The Update operator can load data into temporal tables using the Extended MultiLoad Protocol. The job automatically uses the Extended MultiLoad Protocol when the job is loading into temporal tables. The temporal tables can be of two kinds: 1) Teradata Temporal or 2) ANSI Temporal.
The column schema USINGEXTENSION option must be used to load temporal tables. The Update operator does not validate the value for the USINGEXTENSION option. The database validates the value.
