asp对access不能更新操作但能插入
插入的代码：
<%Sub   Save_Add()

Dim   Info_Title,Id,Merchant_Name,Classid
        Info_Title=Trim(Request( "Title "))
Classid=Clng(Trim(Request( "Classid ")))
IF   info_title= " "   or   Isnull(info_title)   then
Response.Write( " <script> alert( '请输入IT产品! ');window.history.back(); </script> ")
Response.End
END   IF

Set   Rs   =   Server.CreateObject( "Adodb.Recordset ")
      Sql= "Select   Top   1   *   From   Machant_Product   Where   1=0 "  
                Rs.Open   Sql,Conn,1,3
        Rs.AddNew
Rs( "Title ")=Info_Title
Rs( "Parent ")=Classid
Rs( "AddTime ")=Now()
Rs( "UpTime ")=Now()
Rs.Update
Rs.close
End   Sub
%>
要修改记录的进行更新操作
代码：

<%


Select   Case   Request( "Action ")
      Case   "Save_Mod "
　　Call   Save_Mod()
End   Select
Sub   Save_Mod()
Dim   Info_Title,Classid,brandid,Sql,Rs
BrandID   =   Trim(Request( "id "))
IF   BrandID   =   " "   or   Isnull(BrandID)then
Response.Write( " <script> alert( '参数错误！ ');window.history.back(); </script> ")
Response.End
END   IF
        　　Info_Title=Trim(Request( "Title "))
Classid=Clng(Trim(Request( "Classid ")))
Set   Rs   =   Server.CreateObject( "Adodb.Recordset ")
      Sql= "Select   Top   1   *   From   Machant_Product   Where   Id= "&CLng(BrandID)
                Rs.Open   Sql,Conn,１,3
If   Not(Rs.Bof   And   Rs.Eof)   Then
Rs( "Title ")=Info_Title
Rs( "Parent ")=Classid
Rs( "AddTime ")=Now()
Rs( "UpTime ")=Now()
Rs.Update
end   if
Rs.close:Set   Rs=Nothing
  Response.Redirect "Brand_Manage.asp "
End   Sub
%>

BrandID   =   Trim(Request( "id "))是这样   <input   name= "Id "   type= "hidden "   value= " <%=Rs( "id ")%> "> 传递的
到底是哪里出了差错呢？


------解决方案--------------------
Save_Mod '这样调用看看
Sub Save_Mod()
Response.Redirect "Brand_Manage.asp "
End Sub

直接运行上面的看看会不会成功
