ExecuteXmlReade r - How to Use?

[Steve Harclerode]

I'm trying to use an SqlCommand.Exec uteXmlReader() to write data to an XML
file. Most of the code is below. The result I'm seeing is that the schema
file is written and looks good, but the XML file has no data other than an
empty <root> node. Is there something simple I'm missing? BTW, running the
same query in query analyzer returns 7 nodes.

Thanks --
Steve

string cmdString = "SELECT * FROM TestTable order by column1 FOR XML
AUTO, XMLDATA";
DataSet ds = new DataSet();

using ( SqlConnection sc = new SqlConnection( connectionStrin g ) )
{
sc.Open();
SqlCommand cmd = new SqlCommand( cmdString, sc );

XmlReader xr = cmd.ExecuteXmlR eader();
ds.ReadXmlSchem a( xr );
ds.ReadXml( xr, XmlReadMode.Fra gment );
sc.Close();
}

ds.DataSetName = "root";
ds.WriteXml( @"C:\Test.xm l" );
ds.WriteXmlSche ma( @"C:\Test.xs d" );
