大鹰,关于你在精华区的树状结构存储过程的贴子的内容好像不对呀,我做了实验,只能取根帖,我改了一下,在query analyzer中可以,但在页面上只能显示出一部分,你帮忙看一下好吗             
CREATE proc up_TopicList
            @a_ForumID int ,  @a_intPageNo int , @a_intPageSize tinyint
   as
       declare @m_intRecordNumber int
       declare @m_intStartRecord  int
     declare @m_intRootID  int
       select @m_intRecordNumber = @a_intPageSize * @a_intPageNo
       select @m_intStartRecord = @a_intPageSize * (@a_intPageNo - 1) + 1

    
                /*求符合条件记录数*/
                select "RecordCount" = count(*)                         
                       from BBS where Layer=1 and ForumID = @a_ForumID

               /*输出纪录*/
               /*首先定义可滚动光标*/
               set rowcount @m_intRecordNumber
               declare m_curTemp Scroll cursor
                       for
                          select ''rootID''=a.rootID                                     
                                from BBS as a
                                     join BBSUser as d on a.UserID = d.[ID]
                                where a.Layer=1 and a.ForumID = @a_ForumID
                                order by RootID desc , Layer , PostTime desc
               open m_curTemp
               fetch absolute @m_intStartRecord from m_curTemp into @m_intRootID
               
     while  (@@fetch_status = 0)
        begin
            select ''ID'' = a.[ID] ,
            ''Title'' = a.Title ,
            ''UserName'' = d.UserName ,
            ''Hits'' = a.Hits,
            ''Face'' = a.Face ,
            ''Layer''=a.Layer,
                                    ''ContentSize'' = datalength(a.Content) ,
                                    ''TotalChilds'' = (select sum(TotalChilds)
                                                        from BBS as b
                                                        where a.RootID = b.RootID) ,
                                ''LastReplyTime'' = a.PostTime
                                     
                                from BBS as a
                                     join BBSUser as d on a.UserID = d.[ID]
                                where a.Layer>=1 and a.ForumID = @a_ForumID and a.rootID=@m_intRootID
                                order by RootID desc , Layer , PostTime desc
        fetch next from m_curTemp into @m_intRootID
        end
               set rowcount 0
               /*清场*/       
               CLOSE m_curTemp
               DEALLOCATE m_curTemp
GO
