What is the difference between ISession.SaveOrUpdateCopy() and ISession.Merge()?

由 孤者浪人 提交于 2019-12-05 07:10:24
In NHibernate 3.1, ISession.SaveOrUpdateCopy() has been marked as deprecated. The documentation suggests using Merge() instead. The documentation for each is as follows: SaveOrUpdateCopy(object obj) Copy the state of the given object onto the persistent object with the same identifier. If there is no persistent instance currently associated with the session, it will be loaded. Return the persistent instance. If the given instance is unsaved or does not exist in the database, save it and return it as a newly persistent instance. Otherwise, the given instance does not become associated with the

NHibernate 3 specify sql data type with loquacious syntax

由 南楼画角 提交于 2019-12-04 04:43:02
问题 I'm trying to map an Entity with a string property to a varchar column in NHibernate 3 using the new Loquacious API but I can't figure out how to specify the Type to use. I am able to correctly map the entity with NHibernate 2 and FluentNHibernate. NHibernate 2 w/Fluent Mapping public class EntityMapping : ClassMap<Entity> { public EntityMapping() { Table("EntityTable"); Id(x => x.EntityId).Column("EntityId").GeneratedBy.Identity(); Map(x=>x.Code).Not.Nullable().Column("EntityCode")

What can be used as a NHibernate QueryOver alias?

由 做~自己de王妃 提交于 2019-12-02 12:19:50
问题 I know so far that a local variable or a local property can be used as an alias like so ClassA _aliasA; _session.QueryOver(x => x.ClassA, () => _aliasA); or ClassA AliasA { get; set; } _session.QueryOver(x => x.ClassA, () => AliasA); I want to know what other options are possible. Like, are properties of an external class a valid option? class ClassGenericAliases { ClassA Class { get; set; } } _session.QueryOver(x => x.ClassA, () => ClassGenericAliases.ClassA); Can statics be used as aliases?

NHibernate Current Session Context Problem

由 心不动则不痛 提交于 2019-12-01 01:30:06
问题 I've recently moved from using an ISession directly to a wrapped ISession, Unit-of-Work type pattern. I used to test this using SQL Lite (in-memory). I've got a simple helper class that configures my SessionFactory, created an ISession and then built the schema using SchemaExport and then returned my ISession and the schema lived until I closed the session. I've changed this slightly so that I now configure a SessionFactory, create an ISession, build the schema, and pass the factory to my

Breaking changes with NHibernate 4 upgrade

由 百般思念 提交于 2019-11-30 23:02:15
I can see what's new and fixed in NHibernate 4.0 I would like to know if anyone has had issue with hbm mappings upgrading from NHibernate 3 to 4? I fear that more focus is going on fluent mapping these days. I can test for the more obvious breaking changes but wanted to know if there were any subtle issues that anyone has come across in a production environment that may not be so obvious at first. It looks like a major upgrade and you'd expect there to be the risk of regressions. FYI, I found a new error that is thrown. We use Mapping By Code, and we used to have an entity that had multiple

NHibernate 3.0: TransactionScope and Auto-Flushing

由 ╄→гoц情女王★ 提交于 2019-11-30 15:34:24
问题 In NHibernate 3.0, FlushMode.Auto does not work when running under an ambient transaction only (that is, without starting an NHibernate transaction). Should it? using (TransactionScope scope = new TransactionScope()) { ISession session = sessionFactory.OpenSession(); MappedEntity entity = new MappedEntity() { Name = "Entity", Value = 20 }; session.Save(entity); entity.Value = 30; session.SaveOrUpdate(entity); // This returns one entity, when it should return none var list = session.
