请问此段程序有问题吗？为什么运行的时候总是好久不显示结果？
这是通过一个表里的数据查询另外一个表里是否也有，如果有并显示出来
但运行好长时间都不显示结果，

<table>
  <tr> <td> 条码 </td> </tr>
<%
sql= "select   *   from   webhz "
set   rs=server.createobject( "adodb.recordset ")
rs.open   sql,conn
do   while   rs.eof <> true
tiaoma=rs( "tiaoma ")
  set   rs1=server.createobject( "adodb.recordset ")
  rs1.open   "select   *   from   oraclee   where   tiaoma= ' "&tiaoma& " ' ",conn
  if   rs1.eof <> true   then%>
  <tr> <td> <%=rs1( "tiaoma ")%> </td> </tr>
<%
end   if
rs1.close
rs.movenext
loop
rs.close
%>
</table>

------解决方案--------------------
rs1.close
set rs1=nothing

rs.close
set rs=nothing

注意释放

可能是数据库数据量太大.
------解决方案--------------------
每循环一次都set 一次rs1而且不释放，优化一下吧，
sql= "select O.tiaoma from webhz W left outer join oraclee O on W.tiaoma=O.tiaoma "
rs.open sql,conn,1,1
do while not rs.eof
if not isnull(rs( "tiaoma ")) then
response.write rs( "tiaoma ")
end if
rs.movenext
loop
rs.close
