将属性映射到NHibernate中另一个表中的字段 [英] Mapping a property to a field from another table in NHibernate

问题描述

考虑以下类：

consider the following class:

class Order {
    int OrderId {get; set;}
    int CustomerId {get; set;}
    string CustomerName {get; set;}
    //other fields go here
}

映射订单表。是否有可能通过外键关系将属性CustomerName映射到Customers表？

which is mapped to Orders table. Is it possible to map the property CustomerName to the Customers table through the foreign key relation?

推荐答案

是的，您可以使用<一个href =http://ayende.com/Blog/archive/2009/04/20/nhibernate-mapping-ltjoingt.aspx =nofollow noreferrer>加入映射元素。另一种选择是映射视图而不是表格。但如果可能的话，您应该采用面向对象的方法，并映射Order和Customer之间的多对多关系。

Yes, you can use the join mapping element for this. Another option is to map a view instead of a table. But if possible you should take the object-oriented approach and map the many-to-many relationship between Order and Customer.
