Hi Martin,
My puzzlement is because Mike supplied a script that doesn't set the ID
column to NOT NULL and which, when he runs it, executes with no errors
when adding (with ALTER TABLE ADD CONSTRAINT) a primary key on the ID
column. I'm actually running the identical version of Firebird as Mike
is, and it fails when I try to run his (working) script.
I don't (yet) know if Mike is getting his ID column redefined silently
to be NOT NULL, I suspect so.
Cheers,
Norman.

>> Why? A primary key requires non-null columns.
