Comma Separated Values in SQL using Stored PRocedure - sql-server-2008

Question

What i currently have is:
COUNT DETAILS:
CNT DTLID COUNT TOTAL QTY UNITPRICE AMOUNT
1 234 2222 1.20 32
1 12 123 2 21
What i want it to be like
CNT DTLID COUNT TOTAL QTY UNITPRICE AMOUNT
1 234,12 2222 , 123 1.20,2 32 + 21 = 53
I want to have comma Separated values and also want to use group by clause for amount column.
Currently What I`m upto is:
ALTER PROCEDURE [dbo].[sp_Tbl_CountDetail_SelectAll]
-- Add the parameters for the stored procedure here
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
select * from Tbl_CountDetail
inner join tbl_Contract
on
tbl_CountDetail.ContractID = tbl_Contract.ContractID
inner join tbl_Count
on
tbl_CountDetail.CountID = tbl_Count.CountID
where tbl_CountDetail.isDeleted = 0
and tbl_Contract.isdeleted = 0
END

Some friendly sample data
create table #CountDetails
(
DTLID int,
CNT int,
Qty int,
UnitPrice money,
Amount int
)
insert into #CountDetails
SELECT
1, 234, 2222, 1.20, 32
UNION ALL SELECT
1, 12, 123, 2, 21
Here's some code
SELECT
DTLIDs.DTLID,
CNTs =
ISNULL(
STUFF(
(
select ',' +
cast(CD.cnt as varchar(50))
from #CountDetails CD
where CD.DTLID = DTLIDs.DTLID
order by CD.CNT
FOR XML PATH('')
),
1, 1, '' --removes the leading ','
),
''
),
QTYs =
ISNULL(
STUFF(
(
select ',' +
cast(CD.qty as varchar(50))
from #CountDetails CD
where CD.DTLID = DTLIDs.DTLID
order by CD.Qty
FOR XML PATH('')
),
1, 1, '' --removes the leading ','
),
''
),
UnitPrices =
ISNULL(
STUFF(
(
select ',' +
cast(CD.UnitPrice as varchar(50))
from #CountDetails CD
where CD.DTLID = DTLIDs.DTLID
order by CD.UnitPrice
FOR XML PATH('')
),
1, 1, '' --removes the leading ','
),
''
),
AmountSum =
(
select SUM(Amount) from #CountDetails CD
where CD.DTLID = DTLIDs.DTLID
)
from (
select distinct DTLID from #CountDetails
) DTLIDs
There are various ways to tweak this. For example, the "AmountSum =" nested query code be done on a group by - I just like the more consistent look given the way the rest of the query is structured.
For the CSV lists, you didn't specify how you wanted it sorted. I've ordered by the values (eg ORDER BY CD.CNT) but you can change that to order by whatever you want. Similarly there are no spaces between the CSV values. You can tweak this by changing the select ',' to have a space in there and parameters to the STUFF command (change the second 1 to a 2).
Basically the FOR XML PATH('') bit takes the mini resultset its given and returns some text with no XML literals (due to the ''). This is tidied up using STUFF to remove the leading , at the start of the XML PATH result.
Hope this helps! :)

Answer 2

Can be done something like this....
DECLARE #VALUES NVARCHAR(1000),#UnitPrice nvarchar(100)
SELECT #VALUES = COALESCE(#VALUES + ',','') + CAST(COUNTQty AS NVARCHAR(50)),
#UnitPrice = COALESCE(#UnitPrice + ',','') + CAST(UnitPrice AS NVARCHAR(50)) FROM tableName
SELECT #VALUES as [CountQty],#Ids as [UnitPrice]
Have not checked group by price issue..!!
