ASP：do while loop 循环问题

<%
set rs3=server.createobject("adodb.recordset")
sql3="select * from proclass where parentcla=1452"
rs3.open sql3,conn,1,1
if not isempty(request("page")) then
pagecount=cint(request("page"))
else
pagecount=1
end if
rs3.pagesize=4
rs3.AbsolutePage=pagecount
rec=rs3.PageCount
%><%
i=1
do while not rs3.eof
classcode3=rs3("classcode")
%>

<%=rs3("classname")%>

<%
rs3.movenext
loop
rs3.close
%>


<%
set rs4=server.createobject("adodb.recordset")
sql4="select * from products where ClassID="&classcode3&" by

id desc"
response.Write sql4
rs4.open sql4,conn,1,1
do while not rs4.eof
%>
这是是循环内穷容.....
<%rs4.movenext
loop
rs4.close
%>
