SQL Server中尚未通过XML data（）命令显示的一个方法是：

假设一个名为NameList的表有一列名为FName，

SELECT FName + ', ' AS 'data()'
FROM NameList
FOR XML PATH('')

返回：

"Peter, Paul, Mary, "

只需处理额外的逗号。

正如@NReilingh的注释所采用的，您可以使用以下方法删除尾随逗号。假设表和列名相同：

STUFF(REPLACE((SELECT '#!' + LTRIM(RTRIM(FName)) AS 'data()' FROM NameList
FOR XML PATH('')),' #!',', '), 1, 2, '') as Brands

在Chris Shaffer的回答之上：

如果您的数据可能会重复，例如

Tom
Ali
John
Ali
Tom
Mike

而不是汤姆、阿里、约翰、阿里、汤姆、迈克

您可以使用DISTINCT避免重复，并让Tom、Ali、John、Mike：

DECLARE @Names VARCHAR(8000)
SELECT DISTINCT @Names = COALESCE(@Names + ',', '') + Name
FROM People
WHERE Name IS NOT NULL
SELECT @Names

在SQLServer2005及更高版本中，使用下面的查询连接行。

DECLARE @t table
(
    Id int,
    Name varchar(10)
)
INSERT INTO @t
SELECT 1,'a' UNION ALL
SELECT 1,'b' UNION ALL
SELECT 2,'c' UNION ALL
SELECT 2,'d' 

SELECT ID,
stuff(
(
    SELECT ','+ [Name] FROM @t WHERE Id = t.Id FOR XML PATH('')
),1,1,'') 
FROM (SELECT DISTINCT ID FROM @t ) t

我真的很喜欢Dana回答的优雅，只想让它变得完整。

DECLARE @names VARCHAR(MAX)
SET @names = ''

SELECT @names = @names + ', ' + Name FROM Names

-- Deleting last two symbols (', ')
SET @sSql = LEFT(@sSql, LEN(@sSql) - 1)
