Sql Server 列转逗号隔开的字符串 和 逆转

SELECT  STUFF(( SELECT  ‘,‘ + ModifyBy
                FROM    dbo.tbl_stationprofile
              FOR
                XML PATH(‘‘)
              ), 1, 1, ‘‘) AS Name    

逗号隔开的字符串转表

RETURNS @TempTable TABLE ([ID] VARCHAR(50))

    IF @InStr IS NULL OR rtrim(ltrim(@InStr))=‘‘
        RETURN

自己创建表函数自己试吧。下面就不上图了。
