIONA	ZDTI	11896.8800	NULL

Now, the amount is a total promised amount for a load of invoices.
I need to add the actual month the amount was promised as a separate column:


select datename(month, promamtdate), datename(year, promamtdate) from invoices where promamtdate is not null

So, I would get:


cust_name, costcent, amount, AmountPromised, Nov 2007, Dec 2007, Jan 2008, Feb 2008, March 2008, April 2008, June 2008, etc.

I guess the columns need to be dynamic.

Any ideas on how to do this?
Could I do it with a case statement or am I going to have to create a temporary table?

How many columns will you need to show? six months forward always?

Well, it has to be somewhat dynamic. It could be whatever is in the tables, usually 6 months back, 3 months forward.
However, I would be able to get hold of a distinct list using the SQL:


select datename(month, promamtdate), datename(year, promamtdate) from invoices where promamtdate is not null
group by datename(month, promamtdate), datename(year, promamtdate)

I think this should give you a start:

I have tried one of those crosstab queries but the part giving me problems is when I run into data like this:


LINPAVE BUILDING LIMITED	ZBIA	10575.0000	10575.0000	April	2008
LINPAVE BUILDING LIMITED	ZBIA	35250.0000	35250.0000	May	2008

The sp_Crosstab sproc generates the column names properly but it's then supposed to aggregate the 2 values into 1 line.
However, it still presents them as 2 lines as that is how the data is presented:


declare @Value int
set @Value = 10000
SELECT 	cust_name,
	costcent,
	SUM(Invoices.amount) AS amount, 
	SUM(
	CASE 
		WHEN	amount < totamnt AND totamnt = promamt
		THEN	amount
		ELSE  	ISNULL(PromAmt,0)
	END	)AS AmountPromised,
	datename(month, promamtdate) AS MonthName, 
	datename(year, promamtdate) AS YearName
FROM 	Invoices 
WHERE Invoices.PaidFlag = 0 and datename(month, promamtdate) is not null
GROUP BY cust_name, costcent,
	datename(month, promamtdate), 
	datename(year, promamtdate)
HAVING SUM(Invoices.amount) >= @Value
ORDER BY cust_name, costcent

So, I have come up with this


declare @Value int
set @value = 10000

--select datename(month, dateadd(month,-1, getdate()))
SELECT 	cust_name,
	costcent,
	SUM(Invoices.amount) AS amount, 
	SUM(
	CASE 
		WHEN	amount < totamnt AND totamnt = promamt
		THEN	amount
		ELSE  	ISNULL(PromAmt,0)
	END	)AS AmountPromised,
	
	SUM(CASE datename(month, promamtdate) WHEN datename(month, dateadd(month,-2, getdate())) THEN promamt ELSE 0 END) AS [-2],
	SUM(CASE datename(month, promamtdate) WHEN datename(month, dateadd(month,-1, getdate())) THEN promamt ELSE 0 END) AS [-1],
	SUM(CASE datename(month, promamtdate) WHEN datename(month, dateadd(month,0, getdate())) THEN promamt ELSE 0 END) AS [0],
	SUM(CASE datename(month, promamtdate) WHEN datename(month, dateadd(month,+1, getdate())) THEN promamt ELSE 0 END) AS [1],
	SUM(CASE datename(month, promamtdate) WHEN datename(month, dateadd(month,+2, getdate())) THEN promamt ELSE 0 END) AS [2]

FROM 	Invoices 
WHERE Invoices.PaidFlag = 0
GROUP BY cust_name, costcent
HAVING SUM(Invoices.amount) >= @Value
ORDER BY cust_name, costcent

But I need to make the columns dynamic somehow.
Any thoughts? Can I use a varibale in the AS [2] section ?
Or should I do this in the calling application?
