> Builtin TOP function orders records in descending order. However in lot of
> cases you might want to get top N records in ascending order, such as when
> ordering records by rank, etc. The idea is to extend the TOP function so that
> it can be configured via DEFINE statement. For example
> DEFINE TOPASC TOP("ASC");
> To keep it backward compatible, the top function by default will continue to
> order in descending order.
