將此SQL查詢轉換爲NHibernate標準查詢

Question

需要將此SQL查詢轉換爲nhibernate標準語言......我該怎麼做？

select 
    * 
from Feeds where Id = 
(select MAX(Id) from Feeds where DataId = [VARIABLE PARAMETER]) 

Answer 1

Feed feed = _session.CreateCriteria<Feed>() 
    .Add(Restrictions.Eq("DataId", "[VARIABLE PARAMETER]")) 
    .AddOrder(new Order("_id", false)) 
    .SetMaxResults(1) 
    .List<Feed>() 
    .FirstOrDefault(); 

，這將導致類似：

select TOP 1 * from Feeds where DataId = ??? Order By Id desc 

應該沒有從性能的角度來看difference。
