hi *!
i did some experimenting with the native id generator in oracle (OracleDialect). my test was simply adding a new object with a auto-generated id and a name.

here the mapping:


so when i added the object with Session.saveOrUpdate, nothing happened (no data in database). after turning on sql output, i recognized, that a sequence HIBERNATE_SEQUENCE was selected, and because it wasn't found (i didn't create it), update statements were performed (which did nothing).

my expectation would be that some exception will be thrown, if this sequence isn't found or if update statements return zero modified lines.

You are mistaken,

could you please explain that more detailed?

Well, no, its you who are missing the detail!

certainly Hibernate throws an exception if the sequence is missing.

I think you should turn on Hibernate debug logging and see whats really happening

hm. ok. maybe spring hides this exception (i use the spring hibernate template). i'll look for that.

hm. now i see the exception. i swear, yesterday, there was no exception. hm. in that case, please excuse my disturbance.
