如何使用nhibernate獲得隨機行？

Question

如何使用nhibernate選擇5個隨機記錄。

我的SQL是這樣的：

SELECT TOP 5 u.UserId, u.UserName, p.ImageFileName FROM users as u, profiles as p WHERE u.UserId = p.UserId ORDER BY NEWID() 

我試圖這樣做，但它不工作

IList<User> users = session 
         .CreateCriteria(typeof(User)) 
         .CreateCriteria("Profile") 
         .Add<Profile>(p => p.ImageFileName != string.Empty) 
         .AddOrder(Order.Asc("NEWID()")) 
         .SetMaxResults(5) 
         .List<User>(); 

Answer 1

您可以使用的SQLQuery：

var query = 
    "SELECT TOP 5 u.UserId, u.UserName, p.ImageFileName " + 
    "FROM users as u, profiles as p " + 
    "WHERE u.UserId = p.UserId ORDER BY NEWID()"; 

ISQLQuery qry = session.CreateSQLQuery(query).AddEntity(typeof(User)); 
List<User> rndUsers = qry.List<User>();
