50 QSqlCachedResult is a convenience class for databases that only allow-
51 forward only fetching. It will cache all the results so we can iterate-
52 backwards over the results again.-
53-
54 All you need to do is to inherit from QSqlCachedResult and reimplement-
55 gotoNext(). gotoNext() will have a reference to the internal cache and-
56 will give you an index where you can start filling in your data. Special-
57 case: If the user actually wants a forward-only query, idx will be -1-
58 to indicate that we are not interested in the actual values.-
