运行这段代码后很长时间最终出现"脚本运行时间过长.."的错误信息，请问是怎么回事啊 ？？我在线等~~~~~~

<!--#include file="conn.asp"-->

<table width="90%" border="1" cellspacing="0" cellpadding="0" height="500">

  <%
set rs=server.CreateObject("adodb.recordset")
rs.open "select big_class_name from big_class order by id desc",conn,1,1
do while not rs.eof
%>
<tr>
<td><%=rs("big_class_name")%></td>
</tr>
<tr>
<%
set rs1=server.CreateObject("adodb.recordset")
rs.open "select * from second_class_name where big_class_name='"&rs("big_class_name")&"' order by id desc"
do while not rs.eof
%>

<%
        rs1.movenext

</tr>
<%
          rs.movenext
    loop
    

    rs.close
    set rs=nothing
  %>

。。。。。。。。。。。。。。？？

set rs1=server.CreateObject("adodb.recordset")
rs.open "select * from second_class_name where big_class_name='"&rs("big_class_name")&"' order by id desc"
do while not rs.eof
改成
set rs1=server.CreateObject("adodb.recordset")
rs1.open "select * from second_class_name where big_class_name='"&rs("big_class_name")&"' order by id desc"
do while not rs1.eof

???
我没看 出来和原来的有什么改动啊？？

rs和rs1

不行啊 ，改过来还是那个问题！

          rs.movenext

</table>

rs1.open "select * from second_class_name where big_class_name='"&rs("big_class_name")&"' order by id desc"
主要是上面那句话的错误
rs1.open "select * from second_class_name where big_class_name='"&rs("big_class_name")&"' order by id desc",conn,1,1

是我太大意了！谢谢了 ！

不推荐这种写法，这种嵌套写法肯定会使脚本时间运行过长。
