Wait wait wait! I see what you mean. What I'm seeing as a loop (rows upon
rows of data from the database) is a single query to MySQL. So it's fist
selecting, then calculating my variable, then sorting. And in sorting, I see
"wrong" values for my "is different from the previous" pseudo field.
Glact.
Is there anything I can do to get the functionality I'm after in any other
way? I seem to remember there's a "having" clause which gets computed in the
end?
L.A.
