问题描述
您好，这是我的问题：
我有两个表亲属（IDRelative为Key，Name等）和Residents（IDResident为密钥，IDSignal，IDTypeSignal等）
>我想建立一个关系IDResident - > IDSignal或IDRelative - > IDSignal是IDTypeSignal值的函数。
如果IDTypeSignal = 1则关系将是IDResident - > IDSignal
如果IDTypeSignal = 2那么关系将是IDRelative - > IDSignal
如果IDTypeSignal = -1则没有关系。
我想用EntityFramework建模这种关系，但我不确定如果这种关系可以做到。
有可能建模吗？
谢谢。
Hello, here is my question:
I have two tables Relatives (with IDRelative as Key,Name etc) and Residents (with IDResident as key, IDSignal, IDTypeSignal and so on)
I want to make a relation IDResident --> IDSignal or IDRelative --> IDSignal in function of the value of IDTypeSignal.
If IDTypeSignal = 1 then the relation will be IDResident --> IDSignal
If IDTypeSignal = 2 then the relation will be IDRelative --> IDSignal
If IDTypeSignal = -1 then there is no relation.
I want to model this relations with EntityFramework but I´m not sure If this kind of Relations are possible to do.
Is that possible to model?
Thank you.
