Using Sequence Objects When using a database that supports sequence objects (such as Oracle Database), EclipseLink can use a database sequence object to automatically generate identifiers for your persistent objects. Using A Default Sequence EclipseLink can produce a default sequence during schema generation.

In the following example, the @GeneratedValue annotation indicates that the identifier value should be automatically generated; a strategy of SEQUENCE indicates that a database sequence should be used to generate the identifier.
