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" /> <Order CustomerID="TORTU" OrderID="10576" OrderDate="1997-06-23T00:00:00" /> <Order CustomerID="TORTU" OrderID="10676" OrderDate="1997-09-22T00:00:00" /> <Order CustomerID="TORTU" OrderID="10842" OrderDate="1998-01-20T00:00:00" /> <Order CustomerID="TORTU" OrderID="10915" OrderDate="1998-02-27T00:00:00" /> <Order CustomerID="TORTU" OrderID="11069" OrderDate="1998-05-04T00:00:00" /> </Customer> </XML> Orders.xml <?xml version="1.0" ?> <Schema xmlns="urn:schemas-microsoft-com:xml-data" xmlns:dt="urn:schemas-microsoft-com:datatypes" xmlns:sql="urn:schemas-microsoft-com:xml-sql"> <ElementType name="Order" sql:relation="Orders"> <AttributeType name="CustomerID" /> <AttributeType name="OrderID" /> <AttributeType name="OrderDate" /> <attribute type="CustomerID" sql:field="CustomerID" /> <attribute type="OrderID" sql:field="OrderID" /> <attribute type="OrderDate" sql:field="OrderDate" /> </ElementType> <ElementType name="Customer" sql:relation="Customers"> <AttributeType name="CustomerID" /> <AttributeType name="CompanyName" /> <attribute type="CustomerID" sql:field="CustomerID" /> <attribute type="CompanyName" sql:field="CompanyName" /> <element type="Order"> <sql:relationship key-relation="Customers" key="CustomerID" foreign-key="CustomerID" foreign- relation="Orders" /> </element> </ElementType> </Schema> 返回类别: 教程 上一教程: 正则表达式在网络编程中的运用(2) 下一教程: 使用ASP重启服务器 您可以阅读与"在SQL2000查询中使用XDR的例子"相关的教程: · 通过几个异常实用的例子了解ASP中使用正则表达式 · 在ASP中使用SQL语句之2:用WHERE子句设置查询条件 · 实现分页的例子-使用存储过程来实现分页 · 在ASP中使用SQL语句之6:存储查询 · ASP直接调用EXCEL数据的例子 |
