Can any temporary tables be created that automatically get dropped at the close of an instance?
What you are looking for in Oracle is called a Global Temporary Table. The CREATE GLOBAL TEMPORARY TABLE statement creates a temporary table. This table holds data that can be transaction-specific or session-specific. From the Oracle docs, "For transaction-specific temporary tables, data exists for the duration of the transaction. For session-specific temporary tables, data exists for the duration of the session. Data in a temporary table is private to the session. Each session can only see and modify its own data." The temporary table will always exist, but the data inside will only survive for the duration of the session or transaction. This way, all of your application users can use this same global temporary table, only see their data, and the data only lives temporarily inside the database.
