All Implemented Interfaces
org.hibernate.id.PostInsertIdentifierGenerator, org.hibernate.id.IdentifierGenerator
Imports
org.hibernate.id.insert.InsertGeneratedIdentifierDelegate, .AbstractReturningDelegate, .IdentifierGeneratingInsert, org.hibernate.dialect.Dialect, org.hibernate.HibernateException, .MappingException, org.hibernate.sql.Insert, org.hibernate.type.Type, org.hibernate.engine.SessionImplementor, org.slf4j.Logger, .LoggerFactory, java.io.Serializable, java.sql.PreparedStatement, .SQLException, java.util.Properties
A generator which combines sequence generation with immediate retrieval through JDBC3 getGeneratedKeys. 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.
