ADD_MONTHS observes the following rules:

  • If either argument of ADD_MONTHS is NULL, then the result is NULL.
  • If the result is not in the range ‘0000-01-01’ to ‘9999-12-31’, then an error is reported.
  • Results of an ADD_MONTHS function that are not valid dates are normalized to ensure that all reported dates are valid.
