Hi, Assume I have an entity Foo in the DB.

I am parsing some files and creating new Foo objects and would like to check if the parsed Foo object exists in the DB (using a unique attribute). If it exists already update it otherwise save as a new object.

What is the best approach?

Could I simply set the id and version in the new Foo object?

Or would I be better off loading the Foo object from the DB and copying over the properties from the parsed file?

Thanks.
