Обсуждение: CC Date format code defaults to current centry
joe=> select to_date('19450323','CCYYMMDD'); to_date ------------ 2045-03-23 (1 row) joe=> select to_date('19450323','YYYYMMDD'); to_date ------------ 1945-03-23 (1 row) I thought the former would be "more" correct. But it seems I am mistaken.

But it seems I am mistaken. Uh, 1945 _is_ in the 20th century, but I can see how it is confusing. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 359-1001 + If your life is a hard drive, | 13 Roberts Road + Christ can be your backup. | Newtown Square, Pennsylvania 19073
