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

结果:

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

这是使用变量的解决方案:

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