Why does NHibernate mapping-by-code ignore my Oracle-cased table name: - oracle

Question

I am using an Oracle Database with NHibernate 3.3.2.4000.
I have a unit test set up to verify that an entity collection can be selected from the table. Here's what it looks like:
[TestFixture]
public class UnitOfWorkIntegrationTests
{
private IUnitOfWork _unitOfWork;
private INHibernateSessionFactory _nHibernateSessionFactory;
private IActiveSessionManager _activeSessionManager;
[SetUp]
public void BeforeEachTest()
{
_nHibernateSessionFactory = new NHibernateSessionFactory();
_activeSessionManager = new ActiveSessionManager();
_unitOfWork = new UnitOfWork(_nHibernateSessionFactory, _activeSessionManager);
}
[Test]
public void ShouldFetchOAuthMemberships()
{
var oauths = _unitOfWork.OAuthMemberships.ToArray();
oauths.ShouldNotBeNull();
}
}
The line that fetches my OAuthMemberships collection is throwing this exception:
could not execute query
[ select oauthmembe0_.id as id13_ from bckgrd_booklet_app.OAuthMembership oauthmembe0_ ]
[SQL: select oauthmembe0_.id as id13_ from bckgrd_booklet_app.OAuthMembership oauthmembe0_]
My OAuthMembership class and mapping are below. As you can see I am defining the table name as "OAUTH_MEMBERSHIP", but the generated SQL includes the camel-cased class name instead. I have no table name conventions defined. Why does NHibernate ignore my Oracle-cased table names?
public class OAuthMembership
{
public virtual int Id { get; set; }
public virtual string Provider { get; set; }
public virtual string ProviderUserId { get; set; }
public virtual UserProfile UserProfile { get; set; }
}
public class OAuthMembershipMap : ClassMapping<OAuthMembership>
{
public void OAuthMembership()
{
Table("OAUTH_MEMBERSHIP");
Id(x => x.Id, m => m.Column("ID"));
Property(x => x.Provider, m => m.Column("PROVIDER"));
Property(x => x.ProviderUserId, m => m.Column("PROVIDER_USER_ID"));
ManyToOne(x => x.UserProfile, m => m.Column("USER_PROFILE_ID"));
}
}
Here's my NHibernateSessionFactory:
public interface INHibernateSessionFactory
{
ISession Create();
}
public class NHibernateSessionFactory : INHibernateSessionFactory
{
private static readonly ILog Log = LogManager.GetLogger(typeof(NHibernateSessionFactory).Name);
private readonly static ISessionFactory SessionFactory;
public static string ConnectionString
{
get
{
return ConfigurationManager.ConnectionStrings["MyConnection"].Return(x => x.ConnectionString,
"Data Source=myServer;User ID=bckgrd_booklet_app;Password=myPass;");
}
}
static NHibernateSessionFactory()
{
try
{
var mapper = new ModelMapper();
mapper.AddMappings(Assembly.GetExecutingAssembly().GetExportedTypes());
HbmMapping domainMapping = mapper.CompileMappingForAllExplicitlyAddedEntities();
var configure = new NHibernate.Cfg.Configuration().Configure();
configure.AddMapping(domainMapping);
configure.BuildMappings();
configure.DataBaseIntegration(x =>
{
x.Driver<OracleClientDriver>();
x.Dialect<Oracle10gDialect>();
x.ConnectionStringName = ConnectionString;
})
.CurrentSessionContext<WebSessionContext>();
SessionFactory = configure.BuildSessionFactory();
}
catch (Exception ex)
{
Log.Error("NHibernateSessionFactory did not initialize correctly.", ex);
throw;
}
}
public ISession Create()
{
Log.Debug("Creating new session.");
return SessionFactory.OpenSession();
}
}
My ActiveSessionManager:
public interface IActiveSessionManager
{
void ClearActiveSession();
NHibernate.ISession GetActiveSession();
void SetActiveSession(NHibernate.ISession session);
}
public class ActiveSessionManager : IActiveSessionManager
{
[ThreadStatic]
private static ISession _current;
public ISession GetActiveSession()
{
return _current;
}
public void SetActiveSession(ISession session)
{
_current = session;
}
public void ClearActiveSession()
{
_current = null;
}
}
Relevant parts of my UnitOfWork definition:
public interface IUnitOfWork
{
//...
IQueryable<OAuthMembership> OAuthMemberships { get; }
IQueryable<T> All<T>();
//...
}
public class UnitOfWork : IUnitOfWork
{
private readonly ISession _session;
//...
public IQueryable<OAuthMembership> OAuthMemberships
{
get { return All<OAuthMembership>(); }
}
public UnitOfWork(
INHibernateSessionFactory sessionFactory,
IActiveSessionManager activeSessionManager)
{
_session = sessionFactory.Create();
activeSessionManager.SetActiveSession(_session);
}
public IQueryable<T> All<T>()
{
return _session.Query<T>();
}
//...
}

I found my error after adding Fluent NHibernate to my project and making the same error there.
My OAuthMembershipMap doesn't have a constructor. I had mistakenly added a void method called OAuthMembership instead, so my table mapping and my Id and Property mappings failed. See the corrected code:
public class OAuthMembershipMap : ClassMapping<OAuthMembership>
{
public OAuthMembershipMap()
{
Table("OAUTH_MEMBERSHIP");
Id(x => x.Id, m => m.Column("ID"));
Property(x => x.Provider, m => m.Column("PROVIDER"));
Property(x => x.ProviderUserId, m => m.Column("PROVIDER_USER_ID"));
ManyToOne(x => x.UserProfile, m => m.Column("USER_PROFILE_ID"));
}
}
