You cannot do any of these things in any relational database. You can only do
this in navigational databases. There are various kludges which permit you to
simulate navigational abilities on top of relational databases, but they are
all kludges which are performed by various forms of fakery
I'm racking my brain trying to figure out how to get directly to the last item
in a (potentially)
sorted or ordered table. At least oe of the tables will be ordered by a name
and a date,
so uising the rtowid won't work.
Also, how to traverse a table or cursor in a reverse direction.
