SQL Summing and Grouping

How can I modify this query to display what it already does but also include the total SUM either in a separate row or column of InvPayAmnt per each select which has a unique CardName?

SELECT IdEntry, 
       DocNum, 
       'MICHIGAN' + CardCode, 
       QUOTENAME(CardName,'"'), 
       Convert(Decimal(10,2),InvPayAmnt), 
       CONVERT(VARCHAR(10), T5.PmntDate,101), 
       NumAtCard, 
       PymMeth, 
       'Objtype' = CASE WHEN Objtype = 19 THEN 'CREDIT' ELSE 'INVOICE' END
FROM MICHIGAN.dbo.PWZ3
INNER JOIN MICHIGAN.dbo.OPWZ T5 ON T5.IdNumber = IdEntry
WHERE T5.PmntDate = '4/1/2011' 
AND T5.Canceled = 'N' 
AND Checked = 'Y'
UNION
SELECT IdEntry, 
       DocNum, 
 开发者_JAVA技巧      'BEN' + CardCode, 
       QUOTENAME(CardName,'"'), 
       Convert(Decimal(10,2),InvPayAmnt), 
       CONVERT(VARCHAR(10),T5.PmntDate,101), 
       NumAtCard, 
       PymMeth, 
       'Objtype' = CASE WHEN Objtype = 19 THEN 'CREDIT' ELSE 'INVOICE' END
FROM BENSALEM.dbo.PWZ3
INNER JOIN BENSALEM.dbo.OPWZ T5 ON T5.IdNumber = IdEntry
WHERE T5.PmntDate = '4/1/2011' 
AND T5.Canceled = 'N' 
AND Checked = 'Y'
ORDER By 3

It would also work if the sum was placed in the last column, either way would be fine.

Because of the convert() call I assume you are using SQL Server.

If you have a fairly recent version (2005 or later), the following should work:

SELECT ....
       sum(InvPayAmnt) over (partition by CardName) as payment_sum
FROM ....
