把一列拼接成字符串解决方法_ASP.NET

把一列拼接成字符串
select id from A
结果为
1
2
3
4
我现在想结果为1,2,3,4

在sqlserver2005中，这个该怎么写呢？请教，谢谢啦！

DECLARE @T TABLE(  tid INT)INSERT INTO @TSELECT 1 UNION ALLSELECT 2 UNION ALLSELECT 3 UNION ALLSELECT 4 DECLARE @sql VARCHAR(50) SET @sql=''SELECT @sql=@sql+','+CAST(tid AS VARCHAR(4)) FROM @TPRINT right(@sql,LEN(@sql)-1)/*（所影响的行数为 4 行）1,2,3,4*/
