Hier ist A Vorgehensweise (funktioniert auch mit 2005):
Tabelle
DECLARE @table TABLE
(
[Type_ID] INT,
[Client_ID] VARCHAR(50),
[PBX_Vendor] VARCHAR(50)
)
Daten
INSERT INTO @table
SELECT 127,
'090820006311404926326C',
'Aastra'
UNION ALL
SELECT 127,
'090820006311404926326C',
'Ericsson'
UNION ALL
SELECT 127,
'111012237401404926326C',
'Aastra'
UNION ALL
SELECT 127,
'120209287521404926326C',
'Aastra'
UNION ALL
SELECT 127,
'120209287521404926326C',
'Alcatel'
Abfrage
SELECT [Type_ID],
[Client_ID],
(
SELECT STUFF((
SELECT ',' + [PBX_Vendor]
FROM @table
WHERE [Client_ID] = tbl.[Client_ID]
AND [Type_ID] = tbl.[Type_ID]
GROUP BY [PBX_Vendor]
ORDER BY [PBX_Vendor]
FOR
XML PATH('')
), 1, 1, '')
) PBX_Vendor
FROM @table tbl
GROUP BY [Type_ID],
[Client_ID]
Ergebnis
