What comes to my mind is why we fool around with the diff/sort/sed/awk stuff at all.

will return all the rows in the first, but not the second. If you need further differences, transpose the select statements and put a UNION between them.

And, as an added bonus, the whole thing is on topic, no?

All praise to list admins for all they do for the community!
