For temporary tables in temporary dbspaces, nothing is logged, not even the SQL statements that are always logged for other types of tables. If you include temporary (nonlogging) dbspaces in the value of the DBSPACETEMP configuration parameter, the database server places nonlogging tables in these temporary dbspaces first.
