Oops, forgot about this email.

Two things come to mind:

- is the driver required to do an implicit cast from VARCHAR to random
other types (e.g. setString() used against a smallint column); the spec
says nothing about this, and it's inconvenient for us to support, but
many people seem to expect it.

- is PreparedStatement.setObject(i,null) allowed? It's the only way to
sneak an untyped parameter in and seems like an oversight. If it's
allowed, what's the equivalent setNull() call that it corresponds to?
