Rico commented on HHH-2381:
---------------------------

Is it possible to refactor Order to simplify writing db specific Order class (typically for NLS_SORT in Oracle)? For instance, by changing the visibility of fields ascending, ignoreCase & propertyName (protected instead of private) ;

> Hi,
> It would be nice to be able to specify the ORDER BY clause using Native SQL. (It is currently doable by subclassing the Order class, but some nice solution would allow the order to specify attributes on another table..)
> Let's take a simple example : I have a distance("attribute", geometry) function, that is of course, proprietary.
> I am quering table A, which I can join to table B to get the "attribute", on which I want to apply my distance() function.
> If I create my own Order subclass, and addOrder on the criteria, the  distance("attribute, geometry) is going to refer to the main criteria's class mapping. 
> So, something like addOrder("objectpath.joined", new MyOrder(...)); would be perfect.
> What do you think ?
> Regards,
> Sami Dalouche
