带有Fluent Nhibernate的Oracle 12c Identity列

Question

Recently my application database was updated to use Oracle 12c so in the creation of new tables I have used the new identity feature:

ID NUMBER GENERATED ALWAYS AS IDENTITY,

Within my Fluent mapping I have configured:

Id(x => x.Id).Column("ID").GeneratedBy.Identity();

However when trying to save a new record I'm getting the following error:

NHibernate.Exceptions.GenericADOException: could not insert: [Entity][SQL: INSERT INTO TABLE (ID, AFFECTED_ID, AFFECTED_TYPE, ACTION_TYPE, ACTION_OWNER, ENTITY_ID, ACTION_TIMESTAMP) VALUES (hibernate_sequence.nextval, ?, ?, ?, ?, ?, ?) returning ID into :nhIdOutParam] ---> Oracle.DataAccess.Client.OracleException: ORA-02289: sequence does not exist

I can clearly see that its trying to use a sequence that doesn't exist.

Looking at the current version of Nhibernate the application is using seems to be out of date:

<package id="NHibernate" version="3.3.2.4000" targetFramework="net45" />
Fluent NHibernate 1.3.0.733

Does Fluent Nhibernate support Oracle 12c Identity feature if so how do I get it to work?

Answer 1

I think you should be able to use

Id(x => x.Id).Column("ID").GeneratedBy.SequenceIdentity("Your_Sequence_Name")
