我们可以用SQL使记录按顺序显示：
我们想显示"Companyname" 和 "Contactname" 字段的内容，并且按"Companyname"进行排序显示：
<html>
<body>
<%
set conn=Server.CreateObject("ADODB.Connection")
conn.Provider="Microsoft.Jet.OLEDB.4.0"
conn.Open "e:/webjx/webjx.mdb"
set rs = Server.CreateObject("ADODB.recordset")
sql="SELECT Companyname, Contactname FROM Customers ORDER BY CompanyName"
rs.Open sql, conn
%>
<table border="1" width="100%">
<tr>
<%for each x in rs.Fields
response.write("<th>" & x.name & "</th>")
next%>
</tr>
<%do until rs.EOF%>
<tr>
<%for each x in rs.Fields%>
<td><%Response.Write(x.value)%></td>
<%next
rs.MoveNext%>
</tr>
<%loop
rs.close
conn.close%>
</table>
</body>
</html>

conn.Provider="Microsoft.Jet.OLEDB.4.0"
conn.Open(Server.Mappath("e:/webjx/webjx.mdb"))
set rs = Server.CreateObject("ADODB.recordset")
sql="SELECT Companyname, Contactname FROM Customers ORDER BY CompanyName DESC"
rs.Open sql, conn
%>
<table border="1" width="100%">
<tr>
<%for each x in rs.Fields
response.write("<th>" & x.name & "</th>")
next%>
</tr>
<%do until rs.EOF%>
<tr>
<%for each x in rs.Fields%>
<td><%Response.Write(x.value)%> </td>
<%next
rs.MoveNext%>
</tr>
<%loop
rs.close
conn.close
%>
</table>
</body>
</html>
按用户的需求自己选择排序方式，比如按公司名称或联系人排序：（把下面文件保存为demo_sort.asp ）
<html>
<body>
<table border="1" width="100%" bgcolor="#fff5ee">
<tr>
<th align="left" bgcolor="#b0c4de">
<a href="demo_sort.asp?sort=companyname">公司名</a>
</th>
<th align="left" bgcolor="#b0c4de">
<a href="demo_sort.asp?sort=contactname">联系人</a>
</th>
</tr>
<%
if request.querystring("sort")<>"" then
sort=request.querystring("sort")
else
sort="companyname"
end if
set conn=Server.CreateObject("ADODB.Connection")
conn.Provider="Microsoft.Jet.OLEDB.4.0"
conn.Open(Server.Mappath("e:/webjx/webjx.mdb"))
set rs=Server.CreateObject("ADODB.recordset")
sql="SELECT Companyname,Contactname FROM Customers ORDER BY " & sort
rs.Open sql,conn
do until rs.EOF
response.write("<tr>")
for each x in rs.Fields
response.write("<td>" & x.value & "</td>")
next
rs.MoveNext
response.write("</tr>")
loop
rs.close
conn.close
%>
</table>
</body>
</html>
