do all 4 work?

[echo]

yes
but it has to set primary key with auto increment

[kqr]

if you set it to default value how does it know to persist instead of merge?

[echo]

there are several way to check persisted.
i prefer set Transactional and dirty checking.
maybe it cannot check on code, it is going wrong way i think.
