Hi all. I've got an entity Product like this:
[Class(0, Name = "Product", Table = "Products")]
public class Product
{
private readonly ISet<ProductPropertyValue> _productPropertyValues;
private readonly ISet<ProductImage> _productImages;
private readonly ISet<ProductComment> _productComments;

Hi All,
I have finally decided to spend some time looking at using NHibernate for helping TDD my DAL code.
I came across this excellent "foundations of programming" eBook from Karl Seguin and he gave some small examples on using NHibernate, and how it improves the testability of your DAL.
Can anyone here offer any good resources for a...
For me the answer is currently: No, I would use iBatis, because NHibernate is a pain, when the database model and the object model are not in synch. If I don't have full control over the database I end up with a lot of work.
Why do I ask?
Well, first of all: I never used NHibernate. I just know it from the surface. I have read about th...
Hi,
does anybody know how to configure NHibernate properties file to use a connection string already specified in configuration element?

Is there any way to do the following in HQL:

When debugging everything appears good. The insert commits and there is no roll back, no exceptions. I sure hope some can help with this.
Here is my call:
using (ITransaction transaction = _session.BeginTransaction())
{
_session.Save(calc);
transaction.Commit();
}
Real simple mapping:

I have three entities: Customer, Device and LocationTag.
Customers have a list of LocationTags (nothing more than an ID and a Description). They also have a list of Devices.
Devices are tagged with a subset of the Customer's LocationTags, so Devices have a List of LocationTags, too (but only of the Customer's).
If I delete a Locat...
I am considering whether to choose NHibernate.Search or PostgreSQL's embedded full-text search support for my current project.
We are using, as you have already guessed, PostgreSQL RDBMS with NHibernate ORM on the .NET platform. What experience have you on above mentioned full-text engines? Is there any pitfalls I should be aware of?
...
I have come across an issue with NHibernate.Search, where it all of a sudden stopped working, it cannot create files nor read the index-files at all.
NHibernate seems to load it correctly:
2009-01-20 17:37:17,751 [1] DEBUG NHibernate.Impl.SessionFactoryImpl -

The legacy database I've inherited contains the following tables:
Teams (
TeamId INT PRIMARY KEY,
Name VARCHAR(30)
)
Players (
PlayerId INT PRIMARY KEY,
Team VARCHAR(30)
)
The foreign key in the players table refers to the team name, rather than teamId.
I've attempted to map from Team to Players using a bag:
<bag name="Players...
I know that I can Map(x => x.GroupName).WithUniqueConstraint() for a single property.
But how do create a composite unique constraint in fluent nHibernate (where the unique constraint operates on the combination of two columns)?

take a look at this example code:
public class Comment

private Comment()

public Comment(string text, DateTime creationDate, string authorEmail)

Text = text;
CreationDate = creationDate;
AuthorEmail = authorEmail;
}
public virtual string Text { get; private set; }...
I know there are a few people working on getting Nhibernate to support ASP.NET Dynamic Data. Anyone got real life experience of using it?

Please excuse my ignorance on the topic, as I am relatively new to Hibernate / NHibernate, but I have encountered a mapping I can't figure out:
This is what my database table looks like:
<bincontents>
<id>5873715</id>
<title>Video Title</title>
<sortorder>0</sortorder>
<itemid>23079</itemid>
<itemtype>VIDEO</itemtype>

So far the association works fine (the User class loads the appropriate UserRoles instance when present), but when creating a new User and setting its Roles property to a new instance of UserRoles, the UserRoles object is not saved.
Here is my abridged User.hbm.xml:

<hibernate-mapping xmlns="urn:...

I've recently upgraded from NHibernate 1.2 to NHibernate 2.0.1.GA and an issue has occurred attempting to delete an object that references itself.
The mapping file:

I'm having trouble with something that (I think) should be simple, but can't find any clear info.
In the scenario where I have three tables, describing a domain where a person can have more than one job:
Person - has PersonId, Name
Job - has JobId, JobName
PersonJob - has PersonId, JobId, YearsOfEmployment
Note: In my object mode...

I have a one-to-many relationship. I would like to construct this query:
Give me all the parents that have only one child and for this child child.Type=X
Since I 'm learning, please show me the query with the Criteria API and with HQL. Thanks.
And btw, is there any automatic way to know what HQL is identical to a criteria expression ?...
