C# 将SQL查询转换为NHibernate查询

我有这两张桌子

AppUser

主键：用户标识

用户原则

public UserPagedQuery(ISessionProvider<ISession> sessionProvider)
{
    _sessionProvider = sessionProvider;
    _query = sessionProvider.Session.QueryOver<IUser>();

    var uc = _query.UnderlyingCriteria;
    var ap = uc.GetOrCreateAssociationPath("StoredCredentials");
    ap.AddOrder(Order.Asc("UserName"));
}

public IEnumerable<IUser> Execute()
{
    var pagedReceiving = _query.TransformUsing(Transformers.DistinctRootEntity).List<IUser>();
    return pagedReceiving;
}

用户ID（不是此表中的键）

用户名

我需要在NHibernate中使用分页进行此查询： 我现在的相关代码是： （IUser代表的AppUser；StoredCredentials代表的UserPrinciples）

这还不够好，因为我只需要每个用户id中的一条记录，对于某些用户，通过这个查询我可以获得多条记录，这就是问题所在

有人能帮忙吗？ 不确定是否需要任何其他细节

表示为不带分区的sql

SELECT TOP(page_size) up.*, au.* from
  (SELECT UserName, Min(User_Id) as User_Id FROM UserPrinciples GROUP BY UserName) as x
LEFT JOIN
  UserPrinciples up ON x.UserName = up.UserName AND x.User_Id = up.User_Id
LEFT JOIN
  AppUser au ON  au.User_Id = up.User_Id

翻译成linq应该是这样的：

var y = from up1 in session.Query<Employment>()
        group up1 by up1.Name into g
        select new { Name = g.Key, UserId = g.Min(x => x.Company.Id) } into f
        join up2 in session.Query<Employment>() on new { f.Name, f.UserId } equals new { up2.Name, UserId = up2.Company.Id }
        select new SomeDto
        {
            ProfileName = up2.Name,
            UserId = up2.User.Id,
            Name = up2.User.Name,
        };

var results = y.ToList();

var y=来自会话中的up1.Query（）
按up1将up1分组。将名称放入g中
在f中选择新的{Name=g.Key，UserId=g.Min（x=>x.Company.Id）}
在新{f.Name，f.UserId}上的session.Query（）中加入up2等于新{up2.Name，UserId=up2.Company.Id}
选择要添加的新内容
{
ProfileName=up2.Name，
UserId=up2.User.Id，
Name=up2.User.Name，
};
var结果=y.ToList（）；

SELECT TOP(page_size) up.*, au.* from
  (SELECT UserName, Min(User_Id) as User_Id FROM UserPrinciples GROUP BY UserName) as x
LEFT JOIN
  UserPrinciples up ON x.UserName = up.UserName AND x.User_Id = up.User_Id
LEFT JOIN
  AppUser au ON  au.User_Id = up.User_Id

var y = from up1 in session.Query<Employment>()
        group up1 by up1.Name into g
        select new { Name = g.Key, UserId = g.Min(x => x.Company.Id) } into f
        join up2 in session.Query<Employment>() on new { f.Name, f.UserId } equals new { up2.Name, UserId = up2.Company.Id }
        select new SomeDto
        {
            ProfileName = up2.Name,
            UserId = up2.User.Id,
            Name = up2.User.Name,
        };

var results = y.ToList();
