Hello,

I have a question, i have a entity :
Person.

String Name
String FirstName.

I load object in session, I change only the Name with the setter and when the Session is flush the SQL order is :

Update Person set name = "", firstName ="" where id = "".

The firstName is changed too !

It's possible ta have a sql query like this (maybe a configuration of hibernate is needed ? ):

Update Person set name = "" where id = "".

Thanks

This can be reached by Dynamic SQL generation (Java Persistence with Hibernate, Chapter 4.3.1).

Code:

<class name="Person" dynamic-update="true>
...
</class>

alternatively with annotations:
