これに相当する機能はありませんが、シミュレートすることはできます(CROSS APPLY
を利用してください)。 およびFOR XML PATH('')
)。例、
USERID ADDRESSLINE1
==========================
1 First Street
1 Second Street
2 32th Street
2 24th Street
2 25th Street
結果になります
USERID ADDRESSLIST
============================
1 First Street, Second Street
2 32th Street, 24th Street, 25th Street
このクエリの使用:
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)
