org.hibernate.id
Class SequenceIdentityGenerator  

java.lang.Object
  org.hibernate.id.SequenceGenerator
      org.hibernate.id.SequenceIdentityGenerator

All Implemented Interfaces:

Configurable, IdentifierGenerator, PersistentIdentifierGenerator, PostInsertIdentifierGenerator

---

public class SequenceIdentityGenerator

extends SequenceGenerator

implements PostInsertIdentifierGenerator

A generator which combines sequence generation with immediate retrieval through JDBC3 getGeneratedKeys 55 . In this respect it works much like ANSI-SQL IDENTITY generation.

This generator only known to work with newer Oracle drivers compiled for JDK 1.4 (JDBC3).

Note: Due to a bug in Oracle drivers, sql comments on these insert statements are completely disabled.
