在SQL2000查询中使用XDR的例子

XDR不会不知道吧？就是简化的XML-Data啦。现在示范一个如何实现这样的查询
SELECT o.OrderID, o.OrderDate from Orders o, Customers c,
WHERE o.CustomerID = c.CustomerID and c.CompanyName = ?
Code:
<%@ Language=VBScript %>
<%
Dim sConn
sConn = "Provider=SQLOLEDB; Data Source=(local); Initial Catalog=Northwind; User ID=SA;Password=;"

Dim adoConn
Set adoConn = Server.CreateObject("ADODB.Connection")
adoConn.ConnectionString = sConn
adoConn.CursorLocation = 3 'adUseClient
adoConn.Open

Dim adoCmd
Set adoCmd = CreateObject("ADODB.Command")
Set adoCmd.ActiveConnection = adoConn
adoCmd.CommandText = "Customer[@CompanyName=""Tortuga Restaurante""]"
adoCmd.Dialect = "{ec2a4293-e898-11d2-b1b7-00c04f680c56}"

adoCmd.Properties("Mapping Schema") = "Orders.xml"
adoCmd.Properties("Base Path") = "C:INETPUBWWWROOTPBA"
adoCmd.Properties("Output Stream") = Response

Response.write "<XML ID='MyDataIsle'>"
adoCmd.Execute , , 1024 'adExecuteStream
Response.write "</XML>"
%>
Result:
<XML ID="MyDataIsle">
<Customer CustomerID="TORTU" CompanyName="Tortuga Restaurante">
<Order CustomerID="TORTU" OrderID="10276" OrderDate="1996-08-08T00:00:00" />
<Order CustomerID="TORTU" OrderID="10293" OrderDate="1996-08-29T00:00:00" />
<Order CustomerID="TORTU" OrderID="10304" OrderDate="1996-09-12T00:00:00" />
<Order CustomerID="TORTU" OrderID="10319" OrderDate="1996-10-02T00:00:00" />
<Order CustomerID="TORTU" OrderID="10518" OrderDate="1997-04-25T00:00:00" />
