Csaba,
I guess the angle is: I, as a practicing DBA would like to be able to
experiment and get most out of the imperfect tool I have, and you, the
developers, want to make the tool perfect... I don't care about perfect
tools, it just have to do the job... hints or anything else, if I can
make it work GOOD ENOUGH, it's all fine. And hints is something I would
understand and be able to use.
Hmmm, if you already understand Visual Basic syntax, should we support
that too? Or maybe we should support MySQL's use of '0000-00-00' as the
"zero" date because people "understand" that?
We're just not going to adopt a bad design because Oracle DBAs are used
to it. If we wanted to do that, we could shut down the project and
join a proprietary DB staff.
The current discussion is:
a) Planner tweaking is sometimes necessary;
b) Oracle HINTS are a bad design for planner tweaking;
c) Can we come up with a good design for planner tweaking?
So, how about suggestions for a good design?
