Both temporal and nontemporal tables support Period data types and literals.
With respect to temporal tables:
- transaction-time columns must have a data type of PERIOD(TIMESTAMP(6) WITH TIME ZONE) or be a derived period column where the component begin and end time columns are both PERIOD(TIMESTAMP(6) WITH TIME ZONE).
- Valid-time columns can have a Period or derived period data type of PERIOD(DATE), PERIOD(TIMESTAMP[(n)]), or PERIOD(TIMESTAMP[(n)] WITH TIME ZONE).
