I defined the domain of the NOT NULL condition:

CREATE DOMAIN AS D_PRIMARY_KEY
INTEGER NOT NULL;

I'm using it on the table in this way:

CREATE TABLE ZDARZENIA_GOSPODARCZE (
ID_ZDARZENIA D_PRIMARY_KEY,
....

However, the system table RDB$RELATION_FIELDS in the column
RDB$NULL_FLAG this item is NULL, not 1!

If the declaration will add NOT NULL:

CREATE TABLE ZDARZENIA_GOSPODARCZE (
ID_ZDARZENIA D_PRIMARY_KEY NOT NULL,
...

then the column RDB$NULL_FLAG has a valid value (1).

Does the definition of a domain should not include NOT NULL?
Is this a mistake?


ps. sorry for my poor english ;-)
