Criteria API : Order by Native SQL 
-----------------------------------

         Key: HHH-2381
         URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2381
     Project: Hibernate3
        Type: Improvement

  Components: query-criteria  
    Reporter: Sami Dalouche


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
