linq-to-nhibernate - linq-to-nhibernateでのhql合体に相当

Question

私が次のhqlを持っていると仮定します：

select cast(coalesce(sum(c.Valoare), 0) as decimal)
      from Comision as c
      where c.User = :user

Linq-To-Nhibernateでこれを書く方法はありますか？

Answer 1

C# null 合体演算子を使用できますか?

(from c in Comision
where c.User = user
select c.Valoare ?? 0).Sum()
