Finding duplicate objects

Hello,

I am having trouble creating a fetch specification selects duplicate objects but bases the comparison on only a few select fields. For instance a fetch specification that mimics the follow SQL query:

SELECT school_number, first_name, last_name
FROM "cms"."ms_contestant"
WHERE (contest_id = 0x000081618cb5000007d202000000011f85e471540a2b2f43
OR contest_id = 0x000081618cb5000007d204000000011f85e471540a2b2f43
OR contest_id = 0x000081618cb5000007d206000000011f85e471540a2b2f43)
GROUP BY school_number, first_name, last_name
HAVING COUNT(*) > 1

Is there a way to do this?

Regards,
Jeff
