Why is DISTINCT required was my original question.

OK making DISTINCT faster is one way of solving a speed
problem, but other simple changes to the way of working will
give even better performance improvements.

There is usually more than one way of fixing a problem, and
I like to try the alternatives rather than living with slow
performance because I got the original design wrong. I have
been there with job numbers and am just proposing an
alternative approach.
