C#.NET - LoadDataSet Does Not Generate XML Data

I have been searching the web but cannot seem to find an answer to
this question. I'm hoping that someone here can help me with this...
Thanks in advance...

I have the following snippet of code:

---------------------------------------------------------------------------------------
strCompany = "select * from Company ";
db2.LoadDataSet(db.GetSqlStringCommand(strCompany), ds, "Company");
---------------------------------------------------------------------------------------

The code will create a dataSet for me based on the information in the
Company table...no problem. The problem comes from the fact that one
of the columns in the Company table has no data in it...all of the
data in this particular column is NULL.

So, when the dataSet is created, this column (i.e.: Address) is
missing from the dataSet. When I try to generate an Xml document from
this dataSet, there is no <Address> element in the Xml.

Is there a way to make this .LoadDataSet (or some other method)
generate data so that there will be an <Address> element when I go to
create the Xml file?

What is the best way to do this?

Thanks So Much...
