    Description

      From HIVE-16575:

      SQL:2011 spec, 10.8, uses [ NOT ] ENFORCED for column constraint characteristics.
      I think Oracle invented DISABLE and NORELY and maybe others have copied it over time.
      A quick check I see DB2 uses the [ NOT ] ENFORCED. Teradata uses something else entirely.
      Personally I think there are advantages to adopting the standard approach.
      There is no standard approach for hinting the optimizer so we're on our own there.
