That's right. If you do not declare the column with a constraint of NOT
NULL, then it is not an error to do:

insert into table_1 (field_1,field_2)  values ('f1_value',10);

Why should this query throw an error? You are asking the DB to insert
values into a row. There are no constraints on any of the columns so the
DB is quite happy to do what you ask.

If you want to make it mandatory for an insert to specify a value for a
column then you MUST have a constraint on that column of NOT NULL.
