You could do "ORDER BY 1" to sort based on the first column, or you could just
remove the word "products." in both places. It should work if you say "ORDER
BY id". I would put AS id in the second select for clarity for the next reader
Incidentally, are you sure you want UNION and not UNION ALL. The former has to
exclude overlaps and that's a lot of extra work.
