I am attempting to merge a detached entity object with a pre-persisted entity. How do I ignore certain columns to merge. I have a create_sysdate column that I do not set on my detached object. So when I attempt to merge the entity I receive a create_sysdate column can not be null. Is there a simple way around this? Or do I need to run a query to obtain the create_sysdate and set it on the detached object. I hope there is an easier way.

Sorry everyone I answered my own question. In the column annotation i just simple add::

updatable = false

Well done!

Thanks for posting back with the answer. It will help people who query the same problem.
