MS SQL Server 2008架构设置：

CREATE TABLE tblUsers
    ([name] varchar(7))
;

INSERT INTO tblUsers
    ([name])
VALUES
    ('asieh'),
    ('amir'),
    ('safoora')
;

查询1 ：

    SELECT STUFF((
        select ','+ name 
        from tblUsers
        FOR XML PATH('')
        )
        ,1,1,'') AS names

<强> Results ：

|              NAMES |
|--------------------|
| asieh,amir,safoora |

Answer 2

这是使用变量的解决方案：

DECLARE @out VARCHAR(MAX)
SELECT @out = COALESCE(@out+',' ,'') + name
FROM tblUsers
SELECT @lout

Answer 3

试试这个：

Create Table #tblUsers ( Name Varchar(100) );
Insert Into #tblUsers Values ('Row1; asieh'),('Row2:amir'),('Row3:safoora')

Select Stuff((Select ',' + Name
                From #tblUsers
                 For Xml Path('')
       ), 1, 1, '' ) As ConcatenedString

drop table #tblUsers

SQL Server选择结果为字符串，以'，'分隔
