Code between sessionFactory.openSession() and session.close():


Name and version of the database you are using: MySql

I am very new to hibernate!
How do I create a record in the DB and return it at the same time using the id. For example, if a I have Student with st_id I am trying to do this:


The stundent object that is returned doesn't containt the auto increment id field in the DB.

Hi

You can use session.get(Student.class,strID) and session.load(Student.class,strID). difference between these two is get() is always hit to database and load() is retrive objects from current session cache.

session.load(Student.class,strID);

OK, but will the object returned by load contain the auto incremented id that is generated by the DB ? Let's say I have a table of two fields; id and name only. When I save a new object I don't supply the id it's generated by the DB, How would I return this id? You said load retireves the object fro the cache, but the cached object doen't have the id ! May be I am wrong. Please confirm.
Thank you.

Hi

The id of the student object will fill after trans.commit() . So you can get id by student.getId()
