Обсуждение: null value in date field

I have a form that contains optional DATE fields.  To enter null
values, I've tried null, 'null', '', '-', '0', 0, and each time I get
the following error:

ERROR:  Bad numeric input format ''

Is there a correct way to enter null values into DATE fields?

Thanks,
Jeff Deroshia

Are you sure this is on a date field?  Date should be giving you
something like (at least in 7.3):
 ERROR: Bad date external representation ''

Null works for me...
sszabo=# create table test(a date);
CREATE TABLE
sszabo=# insert into test (a) values (null);
INSERT 4256129 1
sszabo=# insert into test (a) values ('');
ERROR:  Bad date external representation ''

NULL outside of quotes.
