Gunnar,
I think you are talking about something different than what I am talking
about.
Say, any updates to this?

Hello All!
I do not mean to beat a dead horse, but the blog posts and articles I have
read on this are 3 or more years old, and refer to NH 2.x.
Why I am asking:
We have a large SQL DB. We are finding that the use of GUIDs as primary
keys and clustered indexes is creating LARGE indexes. Very
Wondering if there is there a way to get the nhibernate dialect for
sqlserver to produce quoted column and table names for sqlserver like:
select this_.[USER] from [MY_TABLE]

Ya that's what I've been doing but that's really a dialect level information
that i would have preferred to have the nHibernate dialect figure out if
possible. Could the dialect not quote all database objects by default?

I've looked around for a bit but I have not found a full list of limitations
of the current Linq provider for nHibernate 3.2. Most of the material found
on the net seems to be applicable to 3.x. How much of an effort would it be
to implement the missing gaps to get it on par with EF4 linq
When I use the same Linq and pass it to Linq to SQL, the generated SQL is:
SELECT COUNT(*) AS [Count], [t1].[STATE] AS [State], [t1].[value] AS
[Assigned]
FROM (
SELECT [t0].[STATE],
(CASE
WHEN [t0].[ASSIGNED_TO] IS NULL THEN @p0
ELSE @p1
END) AS
.ASSIGNED_TO IS NULL THEN
@p1
ELSE
@p2
END AS INT);
This is on a SQL Server 2005 dialect.
My attempt to do the subquery seems to be totally ignored by the linq
provider. Why does nHibernate put the @p01,@p2 in the CASE statement and
what happened to my subquery!
Thanks,
Sam

Sorry I missed a line when I pasted my Linq. It should have read:

Well I was trying to group by counts where there is an assigned user and
where there is not, and hence ended up with the construct. So basically this
type of query is not possible with linq for nHibernate; but is it the case
that no subqueries are allowed in linq?

I am new to nHibernate, so hopefully this is not to much of a newb
question. I am trying to get my first C# .Net3.5 nHibernate Oracle 10g
application running. To get started I have set it to do something
pretty simple, at least I thought.
Here is my hibernate.cfg.xml file:
?xml version=1.0
I have an N+1 issue that happens on a property and can't figure out
what to do.
HasManyToManyFacility(x = x.Facilities)
.Table(UGRXFAC).BatchSize(30)
.ParentKeyColumn(UGRID)
.ChildKeyColumn(FACID)
predicates.
So guys, this is what I'm looking for, but I have no idea how to implement
it. Again thanks for your help and I appreciate all your guidance.
Thanks,
Sam

Yes, you are seeing this correctly, the legacy database has certain

I'm writing a proof-of-concept app for using NHibernate and have a

The code below is a simple method for updating an existing user
object. We intend to utilize web services so it is written with a

What are the best practices for using NHibernate in web services (or
in any n-tier pattern) where you pass your object out of the scope of
the session to the client, have them modify it, then send it back for
persistence?
Simple Example with User object:
* Client calls service to request
/modify individual views because the
view's Model isn't shared by multiple views. It's also easier to see
what a view does because the view model will only contain properties
it needs.
