Hi Guys,


I have multiple CTE, I have already merged multiple row into one column.
My concern is how to capture the partno multiple model while it has also the same partno with one model.
I need to group by by partno.. please see my sample result.

Your help is very much appreciated. Thanks.


reate table #Sample
(LFlag int, TranMonth datetime,model nvarchar(35),Itemid nvarchar(35),partno nvarchar(35),
produceqty int,requireqty int,newpartqty int,reclaimqty int,refurbqty int)
insert into #Sample values(3,'2012-09-01','INCREDIBLE','P300-1110-INCREDIBLE-U','HTC1040',6682,61,0.86,0,43)
insert into #Sample values(3,'2012-09-01','INCRDBL2RED','P300-1110-INCRDBL2RED-U','HTC1040',2354,3083,59,0,2)
insert into #Sample values(3,'2012-09-01','INCREDIBLE2','P300-1110-INCREDIBLE2-U','HTC1040',188,188,36,0,0)
insert into #Sample values(2,'2012-08-01','INCREDIBLE','P300-1110-INCREDIBLE-U','HTC1040',6562,68,95,10,15)
insert into #Sample values(2,'2012-08-01','INCRDBL2RED','P300-1110-INCRDBL2RED-U','HTC1040',2354,3083,59,2,25)
insert into #Sample values(1,'2012-07-01','INCREDIBLE2','P300-1110-INCREDIBLE2-U','HTC1040',156,188,36,0,12)
insert into #Sample values(1,'2012-07-01','INCREDIBLE2','P300-1110-INCREDIBLE2-U','HTC1045',186,189,46,3,32)



;With CT

select 
	LFlag,
	TranMonth,
	partNo,
	stuff( ( select distinct ',' + model from #Sample where LFlag = t.LFlag for xml path( '' ) ) , 1, 1, '' ) as model, 
	ISNULL(SUM(Produceqty),0) AS Produceqty,

	SUM(Case When LFlag=2 THen Produceqty Else 0 End) As Produceqty2,
	SUM(Case When LFlag=1 THen Produceqty Else 0 End) As Produceqty3		
From CT
Group by partno, Model--, TranMonth

SELECT 
    CT.partno,
