在SQL2000查询中使用XDR的例子

类别: 数据库教程  评论数:0 总得分:0
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" />
