IMHO adding an extra switch is not the Best Solution, because it adds
complexity. On the other hand, if that is what it takes... The RDBMS I
used when I got hit by the problem was Oracle 9i. It might be worth
the effort to investigate whether any major RDBMses fails to support
the use of aliases in ORDER BY clauses.
