How do you obtain the maximum possible date in Oracle?


SELECT  TO_DATE('31.12.9999 23:59:59', 'dd.mm.yyyy hh24:mi:ss')FROM    dual

Note that minimal date is much more simple:

SELECT  TO_DATE(1, 'J')FROM    dual


From the 11g docs:

Oracle Database can store dates in the Julian era, ranging from January 1, 4712 BCE through December 31, 9999 CE (Common Era, or 'AD').
