Only get latest results using nHibernate

Question

I have a nHibernate query like this

ICriteria query = session.CreateCriteria(typeof(MyResult))
            .Add(Expression.Eq(\"ResultTypeId\", myResult.Resu         


        

Answer 1

You can order the result by ResultDate using the AddOrder method, as below:

ICriteria query = session.CreateCriteria(typeof(MyResult))
        .Add(Expression.Eq("ResultTypeId", myResult.ResultTypeId))
        .AddOrder(Order.Desc("ResultDate"))
        .List();

If you want to limit the number of MyResult instances you get back, you can use the SetMaxResults method, like so:

ICriteria query = session.CreateCriteria(typeof(MyResult))
        .Add(Expression.Eq("ResultTypeId", myResult.ResultTypeId))
        .AddOrder(Order.Desc("ResultDate"))
        .SetMaxResults(20)
        .List();
