Still a baffling thing...
- HAL, retrieve the even records please.
- cursor.execute("select * from students where id % 2 = 0")
- Now please retrieve only the ones born after the date D.
- cursor.execute("select * from students where id % 2 = 0 and dob >= %s", [D])
(some mysterious traceback)
- Open the pod bay doors, HAL.
I'd rather force people to specify % as %% regardless of the presence
of parameters (in the case of other driver the problem would be with
other characters - question marks, colons... - but it's probably the
same).

Maybe it's easy enough to use the most generic one ("%s" and
"%(name)s"? "{}" and "{name}"?) and provide a conversion library to
help implementing drivers using whatever different format they have to
use?

Yes!
