ANSI supports special CREATE TABLE and ALTER TABLE syntax for creating valid-time tables. Creating temporal tables includes:

  • Defining the beginning and ending bound columns for the valid-time period
  • Defining the VALIDTIME derived period column
  • Optional syntax to define primary key, unique, and referential constraints for ANSI valid-time tables.
