Very interesting...thanks for the link.
If you just read data with a Get, do you still need to call
tx.Commit() at the end?

Hi! Does NHibernate provide streaming support? If not, are there other
ORMs than has this feature?
What I mean by streaming is that the users can see the rows/objects
being loaded one-by-one/partially (Think of SQL Management Studio when
the query result is thousands of record). I can't implement
Hi guys.
I thinking about converting my data access layer to NHibernate. I have

inserting and updating. I select using SQL from some views too. It's

Every record in my database has
ID - obvious
IV - version of that
Its not clear to me how this would work (efficiently) in practice.
Having even ONE connected client (never mind multiple clients)
performing an unbounded query that could return 10K records from 250M
in a single query seems a) a database interaction design anti-pattern
and b) a tremendous
Depends on the setting of FlushMode re: whether you must do it
explicitly or not, but in general, yes, you need to commit the tx at
the end of the tx block *somehow* b/c the whole point of that piece
referenced above is that you don't necessarily know whether your Get()
has in fact involved a

is it possible to lazyload a component ?
I have set lazy=true in the mappings for the component, and it is not

yes, you should still call commit (rollback) because the session was
opened (began) you will want to explicitly end the transaction (commit/
rollback).
the common web usage scenario is
1. begin request open session
2. use a transaction filter on Controller Actions to manage the

i read my entity's List T with Session A. If i modify a couple of
them and call SaveOrUpdate from Session B i can see that all my
entity's are updatetd to the Database.
Is there a clean way to do dirty checking with detached objects witch
i can use for all my entiy's.
Thanks

I don't understand your question.

see how having SP's or no changes anything.
If your situation is that you have everything done via SP, why you want use
a framework based in ORM ?

there might be a better way that i don't know of... but what i know is that

you can then watch the list of methods you can override

NH isn't required for DDD. In your scenario i think integrating NH

abstract the scripts with a Repository/DAO and you're set.

Hi Peter,
You can activate select-before-update=true in your class mapping or use
session.Merge(entity) instead of session.SaveOrUpdate(enity). Then only
modified entities will be updated. You can also activate
dynamic-update=true in your class mapping so only modified columns will be
updated.
