/**
 * 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.
