Nhibernate 无纤维的或存在的

将以下内容转换为Sql到nhibernate时遇到问题：

SELECT DISTINCT Booking.*
FROM   Booking WHERE  Booking.Status = 2
            OR EXISTS (SELECT 1
            FROM   JourneyFuture
            WHERE  JourneyFuture.BookingId = Booking.BookingId
                    AND ((JourneyFuture.[IsDriverAssigned] = 0
                        AND JourneyFuture.[Status] = 1) -- live
                        OR JourneyFuture.[Status] = 2
                        OR JourneyFuture.[Status] = 4
                        OR (JourneyFuture.[Status] = 1
                            AND (JourneyFuture.IsMetricCalculated = 0
                                    OR JourneyFuture.Duration = 0
                                    OR JourneyFuture.Distance = 0))))

Booking bookingAlias = null;    
var journeyFuture = QueryOver.Of<JourneyFuture>().Where(x=> x.Booking.Id==bookingAlias.Id).
                    And(x => (!x.IsDriverAssigned && x.Status==JourneyStatusType.Live) || x.Status==JourneyStatusType.CancelRequested
                                || x.Status == JourneyStatusType.Modified || 
                                (x.Status == JourneyStatusType.Live && (!x.IsMetricCalculated || x.Duration==0 || x.Distance==0)))
                                .Select(x=> x.Booking);

                var result = session.QueryOver<Booking>(() => bookingAlias)
                    .Where(x => x.Status == BookingStatusType.CancelRequested)
                    .WithSubquery.WhereExists(journeyFuture)
                    .List<Booking>();

以下是我到目前为止对Nhibernate的了解：

SELECT DISTINCT Booking.*
FROM   Booking WHERE  Booking.Status = 2
            OR EXISTS (SELECT 1
            FROM   JourneyFuture
            WHERE  JourneyFuture.BookingId = Booking.BookingId
                    AND ((JourneyFuture.[IsDriverAssigned] = 0
                        AND JourneyFuture.[Status] = 1) -- live
                        OR JourneyFuture.[Status] = 2
                        OR JourneyFuture.[Status] = 4
                        OR (JourneyFuture.[Status] = 1
                            AND (JourneyFuture.IsMetricCalculated = 0
                                    OR JourneyFuture.Duration = 0
                                    OR JourneyFuture.Distance = 0))))

Booking bookingAlias = null;    
var journeyFuture = QueryOver.Of<JourneyFuture>().Where(x=> x.Booking.Id==bookingAlias.Id).
                    And(x => (!x.IsDriverAssigned && x.Status==JourneyStatusType.Live) || x.Status==JourneyStatusType.CancelRequested
                                || x.Status == JourneyStatusType.Modified || 
                                (x.Status == JourneyStatusType.Live && (!x.IsMetricCalculated || x.Duration==0 || x.Distance==0)))
                                .Select(x=> x.Booking);

                var result = session.QueryOver<Booking>(() => bookingAlias)
                    .Where(x => x.Status == BookingStatusType.CancelRequested)
                    .WithSubquery.WhereExists(journeyFuture)
                    .List<Booking>();

bookingAlias=null；
var journeyFuture=QueryOver.Of（）。其中（x=>x.Booking.Id==bookingAlias.Id）。
和（x=>（！x.IsDriverAssigned&&x.Status==JourneyStatusType.Live）| | x.Status==JourneyStatusType.CancelRequested
||x.Status==JourneyStatusType.Modified | |
（x.Status==JourneyStatusType.Live&（！x.IsMetricCalculated | | x.Duration==0 | | x.Distance==0）））
.选择（x=>x.Booking）；
var result=session.QueryOver（（）=>bookingAlias）
.Where（x=>x.Status==BookingStatusType.CancelRequested）
.WithSubquery.WhereExists（journeyFuture）
.List（）；

然而，这产生了一个有意义的“和”存在，但是我如何获得一个或存在

感谢您的帮助。

以下几点应该有效：

Booking bookingAlias = null;    
var journeyFuture = QueryOver.Of<JourneyFuture>().Where(x=> x.Booking.Id==bookingAlias.Id).
    And(x => (!x.IsDriverAssigned && x.Status==JourneyStatusType.Live) || x.Status==JourneyStatusType.CancelRequested
                || x.Status == JourneyStatusType.Modified || 
                (x.Status == JourneyStatusType.Live && (!x.IsMetricCalculated || x.Duration==0 || x.Distance==0)))
                .Select(x=> x.Booking);

var result = session.QueryOver<Booking>(() => bookingAlias)
    .Where(
        Restrictions.Or(
            Restrictions.Where(() => bookingAlias.Status == BookingStatusType.CancelRequested),
            Subqueries.Exists(journeyFuture.DetachedCriteria)))
    .List<Booking>();

bookingAlias=null；
var journeyFuture=QueryOver.Of（）。其中（x=>x.Booking.Id==bookingAlias.Id）。
和（x=>（！x.IsDriverAssigned&&x.Status==JourneyStatusType.Live）| | x.Status==JourneyStatusType.CancelRequested
||x.Status==JourneyStatusType.Modified | |
（x.Status==JourneyStatusType.Live&（！x.IsMetricCalculated | | x.Duration==0 | | x.Distance==0）））
.选择（x=>x.Booking）；
var result=session.QueryOver（（）=>bookingAlias）
.在哪里(
限制。或(
限制。其中（（）=>bookingAlias.Status==BookingStatusType.CancelRequested），
子查询.Exists（journeyFuture.DetachedCriteria）））
.List（）；

基本上用更强大的

限制替换
.WithSubquery
。或

和

子查询。存在

。我希望有一种方法可以用

.WithSubquery

，但我不确定是否有

一般来说，对于复杂的限制，您可以深入到

限制

类。这样做的缺点是通常会使代码更复杂。

谢谢Andrew，这正是我想要的。@Paddy:没问题！很乐意帮忙！
