NHibernate ISession.Delete

Question

I know it´sa pretty simple question, but what happens when one calls ISession.Delete with a transient entity? I suspect that an exception is thrown, but could not find anything in the documentation.

Answer 1

根据我的经验，不会抛出异常。

Answer 2

It will NOT throw any exception and it will NOT make any db call.

here is the unit test which pass:

    [Test]
    public void TestDeletionOnTransientObject()
    {
        NormalSalesFlowActivity normalSalesFlowActivity =
            Factories.SalesFlowActivityFactory.CreateNormalSalesFlowActivities(null, 
            opt => opt.NoOfEntities(1)).First();

        Assert.That(normalSalesFlowActivity.Id, Is.EqualTo(0));

        Session.Delete(normalSalesFlowActivity);
    }

First parameter of CreateNormalSalesFlowActivies is the NH Session, if it is supplied when entity is attached to Session and by default is stored to db.
