how to create a readonly session in nHiberate ?

Question

Is it possible to creat a readonly connection in nHibernate ?

Read-only : where nHibernate will not flush out any changes to the underlying database implicitly or explicitly.

When closing a nhibernate connection it does automatically flush out the changes to the persistent object.

Setting the flush mode to never is one way - but is reversable (i.e some code can reset the flush mode).

Answer 1

I think you've already found the solution, setting flush mode to never. Yes, it is changeable but even if it wasn't, code could simply create another session that had a different flush mode.

I think the appropriate solution is to suggest read-only with session.FlushMode = FlushMode.Never and enforce it by using a connection to the database that only has SELECT permissions (or whatever is appropriate for your situation). Maintaining separate ISessionFactory factories might help by allowing something like ReadOnlySessionFactory.Create().
