I think is senseless to drop a temporary table every time, becauase it
implies adittional unnecesary recursive work.
So I personally don't understand why to expect a temporary table should be
droped and recreated.
There is no overhead in keeping a temporary table.

I believe that the guy who asked the question expected the table to be gone
when the session logs out, but it isn't the case. Global temporary tables
are
nothing like the temporary tables from SQL server, which vanish when the
session
is done. I don't think that creatig/dropping tables at the end of the
session is
a good idea. I'm using GTT in several of my perl scripts in such a way that
I first
load data into a GTT and then run a PL/SQL procedure to transform the data
into the
required format, but I don't drop them. Most of those perl scripts are run
from cron.
