I don't see how PHP could do this any better than perl. It is limited
by what Sybase understands, and in this particular case it is limited
by the way SQL works.
As SQL is set-based you can't say "get me rows x through y". Instead
you have to use an appropriately constructed where clause that will
give you the next x rows.
