Is it possible to push the PK down into an aggregated entity that contains other non-key attributes?

@IdClass and @EmbeddedId allow you to define a PK (or composite key) in an aggregated entity.


But is it possible to map something like:



And yes, I know this is just a bad idea

Thanks!

The JPA spec does not allow this, but some providers may support it.

If using EclipseLink you can use the @PrimaryKey annotation to define your primary key to any desired columns, no matter how they are mapped.

Probably best to mirror the id field in the entity.
 
Don't get me started about those stupid light bulbs.
