Question

I’m creating a DotNetNuke module that needs to read entries from a SQL Server table called SalesOrders. The module must only display those records where STatus = Pending. I need to create an XML file from my database table that selects records per above. How is this done in Visual Studio 2010? I started to use the XML Schema Explorer to create the XSD by hand. Not sure if this is correct approach? Note that I’ll need to do XSL transformation so that I can make the contents of the XML file available to my module, so that I can permit the user to select Invoices within a given date range. In the module, the user needs to enable a checkbox for each invoice read from the XML file and mark them as paid.

Am I taking the proper approach relative to creating the XSD by hand, or is there a more automated approach?

Thanks much!!

This Code will fill a datatable then write it to an xml string:

    DataTable dt = new DataTable();
    using (System.Data.SqlClient.SqlConnection connection = new System.Data.SqlClient.SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["connection"].ConnectionString))
    {
        connection.Open();

        System.Data.SqlClient.SqlCommand command = new System.Data.SqlClient.SqlCommand();
        command.Connection = connection;

        command.CommandText = @"SELECT * FROM  SalesOrders WHERE STatus = 'Pending'";

        System.Data.SqlClient.SqlDataAdapter adapter = new System.Data.SqlClient.SqlDataAdapter(command);
        adapter.Fill(dt);
    }
    MemoryStream ms = new MemoryStream();
    dt.WriteXml(ms, XmlWriteMode.IgnoreSchema);
    ms.Seek(0, SeekOrigin.Begin);
    StreamReader sr = new StreamReader(ms);
    string xml = sr.ReadToEnd();
    ms.Close();
    return xml;

you can use different methods to fill the datatable if you want
