Does the number stay the same for the entire dataset? If so, you could
always setup an outputParameter for the oda dataset and set the value there.

Output parameters do show up in the data set editor, but that does not
mean that they can be set. When they show up users can reference them
in a bound table by calling outputParams["myoutputparameter"]. If you
want to implement one you need to implement the getParameterMetaData()
method in the class that implements the IQuery. Also return true in
your class that implements IDataSetMetaData for the the
supportsOutParameters method.

BTW if you think this will be to difficult for your users to find, I
would just add it as a column.
