How? On EoF of a TDataSet? Its clear that you can fetch manually. How do
you do that?

Thats what I would do too. Start a completely new Project makes no
sence, there are good Sources we could take and modify. But for speed
reasons I would support only PostgreSQL and RIP out anything else.

Hm me not really, I fixed up things in zeos but thats all. All in all
that can't be really complicated, there are many small components
(textdrivers) and so that all are TDataSet descendents. So I think thats
not the point most complicated out there.

Hm I think in that way too. But I try to reduce buissines logic in
Delphi. Delphi is still the best RAD - Developement tool IMHO.
