Rick,
Thanks! Here is the create table info. Sorry for the size, but you can skip
down from all the fields to see the indexes.
CREATE TABLE `exams` (
`zAddDate` date DEFAULT NULL,
`zModDate` date DEFAULT NULL,
`IdPatient
of key_buffer_size? It should generally be 20% of _available_
RAM (for MyISAM usage).

I have a query I'm having trouble with. If do this query which is DATE plus
ProcModecode, it is very fast:
SELECT e.zzk FROM exams e
-- JOIN Appt_ a ON e.IdAppt = a.IdAppt
-- JOIN Affil_ af ON a.IdAffil_primary = af.IdAffil
WHERE e.dateexam = '2012-09-01' AND e.dateexam = '2012-09-30'
AND

) -- in that order
(I can't predict which index it would use.)
Are IdAppt the same datatype and collation in each table?
