Hi...

I am sathish.I have the problem while updating an object using
session.update(ob) in the different session.

I save an item which has id,name,color and address properties. i save this item using session.save(item). It stored in the table with id=1

In different session i created an item and set the id=1 and set the name.
Then i used session.update(item). It is updated the new name in the table but other propereties updates as null values. How can i restrict that only avialble values are updated so that other values are safe.

Can we do the updation without loading the object.


Thank you ,

You can't. Either load the object, or set all properties correctly. How should Hibernate know that you don't want a property to be null.
