you didn’t mention your database, but I have done things like this with a view.
I created a view with the appropriate columns and in the select statement I put in the order by
CREATE OR REPLACE VIEW myNewView AS SELECT info1, info2, theDate FROM theTable ORDER BY extract (year from theDate) desc, extract (month from theDate) asc;
A one point I actually set up some rules to make the ‘VIEW’ updatable.
YMMV obviously depending on you access to the backend, and if Views are supported.

Hi, All
I have a fetch that sorts records by three columns where one of the columns is a date (timestamp). Is there a way to sort the date by month & year only?
Thanks,
Calven
Here is the current fetch:
...
EOSortOrdering sortBySource = new EOSortOrdering("source", EOSortOrdering.CompareCaseInsensitiveAscending);
EOSortOrdering sortByAppt = new EOSortOrdering("appointmentDate", EOSortOrdering.CompareCaseInsensitiveAscending);
EOSortOrdering sortBySite = new EOSortOrdering(“site", EOSortOrdering.CompareCaseInsensitiveAscending);
NSMutableArray orderings = new NSMutableArray();
orderings.addObject(sortBySource);
orderings.addObject(sortByAppt);
orderings.addObject(sortBySite);
EOFetchSpecification spec = new EOFetchSpecification(“records", qual, orderings);
