 Post subject: How to use merge but ignore specific columns to merge data

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.

updatable = false
