Well... there are two reason why row buffering don't work in dblib:
1- column_cur_size information it's not stored in row, so you loose this
information
2- text are not handled correctly (causing leaks)

I think it's better to change row handling before fixing row
buffering... noone complained about row buffering and we are more free
to change code.

If we don't need to store row cause we want to use (I still don't know
how) direct binding it's normal that row buffering should be removed.
Could you describe me briefly the main differences between dblib BCP and
ctlib BCP. From what I see dblib it's bound to file while ctlib it's
bound to client variables... I think to port ctlib way to libTDS and use
libTDS to code dblib BCP. Do you think this it's the better way?? Do you
have any pending patch for BCP? You are the BCP man :)...
