orm nhibernate

The basic feature of NHibernate is to accomplish the mapping of object-oriented programming language to relational database, and to use the Persisted object Po (persistent object) to complete the persistence operation in NHibernate. The operation of the PO must be in Session management to synchronize to the database, but here the session does not mean httpsession, it can be understood that the connnection,s

Save the updated object Conclusion Operational Data OverviewWhat we often call a unit of work, typically performing 1 or more operations, is either committed or discarded/rolled back for these operations. Thinking about using LINQ to SQL, everything is operating in memory, and only the Datacontext.submitchanges () method is called to commit the changed

Using server controls such as ObjectDataSource and GridView can indeed achieve very oop (however, I prefer to bind with Repeater, which is a little troublesome, and this is very fast) However, if dependency injection is required for applications in a multi-layer framework, ObjectDataSource needs to be bound to the interface. ObjectDataSource only supports classes and cannot instantiate interfaces. This will lead to the dependency of the multi-layer structure. Google found it for half a day. You

During routine development, NHibernate transactions are often used. Because NHibernate does not support nested transaction operations, ASP. net mvc usually uses a transaction to encapsulate database operations in a request. The following are some of the most beautiful statements I think. View sourceprint? 01 using System. Web. Mvc; 02 using nhib.pdf; 03 04 namespace WebMVC. Filters 05 { 06 public class Tran

Use the HQL in NHibernate to query the data.Code:1 /// 2 /// Find Events 3 /// 4 Private void Btn_select_click (object sender, EventArgs e)5 { 6 7 }1.

[Subject to nhibernate-PreAlpha-Build-2] We can see that session and sessionfactory are the core parts of Nhibernate. Sessionfactory maintains connections to the persistent mechanism (database) and manages them. It also saves the ing information of all persistent objects. Sessionfactory is created by configuration. buildsessionfactory. This object generally uses the singleton mode. Session is used
