Efran,

Sorry I overlooked your comment the other day.  I understand your comments
about the IDataReader - they do make sense.  Still, it seemed that there
might be a 'normal' method to achieve what I wanted.  I also understand that
if the underlying code/app design was clearly thought out and 'finalized',
then the 'want' I was looking for wouldn't be needed! :-)

Thanks for the comments.

Peter

Hi Peter,

To me it makes perfect sense the *DataReader does not hold a resultset index
state. By design, IDataReader is a forward only reader; it tends to not hold
any state while running, in order to achieve the best possible performance.
Btw it doesn't hold the active row index neither.

HTH,
