Questions tagged [temp-tables]
Temporary tables are a feature of RDBMS's as a means of storing intermediate results. Some RDBMS's make the distinction between local and global temporary tables. Temporary tables are typically dropped when the session ends for local, or when the temporary table is no longer referenced for global. Note that a temporary table is not the same as a table variable even though both are temporary in nature.
