First off, I'm new to LLBLGen Pro.

Is there a way to gracefully add optimistic concurrency to all entities where saving the entity only updates the fields which have changed?

Thanks!

Please consult the section of the manual about Concurrency control: using the generated code - adapter - using the entity classes - concurrency control.

By default entity fields are marked as dirty when their value changes. When an entity is saved only these dirty fields are saved to the database.
