Is the intended behavior of session.save() to always insert a new row into the database, regardless of whether an instance has already been persisted (i.e. the instance already has a generated PK id)?

If I attempt to pass an already persisted instance to session.save() it inserts a new row with identical data, but with a new generated PK id.

I am using Hibernate 2.1.2 with DB2 8.1.

Here's the XDoclet markup on the id column of my class I am persisting:
@hibernate.id column="id" type="integer" generator-class="identity" unsaved-value="null"

And the DDL for my test table is like this:


If this is the intended behavior then it sounds like in this case I should be using saveOrUpdate() instead?

Thanks,
Kevin

Use saveOrUpdate(), of course.
