nhibernate

问题 I am new to NHibernate and C#, so please be gentle! I have the following two NHibernate entities: Employee { private long _id; private String _name; private String _empNumber; private IList<Address> _addresses; //Properties... } and Address { private long _id; private String _addrLine1; private String _addrLine2; private String _city; private String _country; private String _postalCode; //Properties } and they have a one-to-many relationship from Employee to Address (each employee can have

问题 I've successfully used the CommonLogging layer in NHibernate to log its internal messages using NLog for previous projects which were using hbm.xml files. I'm now switching to fluent mapping, and the NHibernate logs now only contain one line: [Log entry: Warn] 2019-02-01 13:30:42.5537 No mapped documents found in assembly: <assembly name> I also tried to move the nhibernate-logger configuration directive from the App.config file to the code, just after configuring the mapping – and I'm

问题 I'm trying to save (insert) parent object with a collection of child objects, all objects are new. I prefer to manually specify what to save\update and when so I do not use any cascade saves in mappings and flush sessions by myself. So basically I save this object graph like: session.Save(Parent) foreach (var child in Parent.Childs) { session.Save(child); } session.Flush() I expect this code to insert Parent row, then each child row, however NHibernate executes this SQL: INSERT INTO PARENT...

问题 While developing using ASP.net 2.0 (C#) and NHibernate 2.1.0 I am getting the error: System.TypeInitializationException: The type initializer for 'NHibernate.ByteCode.LinFu.ProxyFactory' threw an exception. ---> System.Security.SecurityException: That assembly does not allow partially trusted callers. This error is been thrown only in the production server (a web hosting company) and in my development environment everything is fine. I also ran this code below on the production server to see

问题 I want to use Global transaction manager at my service layer. eg. namespace AssemblyName.Core.Service.Implementation { public class DemoService { public void demo() { save(model); //This is nHibernate transaction SchedulerManager.GetInstance.save(id); //This is related to quartz. } } } What should I use? If I used TransactionScope() then it is giving me error as NHibernateTransaction can't be committed. I have used <object id="transactionManager" type="Spring.Data.NHibernate

问题 I have been experimenting with Entity Framework 4.4, NHibernate 3.3.1.4000 and SQL Server and I have noticed a difference when it comes to fixing up the relationships when you commit your changes, and I was wondering what is the best practice or if I'm doing something wrong. Here's what I tested. I have a classic Parent linked to n Children. I have 2 parents in the database with 20 children each. I load both parents, and I take the first child of the first parent and assign that child the

问题 I am try to convert the following NHibernate query using dyanmic instantiation into an IList<t> rather than an IList. IList<AllName> allNames = (IList<AllName>)Session.CreateQuery( @"select new AllName( name.NameId, name.FirstName, origin.OriginId, origin.Description, name.Sex, name.Description, name.SoundEx ) from Name name join name.Origin origin") .SetFirstResult(skip) .SetMaxResults(pageSize); Running this I get the following error:- Unable to cast object of type 'NHibernate.Impl

问题 I have a paging worked with NHibernate: public IEnumerable<Answer> GetAnswers(int page, int pageSize) { return HibernateTemplate.Execute( session => { var criteria = session.CreateCriteria(typeof(Answer)); return criteria .SetFirstResult((page - 1) * pageSize) .SetMaxResults(pageSize).List<Answer>(); } ); } Now my task is to determine on which page concrete Answer object is placed. How can i do it? Does nhibernate provide some info like index of row in result set? 回答1: NHibernate HQL offers
