* A transient table is a named table that may come into existence implicitly during the
* evaluation of a query expression or the execution of a trigger. A transient table is
* identified by a query name if it arises during the evaluation of a query expression,
* or by a transition table name if it arises during the execution of a trigger.
* Such tables exist only for the duration of the executing SQL-statement containing the
* query expression or for the duration of the executing trigger.
