How to get a distinct result with nHibernate and QueryOver API?

Question

I have this Repository method

    public IList ListMessagesBy(string text, IList tags, int pageIndex, out int count, out int pageSi         


        

Answer 1

If you're using the ICriteria API, you need:

.SetResultTransformer(new DistinctEntityRootTransformer())

If you're using the QueryOver API, you need:

.TransformUsing(Transformers.DistinctRootEntity)

But beware, this all occurs on client side, so all the duplicate rows are still pulled.
