NHibernate version:1.2.1.4000

I am trying to query my data base to get an enumerator on all the objects in it. I am simply passing a query in the form of:



This query returns an empty enumerator when I call
(I am not showing all the code)

However if I specifically write the type of the objects I want to take (I have one object type in my data base



query.Enumerable() - now returns an enumerator containing the objects from the data base. In my scenario I do not know the objects type in advance.
I want the query to return an enumerator that enumerates on all the objects.

Am I supposed to enable something in the config or the mapping of person so it will support inheritance in queries?

Thanks

That should work (see http://www.hibernate.org/hib_docs/nhibe ... lymorphism). My guess is that List() would work (loading a large collection in one shot), but that Enumerable() isn't smart enough to set up new cursors when the end of each table in a polymorphic query is reached. So it just balks. If so, this should be fixed or documented.

In the meantime, if you need to use IEnumerable, you'll probably have to do some "thinking for it". I would suggest taking a look at the metadata in the Configuration object. You can find Type objects for all the mapped <class>es (plus a whole lot more, if you want to) there, then iterate over those.
