Sorry for the ambiguity, I was trying to make a really generic select
statement. I just meant that if 'where a = A.a' has no matches, but 'where
b = B.b' or 'where c = C.c' does match, the query returns what did match,
and just returns null where it didnt. I will look at the CASE WHEN...THEN.
Thanks!

You'll have to be more specific in your example -- your select statement
below is rather ambiguous.
However, take a look at the CASE WHEN...THEN functions that MySQL offers.
I'm sure it's exactly what you are looking for.
