问题 I am in a stage of mapping my CSharp classes into database tables. I have decided to use NHibernate as my ORM tool after comparing with other tools. I have never done a real project with NHibernate before and now am considering alternatives for the mapping, ActiveRecord: according to the project's web site, using ActiveRecord can boost productivity dramatically. However, I do not like the idea of adding attributes to my CSharp classes. After all, my class should NOT have any knowledge of

Reference parent table alias in Fluent NHibernate ClassMap Formula?

由 对着背影说爱祢 提交于 2019-12-07 18:00:34
Is it possible to reference or rename an entity's table alias in a Fluent NHibernate Formula? I can usually use "this_" but that unfortunately does not seem to be consistent based on the number of other aliases NHibernate generates. this.Map(x => x.IsLocked).Formula("CASE WHEN (SELECT COUNT(*) FROM dbo.Child c WHERE c.InboundDate >= BeginDate AND c.InboundDate < EndDate) > 0 THEN 1 ELSE 0 END"); This gets me by but I run into trouble when I need to match of identically named fields, (like "ID.") this.Map(x => x.IsLocked).Formula("CASE WHEN (SELECT COUNT(*) FROM dbo.Child c WHERE c.ID = ID) > 0

Fluent NHibernate: override derived classes not in the base class auto-mapping

由 杀马特。学长 韩版系。学妹 提交于 2019-12-07 16:41:10
问题 The story: I had class User and class Organization: User. I did not use any mappings for these classes, let FNH do mapping automatically. Then, I added public class OrganizationMap : IAutoMappingOverride<Organization> { public void Override(AutoMap<Organization> mapping) { } } Notice there're no overrides. So I did not expect any changes in FNH behavior. But I got this (during schema export actually): NHibernate.MappingException: (XmlDocument)(2,4): XML validation error: The element 'class'

Handling a one-to-many relationship with value types in Fluent NHibernate

由 谁说我不能喝 提交于 2019-12-07 13:21:52
问题 I'm working on migrating an application to NHibernate, and I'm using Fluent NHibernate. I'm running into an issue mapping a collection of value types to an aggregate root. I have a PhoneNumber value type that has a few properties — Number , NumberType , and Description . There are a number of objects in my domain that have collections of phone numbers. In the database (SQL 2008), these values are held in different tables. So I might have Customers and CustomerPhoneNumbers as well as Vendors

Fluent NHibernate exception moving objects between collections

问题 When moving an object from one collection to another and when cascade is set to all-delete-orphan, I get the following exception: deleted object would be re-saved by cascade (remove deleted object from associations) I thought that nhibernate would not delete an object when it is referenced in another collection when you use all-delete-orphan. Can anyone confirm that, when you have objects like Folders which contain Folders or Files and you move a File from one Folder to another, you should
