Excellent! That worked! Thank you once again Tom!  I was under the
impression that you couldn't use an alias in the ORDER BY.  Obviously, I was
mistaken.

Thanks,

:
: You have to use the SQL-standard syntax for ORDER BY, ie column name or
: number, no shortcuts:
:
: SELECT ..., UPPER(last_name) AS upper_last_name
: UNION
: SELECT ..., UPPER(last_name) AS upper_last_name
: ORDER BY upper_last_name;
:
: or if you prefer, ORDER BY n where n is the ordinal number of the
: column.
