There are two possible ways we can support this. The first is to have
an implicit id, for example unsigned long long with auto-assignment
semantics. In this case, while the object does not have the id member,
the table still has the id column (which is also a primary key).

The second approach is not to have the id column either. In other
words, the resulting table will not have a primary key. This is legal
from the database standpoint but somewhat unusual from the the design
perspective.

Which of the above two scenarios do you have?
