attribute, the database engine's own support for the determination of "rows
affected"/"rows selected" is quirky.
For ``DELETE`` statements, SQLite reports :attr:`rowcount` as 0 if you make a
``DELETE FROM table`` without any condition.
For :meth:`executemany` statements, the number of modifications are summed up
into :attr:`rowcount`.
As required by the Python DB API Spec, the :attr:`rowcount` attribute "is -1 in
case no ``executeXX()`` has been performed on the cursor or the rowcount of the
last operation is not determinable by the interface".

statements because we cannot determine the number of rows a query produced
until all rows were fetched.
This includes ``SELECT`` statements because we cannot determine the number of

With SQLite versions before 3.6.5, :attr:`rowcount` is set to 0 if
