 That's the problem in this job. Too many men. And among women, too many
are like honorary men.


Still preaching the gospel, as you can see :-). In fact, I would be
curious to compare the join on the inline-view with a MINUS to the hash
anti-join. Assuming all correct indexes, it is comparing two index fast
full scans plus sort plus index search to two table full scans (more or
less). I am almost certain that many costs could be put into equations.
The problem is if you have too many values (number of rows, number of
rows returned, storage, selectivity, etc...) to feed into your equations
or have trouble deriving these it is not of much use.
Wanted to do some tests on reverse indexes, following your posts, but I
have not had time. Not much progress on the book PL/SQL chapter either.
Currently working on real-time, home-made replication (which works on
the standard edition, BTW). Still revolving around the same topics
because one of my concerns is to minimize overhead when logging
(trigger-happy replication, I am suspicious of the Shareplex approach
and anyway as I want to be able to replicate between France, Japan and
the US, I cannot afford to transfer full redo logs and transactions I
shall have to rollback). I log into several tables (enough info to
rebuild statements, and values separately - with additional problems
when we reach the 4,000 characters mark), IOTs are the obvious choice
but I am not sure it is available with all licenses. Degradation of my
logs over timeis also something I have to watch. This is for the days.
Evenings are spent improving an intelligent loader able to take into
account complex FK relationships. I have prepared two 5,000,000 row
tables, one in my 8.1.7 database and one in my 9.0.1 database, but I
have not tested anything yet.
I had a flash of idiocy and subscribed to the OT list (out of the
blues). I doubt I will stay long here. Some people seems to be paid
doing nothing but e-mailing. Is this where you got the details about
Pierce? Pretty active there. 
 
Cheers,
