I would have used an meaninless ID if I could, my problem is that I'm
making an distributed solution, where the object is saved on the
client and then uploaded to an central server.
In the first scenario when the object is saved on the client all works
fine, but when I want to upload it to the
Hi.
My database schema has quite some references and in order to avoid
loading always a great part of the wohle object graph I would like to
get some of the often used detail data directly in the entity without
denormalizing the schema.
Two concrete examples: In the following mappings the class
Hello all.
I have some questions about a subject that I simply cannot wrap my
head around...
My setup is as follows:
I have three entity types called Shopper, ShoppingList and
ShoppingListItem arranged in an aggregate like this:

I found a way to do it in HQL:
IQuery query = NHibernateHelper.GetCurrentSession()
.CreateQuery(from Square as s where s not in (select
s from Square as s left join s.Items as i where i.ItemId = :ItemId));
query.SetParameter(ItemId, ItemId);
Is this a good solution?
You can do this with Criteria+DetachedCriteria...

I have decided to get the HQL working. Any ideas why this:
IQuery query = NHibernateHelper.GetCurrentSession()
.CreateQuery(from Square as s where s not in (select
s from Square as s left join s.Items as i where i.ItemId = :ItemId )
order by :order)
Thanks Wolfgang.
That worked. I kept thinking that I did not have to supply the c.Id
as the HQL can count the collection with just count(p.Comments).
Much appreciated.

Hi,
We need to use the Sql Server CONTAINSTABLE() function from NHibernate
and the way we have done this in the past is to wrap it in a Table
Value Function (TVF) and then join on this.
Is there a way to use TVFs from NHibernate to map to a type? We will
need to join on the TVF and create
Yes.
A parameter is a value and not a string injection.

But how about the second time you want to save the entity in a new
database, and you want the id's to be the same, or maybe I dont want
to have the same Id, I maybe should have an uniqe id for my receipt
and another one for the db's which in this case could be different,
So when I upload my

Hi Folks,
the title says it all really, we're trying to add NHibernate to a
rather fragile legacy application which still uses those versions, is
it possible to get NHibernate to work with them? If so where could I

Niclas,
In my opinion your application is going down the wrong path. Do you really
want your distributed server piece to be just a database store. When it
receives a message it saves it to the database regardless of what it is
sent? This sounds dangerous to me. Why not build your application a
