C# NHibernate中一对一映射的混淆

有人可以向我建议在以下情况下使用的适当映射：

父表-所有事务

子表-TranCategory1、TranCategory2和TranCategory3及更多

所有12个表共享相同的组合键。现在count in AllTransactions是所有子表中事务的总和。子表仅包含来自父表的唯一值

我正在使用的映射如下所示

我在父表中使用constrated=“true”只是为了避免在父表的Select语句中形成联接。但我想我反对“受限”一词的定义，该词规定所有交易中的每一笔交易都必须有一笔交易在第1档。但实际上我的设计正好相反。 那么，如何修改映射以复制正确的行为并避免使用联接呢

更新：我当前的映射在联接父表和子表时引发错误。请帮助我修改映射，以便我可以对上述表执行联接

完全映射

我可以确认，只有在AccountEvent表中添加DisclosureGroupChanges的映射时，才会出现此消息。首先，我避免了这种映射，因为我得到了错误。但现在我需要在这些表之间执行联接，据我所知，我们只能对NHibernate中的相关表进行联接。如果我错了，请纠正我。

我犯了错误

子表中的一个映射的值为“LAST_MODIFIED_DATE=”。这一直是我出错的原因。

我认为您在问题中没有充分阐明表之间的关系。每张桌子上放着什么样的东西？他们关系的基本原则是什么
