EJBQLQuery will support that. I really hope we reconcile it with SelectQuery, as now it has to be created from String.

Sorry, I misread your question.   You really want to do an ordering by
expression rather than by column.

There is a thread on this.

The short answer is that it's not supported.   There are a number of
workarounds, depending on the specific query and how you need to use
it.

In your specific case, perhaps you could create a view containing A+B
as an additional column and sort on that column.

Or you can use an SQLTemplate to create the query.

I believe there were other workarounds in the thread above.

the way

The generated SQL must be something like "SELECT A, B FROM T ORDER BY A
+ B";

Sorry for my bad english
Thanks in advance
