Just call Post. This is the method that causes the update/insert/delete to
occur. I have to confess that I really don't know what you are talking
about here...

Commit and post are NOT the same thing. Post is a method of the statement
object. It sends the current request to the server. You can post lots of
statements, without committing. Commit is what you do to a transaction (or
rollback, if you have a reason to).

If it was a real dataset, you wouldn't have to tell IBO, because it would
know (from the metadata it receives on preparing the statement) whether the
column is nullable or not. But a select procedure is a virtual dataset, so
there is no metadata to get, other than the types and sizes of the
arguments. So you should certainly make your application treat the data in
such a way that it won't cause exceptions when posted to a table. Hence
the absolute need, in this case, to enforce a value for inserts.
