Why not just set the day value to '00' if you don't have a value, and
then check that in your client code? That way, no extra columns. I.e. if
you don't have a day value, then your DATE will be
$sale-date-year . - . $sale-date-month . -00, or whatever.

What I'm trying to understand is how you would set up these
indexes when you'd always be doing joins with another table.
Suppose you have The Canonical CD Database
column in this index. The experiments I've done
so far have been inconclusive, and I don't think I'm understanding
the process in the first place.
Thanks very much.
