If you do happen to need each part of the result set ordered individually, you can do something like the following:
SELECT 1,A,B,C FROM TABLEABC UNION SELECT 2,D,E,F FROM TABLEDEF ORDER BY 1,2 Bizarre as it may seem, I've used this technique to good effect many times in the past. Basically, I once worked on a a set of reports where I had to return all results in one query (tool limitation) and I need to generate different "sections" in a single report. To do that, I used the technique above.
