nhibernate

问题 I have an irritating problem. I've got two objects which are related on two different columns. The relationships are the same (both one-Many) and the structure is as follows BRAND table ID Name [Other stuff] CATEGORY table ID Name BrandID (FK to Brand. Navigation Name Brands) DynamicBrandID (FK to Brand. Navigation Name DynamicBrands [Other stuff] But no matter what I try, I can't get this to work in NHibernate. The HBM files look like they've generated correctly for both objects but no

问题 I have my code working, but I'm getting 2 extra columns in the table/ddl, to represent a Many to Many relationship, ~~but~~ with attributes (scalars) on the relationship. I am using 1.2.0.712 (FluentNHibernate.dll) 3.1.0.4000 (NHibernate.dll) Entities: public partial class Employee { public Employee() { CommonConstructor(); } private void CommonConstructor() { this.MyEmployeeToJobTitleMatchLinks = new List<EmployeeToJobTitleMatchLink>(); } public virtual Guid? EmployeeUUID { get; set; }

问题 I wish to specify a specific command timeout (or LOCK_TIMEOUT) for an SQL and once this time out is reached an exception (or alert) has to be raised in nHibernate. The following is an example pseudo-code what I have written: using (var session = sessionFactory.OpenSession()) { using (var sqlTrans = session.BeginTransaction()) { ICriteria criteria = session.CreateCriteria(typeof(Foo)); criteria.SetTimeout(5); //Here is the specified command timout, eg: property SqlCommand.CommandTimeout Foo

问题 Do you know a good example somewhere for this? What I would like is the following: using(IUnitOfWork uow = UnitOfWork.Start()) { repositoryA.Add(insanceOfA); repositoryB.Add(instanceOfB); uow.Commit(); } But this case is too ideal, because what I also want is multiple UnitOfWorks (per presenter in most cases, and this is not for a web app). In that case, how will repositories know which UnitOfWork to use if I don't give them that explicitly like repository.UnitOfWork = uow; My goal is to have

问题 Please believe me when I say I understand this isn't the "right" way to do this. File this under large-complex-legacy-system questions. We have tables describing OCR'd data of documents. Each document type has its own table. Each table is generated based on the types of fields it expects. So have a schema which looks a bit like this: Table: DocumentTypes Field: Id Field: Prefix Table: DocumentFields Field: Id Field: DocId Field: Name And we would generate tables like: Table: Type1_Data

问题 I have a List that looks like: List<Product> products = new List<Product>(); Product p1 = new Product(1, "Apple", new Description("Red Apple")) Product p2 = new Product(2, "Banana", new Description("Yellow Banana")) products.Add(p1); products.Add(p2); A product looks like this: //Product model public virtual int Id { get; set; } public virtual string Name { get; set; } public virtual Description descriptions { get; set; } //Description model public string description { get; set } Now I want

问题 My Saga message handler (configured as ISagaStartedBy) requests a timeout message for every message received. Debugging through a few messages at a time, I've found the time the first time the handler is fired, the saga ID sent to the timeout manager is different to the one a) persisted in the database and b) the saga ID sent in subsequent messages. The subsequent messages all send the Saga ID from the database. Here's the handler: public void Handle(PaymentRequested message) { int

问题 I've been trying to get this working for a while now with no luck. I want to enable the 2nd level cache to prevent fetching from some lookup tables. I set up my configuration in code cfg = new Configuration(); cfg.Properties[NHibernate.Cfg.Environment.ConnectionProvider] = "NHibernate.Connection.DriverConnectionProvider"; string connectionString = connection.ConnectionString; cfg.Properties[NHibernate.Cfg.Environment.ConnectionString] = connectionString; cfg.Properties[NHibernate.Cfg

问题 This is my code: public IList<VotacaoPlenario> RetornarVotacao(int mesInicio, int anoInicio) { DetachedCriteria criteria = DetachedCriteria.For<VotacaoPlenario>(); if (anoInicio > 0) { criteria.Add(Expression.Eq("YEAR(Data)", anoInicio)); } IList<VotacaoPlenario> votacao = criteria.GetExecutableCriteria(Session).List<VotacaoPlenario>(); return votacao; } } In my table de field Data is Datime i'm need to compare with the variable anoInicio which is int How can i do that? 回答1: The solution here
