Thread: date validation problem
sir,
in postgresql 7.3.2 when we are trying to query like
select to_date('665555555','ddmmyyyy');
the output is
5559-09-06
it is not validating the day and month and unknown format
is the output..
any help regarding this is greatful...
thank you
I don't see the problem... you are specifying the 66th
day of the 55th month in the year 5555. just a cursory
glance says that 48 months is 4 years... that gives
the year as 5559. try your example with real numbers
(unless these are real)
select to_date('13122003','ddmmyyyy');
to_date
------------
2003-12-13

(Assuming a typo, the select() showed the 665th day).
But there is no 55th month and no 66th day of that month,
the conversion should simply fail and abort the transaction
with an error, shouldn't it ?

I believe this is an acknowledged bug in to_date, which Karel hasn't
yet got around to fixing.
