A Local temporary table exists only for the duration of a connection or, if defined inside a compound statement, for the duration of the compound statement.

A Global temporary table remains in the database permanently, but the rows exist only within a given connection. When connection is closed, the data in the global temporary table disappears. However, the table definition remains with the database for access when database is opened next time.
