Subject: Validity check in to_date?
Date: Thu, 27 Nov 2003 17:11:25 +0300
Message-ID: <20031127141125.GC87728@dyatel.antar.bryansk.ru> (raw)
I just discovered that to_date() function does not check if supplied
date is correct, giving surprising (at least for me) results:
fduch=# SELECT to_date('31.11.2003', 'DD.MM.YYYY');
to_date
------------
2003-12-01
or even
fduch=# SELECT to_date('123.45.2003', 'DD.MM.YYYY');
to_date
------------
2007-01-03
to_timestamp() seems to work the same way. It's probably useful sometimes,
but not in my case... Is it how it supposed to work?
If so, how can I do such a validity check?
If not, has something changed in 7.4?
In any case, I have to find a workaround now and will appreciate any help.
fduch=# SELECT version();
version
