实体框架映射存在于两个数据库中的同一个表 [英] Entity Framework map same table that exists in two databases
问题描述
使用实体框架正确映射以下内容有哪些选项:
What options are available to correctly map the following using Entity Framework:
数据库1表:
Foo,Foo_Assets,Assets
Database 1 tables: Foo, Foo_Assets, Assets
数据库2表:
Bar,Bar_Assets,Assets
Database 2 tables: Bar, Bar_Assets, Assets
我已经将映射栏,Bar_Assets,Assets作为SQL视图,或者从数据库2加载这些表时使用不同的数据库上下文。
I have considered mapping Bar, Bar_Assets, Assets as SQL views, or using a different db context when loading these tables from Database 2.
挑战是尽管Foo,Bar及其_Assets表可以单独对待,但两个数据库都具有资产表。这些表如何正确映射到资产实体?
The challenge is that although Foo, Bar and their _Assets tables can be treated independently, both databases have an Assets table. How can these tables be correctly mapped to the Asset entity?
推荐答案
由于您有2个数据库,您将拥有2个edmx文件。只有在edmx中使用不同的名称才能使用资产表。这样就可以确保没有冲突。
Since you have 2 databases, you will have 2 edmx files. Just having a different name in the edmx for Assets table will work. This way you can ensure that there are no clashes.
