Greetings,
I am finally adding Null support to my dbf package
(http://pypi.python.org/pypi/dbf) and, as usual, the VFP side is being a
pain.
The issue is that the Logical, Date, and DateTime field types, even when
the table does not allow Null values, can be empty -- and when Null
values are allowed, those fields can be empty or Null. (Empty pretty
much meaning not initialized -- neither True nor False, and no Date nor
Time.)
At this point, also, my module does not support the DB API (that is a
goal though), so right now you pretty much get direct access to the
physical table.
My question: for the direct access side, is there any advantage to
treating an empty L, D, or T field differently from a Null L, D, or T
field? Or should they be semantically the same, always returning, for
example, None whether it's actually Null in the table or just empty?
