StoreQueryResult::operator returns Row&. Row::operator returns
const String&. String has member is_null() today, but until the next
version of MySQL++, doesn't have operator==(mysqlpp::null_type), the
type of mysqlpp::null. Thus, it can't be tested as null in this way.
(at() is the same as operator() in StoreQueryResult and Row, so you
can substitute it in above where you like.)
