Simul-posted with David!

David, would the top-1 approach work?

Try something like this:

RdbQuery query = new RdbQuery(typeof(Case));
query.AddClause(Case.MemberIdEntityColumn, EntityQueryOp.EQ, mMember.MemberID);
query.AddOrderBy(Case.CaseDate, ListSortDirection.Descending);
query.Top = 1;
Case mostRecentCase = PM.GetEntity<Case>(query);

When you sort the cases for a member by date, descending, the top 1 record will be the most recent.

In SQL, I would use the MAX function to find the most recent case for a member.  Is there an easy way to do it with Entities and OQL or do I have to use a SQL query or stored procedure?
