The not "Max" records

Hello,
I have a query that finds all records with a particular "Case#". I changed
the query to do totals and grouped by Case#'s. I have another field called
"PrisonID" in which I want to see all records except for the Max (except the
highest number PrisonID). Eventually I need to change this query into a
delete query so that it automatically deletes all duplicate records with the
lowest PrisonID.
Can you help me figure this out?

Thanks.

Are you saying you want to delete all records for each case EXCEPT for the one
with maximum PrisonID?

STEP 1: BACKUP your data before attempting the following.
STEP 2: BACKUP your data before attempting the following.

Without a backup you cannot restore the data if this does not work the way you
expect.

The following could be slow

DELETE
FROM SomeTable
WHERE PrisonID
(SELECT MAX(PrisonID) FROM SomeTable as T
WHERE T.[Case#] = SomeTable.[Case#])
