Hi,
I have a table with a column like:
date date default null,
If I enter an empty string in it, the default null value is added (as it
should).
But if I enter an invalid date by mistake, the date -00-00 date date
is entered instead of the default null, and this is not good.
Can I do
Hi Octavian,
One approach is to use a trigger,
mysql> set sql_mode = '';
mysql> create table temp_date(d date default null);
mysql> create trigger temp_date_bi before insert on temp_date for each row set
new.d = if(new.d = '-00-00', null, new.d);
mysql> insert into temp_date(d) values('20
