Sorry for the distraction, cried to soon...
I was refering to the NULL in primary key columns feature of SQLite as
documented in:
http://sqlite.org/lang_createtable.html
"According to the SQL standard, PRIMARY KEY should imply NOT NULL.
Unfortunately, due to a long-standing coding oversight, this is not the case
in SQLite. SQLite allows NULL values in a PRIMARY KEY column. We could
change SQLite to conform to the standard (and we might do so in the future),
but by the time the oversight was discovered, SQLite was in such wide use
that we feared breaking legacy code if we fixed the problem. So for now we
have chosen to contain allowing NULLs in PRIMARY KEY columns. Developers
should be aware, however, that we may change SQLite to conform to the SQL
standard in future and should design new programs accordingly."
So basically i missed the point as you don't insert into the PK column.
