How do you obtain the maximum possible date in Oracle?

Question

Is there a function built into Oracle that will return the highest possible date that may be inserted into a date field?

Answer 1

Another ways, just for fun:

SELECT to_date(5373484, 'J') + (1 - 1/24/60/60)
  FROM dual;

SELECT date '9999-12-31' + (1 - 1/24/60/60) 
  FROM dual;
