FROM
(
SELECT 1111 AS [C no.], 'ken' AS [Name], 'shiro' AS Item, '3/3/2000 12:22' AS [Date], '$25' AS Amount
UNION ALL
SELECT 1111 AS [C no.], 'ken' AS Name, 'aeshte' AS Item, '3/3/2000 12:22' AS [Date], '$25' AS Amount
UNION ALL
SELECT 1111 AS [C no.], 'ken' AS Name, 'taro' AS Item, '3/3/2000 12:22' AS [Date], '$25' AS Amount
UNION ALL
SELECT 2222,'yakumo','tesen','3/4/2000 12:22','$22'
UNION ALL
SELECT 2222,'yakumo','aoie','3/4/2000 12:22','$22'
UNION ALL
SELECT 3333,'kage','manase','3/5/2000 12:22','$21'
) A

SELECT
[C No.],
Name,
[Date],
Amount,
STUFF((
SELECT ',' + A.Item
FROM taro A
WHERE A.[C no.] = B.[C no.]
AND A.Name = B.Name
AND A.[Date] = B.[Date]
AND A.[Amount] = B.[Amount]
ORDER BY item
FOR XML PATH(''),TYPE).value('(./text())[1]','VARCHAR(MAX)'),1,1,'') AS ItemValue
FROM taro B
GROUP BY [C No.],Name,[Date],Amount
