Nhibernate ActiveRecord映射

早上好，伙计们

我对NHibernate生成的查询有问题。我的映射如下所示：

public class Matricula
{
       [BelongsTo("IdTurma", NotNull=True)]
       public Turma {get;set;}      
}

public class Turma
{
      [BelongsTo("IdCurso", NotNull=True)]
      public Curso {get;set;}
}

public class Curso
{
       [PrimaryKey("IdCurso", Generator=PrimaryKeyType.Identity)]
       public int IdCurso{get;set;}
}

问题是：Nh生成的查询的左where应该是内部的。在Matricula和Turma之间，他们制造内部，但在Turma和Curso之间，他们制造外部。有什么问题吗？怎么了

我的问题是：

SELECT  this_.IdMatricula as IdMatric1_122_14_, 
  this_.IdTurma as IdTurma122_14_, 
  this_.IdUsuario as IdUsuario122_14_,

我们在这一点上遇到了类似的问题。为了提高性能，我们在BelongsTo属性中添加了FetchEnum.Join，这为我们带来了好处

[BelongsTo("IdCurso", NotNull = true, Fetch=FetchEnum.Join)]

迭戈，这是生成的查询。您通过NHibernate/ActiveRecord发出的查询是什么？交叉发布：我做了一个测试：ICriteria c=session.CreateCriteria（）；c、 SetFirstResult（0）、SetMaxResults（10）；ICriteria c2=CriteriaTransformer.Clone（c）；var count=c2.SetProjection（Projections.RowCount（））.UniqueResult（）；返回c.List（）；我注意到，当对象是对象父对象的子对象的子对象时，“左外部联接”是添加的。我有一个Matricula，它有Turma，它有Curso。然后在Matricula和Turma之间是NH add内部连接，但在Turma和Curso之间是NH add左外部连接。这是默认值吗？我的映射/模型有问题吗？
