SummaryThrough simple instance operation, we learned the simple process of nhibernate to SQLite operation, as follows:1. Define a model2. Define how databases work (Database Schema)3. Mapping the model to the database (Mapping the "model to the") (Is this the essence of ORM?) I hope the great God

NHibernate is the current ported version of the most popular Java o/R mapping framework Hibernate , and the current version is 1.0 rc-1. It was born in sf.net. Ibatisnet is another excellent Java o/R mapping framework, and the current version is 1.3. Currently belongs to Apache One of the sub-projects. relative to the NHibernate"o/R",ibatisnet is a " Sql Mapping"of

SummaryNHibernate supports LINQ queries starting from 3.0. Writing LINQ to NHibernate queries is as flexible as writing. NET LINQ code, which makes it easy to implement complex queries. This article uses LINQ to NHibernate to rewrite all previous queries.The code of this article can be downloaded to nhibernate query1. Create IQueryable object, return all customer

In the previous article we mentioned that you can monitor the SQL scripts nhibernate send to the database by overriding the NHibernate Emptyinterceptor interceptor. See a friend today with the LINQPad tool for nhibernate generated SQL statement monitoring, try to feel more intuitive. Of course this is not the main function of LINQPad, but we can use this method

SummaryThis article introduces query over queries introduced in NHibernate 3.2, which is similar to the criteria query. The Iqueryover object is created first, and then the object is queried by invoking the object's API function. This article uses query over to rewrite all previous queries.The code of this article can be downloaded to nhibernate query1. Create Iqueryover object, return all customer informat

The following are information of unknown origin:IntroducedManipulating the database in the same way that the program is run will inevitably result in a series of persisted class instance objects. These objects may have just been created and ready to be stored, or they may be queried from the database, in order to differentiate between these objects, depending on the state of the object and the current session, we can divide the object into three kinds:Instantaneous object: Object just establishe

Learning and using nhibernate has been a long time, has been trying to write something and everyone to learn to use NHibernate. There are also many articles in the blog park that are written about NHibernate's entry. Among them: Li Yongjing Blog http://www.cnblogs.com/lyj/tag/NHibernate/content is the most abundant. And in Mfullyaware's blog to learn a lot of thi

This can easily extend to the nhibernate cache. We use the NHibernate caching mechanism flexibly in the project.

One-to-multiple nhing of Nhibernate and nhing of Nhibernate In nhib, The ing file corresponds to the relationship in the database table. All Nhibernate instances also have one-to-one ing, one-to-many ing, and many-to-many ing. First, let's look at one-to-many ing. one-to-many ing means that the relationship between two tables in the database is one-to-many. For e

Use NHibernate to insert nearly 100,000 records into the database, as in the following example:ISession session = session. BeginTransaction (); for int i=0; i100000; i++ ) { new Customer (...); Session. Save (customer);} Tx.commit (); session. Close ();This will throw OutOfMemoryException and terminate at about 50 000 records. This is because nhibernate caches all newly inserted customer instances i
