Question

I am trying to dynamically write some xml for a webservice. I have recently been shown how to use the FOR XML AUTO clause for my sql query, but I am not sure If one I am writing the query properly and on top of this I am not sure how to return the document values

using (SqlConnection oCn = new SqlConnection())
{
    oCn.ConnectionString = @"server=sql-server\cos;integrated security=SSPI;database=daas5";
    oCn.Open();

    // Create a SQL command object.
    string strSQL = "SELECT * FROM dd615.musicdetails WHERE artistname LIKE '%" + 
                        searchTerm + "%' OR recordname LIKE '%" + searchTerm + "%' 
                        OR recordtype LIKE '%" + searchTerm + "%' 
                        OR format LIKE '%" + searchTerm + "%'
                     FOR XML AUTO, ELEMENTS, ROOT('musicInformation') ";

    SqlCommand myCommand = new SqlCommand(strSQL, oCn);
}          

any help would be greatly appreciated

Answer 1

Your SQL seems fine so far – the best bet would be to use the .ExecuteXmlReader on your SqlCommand object.

XmlReader reader = myCommand.ExecuteXmlReader();

Once you have that, you can easily load this into an XDocument

XDocument doc = XDocument.Load(rdr);

or an XmlDocument

XmlDocument xdoc = new XmlDocument();
xdoc.Load(rdr);

so pick whichever works for you!
