Questions about temporary tables
I'd like to use temp tables for storing results that will be used in sub-queries. Is there table variables in Vertica? Basically, I need to create the temp table(table variable) and insert data to be used in sub-queries, and after the main query is done, the temp table (table variable) should be gone . Is Vertica local temp table in memory or on disk? Does it clean up after itself (destroy itself) when the session is done?
