在表中使用不带主键/唯一键的Fluent nHibernate

Question

In my database table I don't have any primary or unique keys. I am using an Oracle database table.

1.Can I use Fluent nHibernate without primary or unique key?

2.If I can use it, how do I do the mapping? Because when Id is not mapped it throws an exception.

Answer 1

Possible duplicate of Fluent-NHibernate table mapping with no primary key .

AFAIK all ORMs need a primary key. The main reason I see is to manage dirty tracking and caching mechanisms in session.

Also, there is no reason for you NOT to have a primary key in your table. Even if you think you don't need one, stick a auto incremented int column as the key and you should have no problems.

Answer 2

If you are using oracle try to use "ROWID". But in my opinion If you don't have any primary or unique keys then better use your own ORM for your requirement.
