美好的一天！
我们的EF数据模型中有TPT继承，基于数据库中的视图集和存储过程。有基本实体标记，它不是抽象的，具有主键TtrId和继承的实体 FinancialGoal 。 标记实体基于视图vwTagTree， FinancialGoal 基于视图vwGoals。两个视图都具有字段TtrId一对一实现关系。每个实体都与其他模型实体相关联。实体标记的字段TtrId具有属性StoreGeneratedPattern = Identity，但它不作为依赖字段参与任何关联。
但是，我们收到错误“ ReferentialConstraint中的依赖属性映射到存储生成的列。列：'TtrId'。”，同时尝试添加 FinancialGoal 对象。选择正常，更新正常，插入标记对象即可，但插入 FinancialGoal 对象会引发上述错误。
以下是EF模型图的一部分：
遗憾的是，由于信誉不佳，我无法发布截图，因此这是EDDL定义的CSDL部分：

任何帮助表示感谢。
答案 0 :(得分：0)
听起来你已经按照相反的顺序映射了某些实体之间的依赖关系，并且EF认为TtrId中的Tag是外键 - EF中的外键不能将StoreGeneratedPattern设置为Identity或Computed。
