    <p>I am using ConfORM Nhibernate in one of my MVC project. And had problem with One to Many Mappings. </p> <pre><code> IEnumerable&lt;Type&gt; domainEntities = this.GetDomainEntities(); var relationalMapper = new ObjectRelationalMapper(); relationalMapper.TablePerConcreteClass(domainEntities); relationalMapper.Patterns.PoidStrategies.Add(new NativePoidPattern()); relationalMapper.Cascade&lt;Category, Product&gt;(Cascade.All); relationalMapper.ManyToMany&lt;Category, Product&gt;(); relationalMapper.Cascade&lt;Order, Product&gt;(Cascade.Persist); var mapper = new Mapper(relationalMapper); var englishInflector = new EnglishInflector(); mapper.PatternsAppliers.Merge(new ClassPluralizedTableApplier(englishInflector)); mapper.PatternsAppliers.Merge(new OneToManyKeyColumnApplier(relationalMapper)); ..... HbmMapping mapping = mapper.CompileMappingFor(domainEntities); </code></pre> <p>And classes Order and User: One User had many Orders.</p> <pre><code> public class Order : BaseEntity { public Order(User user) { if (user == null) { throw new ArgumentNullException("user"); } this.User = user; } protected Order() { } public virtual User User { get; protected set; } } </code></pre> <p>And Users:</p> <pre><code> public class User : BaseEntity { public User() { this.Orders = new HashedSet&lt;Order&gt;(); } public virtual string FirstName { get; set; } public virtual ISet&lt;Order&gt; Orders { get; protected set; } } </code></pre> <p>I expect relations like this: Orders.UserId -> User.Id in the DB. But when the Nhibernate had genereted DB we had this problem (See image):</p> <p><img src="https://i.stack.imgur.com/PK9I9.jpg" alt="table structure"></p> <p>UPS. Double reference User and UserId suddenly uppeared. And when we removed [user] Nhivernate can`t do inner join this tables. It sad that double time: Invalid column name 'User'. Invalid column name 'User'.</p> <p>I think there is some problems with setuping ConfORM. If I remove mapper.PatternsAppliers.Merge(new OneToManyKeyColumnApplier(relationalMapper)); ConfORM generete just [User] reference key.</p> <p>Anyone know what the problem is here? Thanks in Advance.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
