Thanks guys.  Hmm.  Both of these work if I use the DISTINCT keyword.  
But for some reason, such things as DISTINCT COUNT(name) don't work, 
and each copy goes toward the total.  I can't really afford to fetch 
all the results and count them on the client side.  I shouldn't have 
used the word "list", my mistake.

Hmm.  Looks like the inner join does the same thing--or were these 
other queries already implicitly inner joins?  I really dislike 
databases. :-)

So it's not a list I need, but a count.  Hrmm.

I bet I need sub-selects.  Something like   SELECT COUNT(*) FROM ( 
SELECT DISTINCT )

Thanks for your help.  I'm going to keep banging my head against it.
