帮小弟看看啊，以下是我测试的代码：
<!--#include file="conn/conn.asp" -->
<form name="form2" action="hire_save.asp" method="post">

  <select size=1 id="dept" style="WIDTH: 120px">
                  <option value="部门不限" selected>部门不限</option>
                  <%
                             sqlz="select dept_id,dept_name from Comjobtype where dept_cmember='"&cmember_login&"'"
                             response.Write sqlz
                             rsz.open sql,conn,1,1
                             if not(rsz.eof and rsz.bof) then
                                     
                            
                             do while not rsz.eof
                                response.write"<OPTION value="&rsz("dept_name")&">"&rsz("dept_name")&"</option>"
                              rsz.movenext
                             loop
                             end if
                             rsz.close
                            %>
  </select>
                <p></p>
<select name="s1">
  <option value="请选择" selected>岗位类别大类</option>
   <%
set rs = Server.CreateObject("ADODB.Recordset")
sql="select * from classification order by position_id desc"
rs.open sql,conn,1,1
while not rs.eof%>
        <option value="<%=rs("position_id")%>"><%=rs("position_name")%></option>
  <%rs.movenext
  wend
rs.close
set rs=nothing
%>
</select>

<select name="s2">
<option value="请选择" selected>岗位类别小类</option>
</select>

<select name="s11">
  <option value="请选择" selected>航线区域大类</option>
   <%
set rs = Server.CreateObject("ADODB.Recordset")
sql="select * from sail order by fid desc"
rs.open sql,conn,1,1
while not rs.eof%>
        <option value="<%=rs("fid")%>"><%=rs("sail")%></option>
  <%rs.movenext
  wend
rs.close
set rs=nothing
%>
</select>

<select name="s21">
<option value="请选择" selected>航线区域小类</option>
</select>

<input type="button">
</form>

rsz.open sql,conn,1,1
rsz在哪定义的,在conn里？延时个人认为是死循环或是sql语句的问题
