Perhaps something to do with the structure of the dataset then. Isn't the datareader kind of open in that regard - i.e. it will eat whatever it is fed. I know there were some remote view issues in VFP/VFE if we defined remote views with select * and then the structure changed on the backend. ( though that may have had to do with the dbgetprops etc )
