自己写的部分实用的代码

news.asp
<%
 set rs server.createobject("adodb.recordset")
sql="select * from neixun order by id desc"
rs.open sql ,conn,1,3
%>
新闻：
<% do while not rs.eof %>
<a href =neixun.asp?id=<% = rs("id") %>><% = trim(rs("title")) %>
<%
rs.movenext
loop
%>
neixun.asp
<%
id=request.querystring("id")
set rs=server.createobject("adodb.recordset")
sql="select * from neixun where id="&id
rs.open sql,conn,1,3
%>
新闻标题：<% = rs("title") %>
新闻内容：<% = rs("news" ) %>
