Vous n'avez pas de fonction équivalente pour cela, mais vous pouvez toujours simuler (utilisez CROSS APPLY
et FOR XML PATH('')
). exemple,
USERID ADDRESSLINE1
==========================
1 First Street
1 Second Street
2 32th Street
2 24th Street
2 25th Street
résultera
USERID ADDRESSLIST
============================
1 First Street, Second Street
2 32th Street, 24th Street, 25th Street
Utilisation de cette requête :
SELECT a.UserID,
SUBSTRING(d.Addresses,1, LEN(d.Addresses) - 1) AddressList
FROM
(
SELECT DISTINCT UserID
FROM tableName
) a
CROSS APPLY
(
SELECT [AddressLine1] + ', '
FROM tableName AS B
WHERE A.UserID = B.UserID
FOR XML PATH('')
) D (Addresses)
