一次显示一行从访问数据库使用ASP经典

Question

我需要帮助与我的asp项目，

有一个循环在我的页面，其中只有一行从表是循环通过整个页面，而不是我想显示只有一行，然后我想添加一个按钮/链接加载第二行，然后第三行，第四行和wards。

我怎样才能做到这一点?

我的代码

<%
if session("usr")="" then
response.Redirect("authentication.asp")
end if
Set Rs=con.execute("select * from Std_Profile where uid=" & session("usr") & "")
Dim ccode
ccode=Rs("Class_Code")
Set RSlecture=con.execute("select * from eva_lecture where Class_Code='"& ccode &"' ")
Set RSques=con.execute("select * from eva_ques ")

Dim PageLen,PageNo,TotalRecord,TotalPage,No,intID
PageLen = 1 
PageNo = Request.QueryString("Page")
if PageNo = "" Then PageNo = 1
TotalRecord = RSlecture.RecordCount
RSlecture.PageSize = PageLen
TotalPage = RSlecture.PageCount
RSlecture.AbsolutePage = PageNo

%>
<div class="activity">
<%
        No=1
        Do While Not RSlecture.EOF and No <= PageLen
%>

你的命令顺序不对。试试这个:

Set RSques=con.execute("select * from eva_ques ")
Dim PageLen, PageNo, TotalRecord, TotalPage, No, intID
PageLen = 1 
PageNo = Request.QueryString("Page")
if PageNo = "" Then PageNo = 1
Set RSlecture = Server.CreateObject("ADODB.Recordset")
RSlecture.CursorLocation = 3 'adUseClient
RSlecture.Open "select * from eva_lecture where Class_Code='"& ccode &"' ", con
RSlecture.PageSize = PageLen
RSlecture.AbsolutePage = PageNo
TotalRecord = RSlecture.RecordCount
TotalPage = RSlecture.PageCount
