SELECT part as part,
MAX(ClassWhen) as ClassWhen
FROM my_sched
WHERE ClassWhen >= 2009-12-01 00:00:00
GROUP BY part
Then if you absolutely need the associated PK[1], you can do another select:
SELECT pk_val
FROM my_sched
WHERE ClassWhen = <ClassWhen>
AND part = <part>
Note that that second select could result in multiple records if there are
multiple
part/ClassWhen combinations.
