Hello,

I want to declare one of my columns as final. I want that the column is written on an insert but not on an update. The column is a foreign key representing a many-to-one reference in my mapping.
Therefore I found the alter table constraint ON UPDATE NO ACTION.
Is there Hibernate xml mapping support for that? I could not find any attribute on in Hibernate 3.5.6.
As we use the hbm to generate our sql schema we have to declare it there.

What way of preventing column updates does hibernate support?

regards

Use <many-to-one ... update="false" ...> in your hbm.xml. It will not generate the constraint but Hibernate will not include the column in update statements.

Thank you for your reply. Will check this out soon.

edit: Worked fine. Thanks mate.
