C# nhibernate joinqueryover无关表（相同外键）

基本上我要做的就是用外键连接两个表。我有一个疑问：

        var result =
            _session.QueryOver(() => contentReferenceAlias)
                    .Inner.JoinAlias(() => contentReferenceAlias.ContentReference, () => contentLibrarySearchAlias.ContentReference)
                    .Where(() => contentReferenceAlias.ToLanguage.Id == languageId && contentReferenceAlias.ContentReference.Id == contentLibrarySearchAlias.ContentReference.Id)
                    .SelectList(list => list
                                            .Select(() => contentReferenceAlias.ContentReference)
                                            .Select(() => contentLibrarySearchAlias.ContentReference)
                                            .Select(() => contentReferenceAlias.ContentReference.Id).WithAlias(() => resultAlias.ContentReferenceId)
                                            .Select(() => contentReferenceAlias.ContentReference.Id).WithAlias(() => resultAlias.ContentReferenceId)
                                            .Select(() => contentReferenceAlias.OrderedFrom).WithAlia

我正在尝试重新创建的SQL语句：

  SELECT A.OrderedFrom, C.LastOrdered, A.ContentReferenceId, B.Title FROM TranslationContentReference A
  INNER JOIN TranslationOrder C ON (A.TranslationOrderId = C.Id)
  INNER JOIN ContentLibrarySearch B ON (A.ContentReferenceId = b.ContentReferenceId)
  WHERE A.ToLanguageId = 'xxxx-xxxx-xxxx-xxxx-xxxx'

如果我确实正确理解了您的场景，那么不能通过QueryOverAPI实现中间人（外键引用）的连接。NHibernate需要知道所有路径，因此如果没有从

TranslationContentReference

到

ContentReference

到

ContentLibrarySearch

的显式映射，那么我们就无法创建正确的JoinAlias

因此，第一种选择是扩展中间人对象

public class ContentReference
{
    ...
    public virtual IList<TranslationContentReference> TranslationContentReference { get; set;}
    public virtual IList<ContentLibrarySearch> ContentLibrarySearch { get; set;}
}

我选择了createsqlquery选项，这是实现目标的最快方法，因为性能是实现这一目标的全部原因，这似乎是最好的主意。谢谢你的回答，也谢谢你证实我是在尝试做一些“不可能”的事情。是的，这是正确的。通过NHibernate基础设施（结果转换器）实现的有点复杂的SQL语句。如此强大；）

ISQLQuery query = session.CreateSQLQuery(
  "SELECT A.OrderedFrom, C.LastOrdered, A.ContentReferenceId, B.Title 
    FROM TranslationContentReference A
     INNER JOIN TranslationOrder C ON (A.TranslationOrderId = C.Id)
     INNER JOIN ContentLibrarySearch B ON (A.ContentReferenceId = b.ContentReferenceId)
    WHERE A.ToLanguageId = :language");
query.SetString("language", "xxxx-xxxx-xxxx-xxxx-xxxx");
var result = query.SetResultTransformer(new AliasToBeanResultTransformer(typeof(MyDTO)))
.List();
