“ERROR: ORA-00917: missing comma” when using Hibernate with an existing sequence in oracle

Question

I used the annotation suggestion from this article:

How to use existing Oracle sequence to generate id in hibernate?

@GenericGenerator(name = "announcementGenerator", strategy = "sequence-identity", 
                    parameters = @org.hibernate.annotations.Parameter(name = "sequence", value = "ANNOUNCEMENT_ID_SEQ"))
@Id
@GeneratedValue(generator = "announcementGenerator")
@Column(name="ANNOUNCEMENT_ID")

But I still get the error in the title. The generated sql from hibernate seems to include

next value for ANNOUNCEMENT_ID_SEQ

Instead of the traditional

ANNOUNCEMENT_ID_SEQ.nextval

I've also used the suggestion in this article: ORA-00917: missing comma error while using custom oracle sequence in hiberanate

And it put a null in the place of the primary key... which makes sense with the annotation given in that article.

Am I missing something? Any assistance would be appreciated. Thanks in advance!

Answer 1

From Hibernate doc about sequence-identity

This strategy is only supported on Oracle 10g drivers targeted for JDK 1.4.

If you aren't using 10g set strategy = "sequence" or "native" can solve the problem.

Else use

@GeneratedValue(strategy=GenerationType.AUTO, generator="announcementGenerator")
@SequenceGenerator(name="announcementGenerator", sequenceName="ANNOUNCEMENT_ID_SEQ")

Hope can help.
