    How can I order data descending with null on the end?

    In SQL I can do it:
    select r
    from some_table AS r
    order by r.some_column DESC NULLS LAST


    In OQL it's not working:
    select r
    from r.some_tableExtent
    order by r.some_column DESC NULLS LAST

    What can I do instead?

    At the moment i see no way to express that via OQL. It also seems to be an Oracle specific extension of SQL.
    Using LINQ, you could emulate this behavior by using
    .OrderBy(x => x.Property != null ? 0 : 1).ThenBy(x => x.Property)
