Invoke a Function in Oracle Database using the WCF Channel Model

This section demonstrates how to execute a function in an Oracle database using the channel created in Create a Channel using Oracle Database.

Executing a Function Using the Channel

You can execute a function on an Oracle database by passing an XML message to Microsoft BizTalk Adapter for Oracle Database. The input XML resembles the following:

<CREATE_ACCOUNT xmlns="http://Microsoft.LobServices.OracleDB/2007/03/SCOTT/Package/ACCOUNT_PKG" xmlns:ns0="http://Microsoft.LobServices.OracleDB/2007/03/SCOTT/Package/ACCOUNT_PKG/CREATE_ACCOUNT">  
  <REC xmlns="http://Microsoft.LobServices.OracleDB/2007/03/SCOTT/Package/ACCOUNT_PKG">  
    <ns0:ID>1</ns0:ID>  
    <ns0:NAME>Scott</ns0:NAME>  
    <ns0:BANKNAME>CitiBank</ns0:BANKNAME>  
    <ns0:BRANCH>NY</ns0:BRANCH>  
    <ns0:ENABLED>Y</ns0:ENABLED>  
  </REC>  
</CREATE_ACCOUNT>  

The following code excerpt demonstrates how to execute a function in an Oracle database using a channel.

            EndpointAddress address = new EndpointAddress("oracledb:// ADAPTER");  
  
            // Create Binding  
            OracleDBBinding binding = new OracleDBBinding();  
  
            // Create Channel Factory  
            ChannelFactory<IRequestChannel> factory = new ChannelFactory<IRequestChannel>(binding, address);  
            factory.Credentials.UserName.UserName = "SCOTT";  
            factory.Credentials.UserName.Password = "TIGER";  
            factory.Open();  
  
            // Create Request Channel  
            IRequestChannel channel = factory.CreateChannel();  
            channel.Open();  
  
            // Send Request  
            System.Xml.XmlReader readerIn = System.Xml.XmlReader.Create("Create_Account.xml");  
  
            Message messageIn = Message.CreateMessage(MessageVersion.Default, "http://Microsoft.LobServices.OracleDB/2007/03/SCOTT/Package/ACCOUNT_PKG/CREATE_ACCOUNT", readerIn);  
            Message messageOut = channel.Request(messageIn);  
  
            // Get Response XML  
            XmlReader readerOut = messageOut.GetReaderAtBodyContents();  
  
            // Get Employee ID  
            XmlDocument doc = new XmlDocument();  
            doc.Load(readerOut);  
            doc.Save("d:\\out.xml");  
  
            messageOut.Close();  
            channel.Close();  
        }  
    }  
}
