Hi.
I apologize if that's a stupid question, but
I have an application with entity classes that contain a synthetic key for hibernate (a Long), and a
natural keys (which is used in the equals() implementation).
I have have a scenario (which I guess is not uncommon), where I have a set of objects, for which I know
the natural keys values, but I don't know if there is a matching row in the database. I would like to save
the entries that don't have one, and update the ones that do. I guess Session.saveOrUpdate() would
not be useful in this situation, since I don't know the synthetic key values of the object (if it's saved), only the natural one.
I could use for any of those objects an hql query that tries to retrieve it by it's natural keys values,
but this feels a little inefficient and overly complex, and I can just try to save() it and handle an exception
from JDBC, if the matching row is already in the database (assuming I assign a unique key to the class's natural keys)
is there a better way that I am missing here ?
Thanks.
