Global temporary tables
All data stored in a global temporary table is private to
the session that has inserted (or updated) it.
Other sessions can't see this data. Global temporary tables
come in two flavors:
on commit preserve rows and on commit delete rows.
DDLs (such as drop table) on a on commit preserve rows lead
to a ORA-14452
when the session has already made a DML on the table.
Object tables
