Now that our GetEmployees endpoint is ready, we can create a proxy for it. The procedure for this is the same as the one in 9. You need to create a Windows application by using Visual Studio and then add a web reference to it. You might be wondering what URL you have to supply in the Add Web Reference dialog box. Assuming that SQL Server is running on your local machine, the URL will be http://localhost/sql/GetEmployees wsdl. Remember that we specified /sql/GetEmployees as the PATH while creating the endpoint. At the end of the URL, you need to append the wsdl query string parameter. This way, SQL Server will return the WSDL document for your web service. Figure 10-10 shows the Add Web Reference dialog box with the URL entered.

Figure 10-11. Application that consumes the native web service The form consists of a DataGridView control. The records returned by the native web service are displayed in it. The code that calls the GetEmployees web method and binds the DataGridView with the results is shown in Listing 10-39. Listing 10-39. Calling Web Methods using WSClient.localhost; using System.Net; private void Form1_Load(object sender, EventArgs e) { GetEmployeesEndPoint proxy = new GetEmployeesEndPoint(); proxy.Credentials = CredentialCache.DefaultCredentials; object[] results=proxy.GetEmployees(); dataGridView1.DataSource = ((DataSet)results[0]).Tables[0].DefaultView; } The code imports the namespace for the proxy class. In the Load event of the form, an object representing the proxy is created. Note that we have called our endpoint GetEmployeesEndPoint, so the same name is given to the proxy class. Then the Credentials property of the proxy class is set to the DefaultCredentials property of the CredentialCache class, which resides in the System.Net namespace and allows you to pass user credentials to the proxy. Recollect that while creating the endpoint, we specified the AUTHENTICATION mode as INTEGRATED. The DefaultCredentials property returns the Windows credentials of the current user. Then the code calls the GetEmployees() method on the proxy. The return value of GetEmployees() is an object array, which contains two elements. The first element contains the actual return value as returned by the web method, and the second parameter is of type SqlRowCount. The SqlRowCount class contains a property called Count that tells you the number of rows returned by the web method. The records returned by the SELECT query are received as a DataSet object in .NET applications. Hence the code type casts the first element of the array to DataSet. Finally, the DataSet is bound to the DataGridView.

Summary
SQL Server provides strong integration with XML. This chapter introduced you to many of the XML features of SQL Server, which allows you to view relational data as XML. This is done with the help of the FOR XML clause of the SELECT statement. You can also look at XML data in a relational way by using the OPENXML function. We also saw how SQL Server makes it easy to retrieve data in a client application over HTTP with the help of the SQLXML managed classes. These classes allow you to select data as a stream, an XmlReader, or a DataSet. They also allow you to update UpdateGrams and DiffGrams in the database. The XML data type of SQL Server can be used to store whole XML documents or fragments and allows you to manipulate them via XML DML. You can expose stored procedures and functions as web methods by creating native web services. These native web services can be consumed by client applications in a way similar to their consuming .NET web services.
