Обсуждение: Valid Input Syntax for Type DATE

   I'm trying to insert rows into a table, but some date and time columns are
missing values. In the INSERT INTO ... statements of the .sql file I've
tried various formats: ,, and ,'', and ,' ', but they all generate the error
of invalid syntax for type date.

   When I have missing date of the date and time types, how do I validly
represent them in the input file?

If the column is null'able, I think you can use the keyword: DEFAULT

insert into(id, xdate) values (1, DEFAULT);

Not 100%, but I think so.

Or... use NULL:

insert into(id, xdate) values (1, NULL);

NULL works, but one advantage of using DEFAULT is that you won't have
to worry which columns are set to NOT NULL.  This assumes that the NOT
NULL columns have default values assigned to them, which is a good
idea.

   Thank you both.
