Re: [eclipselink-users] CASCADE DELETE at DB-side

Thanks for your help!

Btw, using the @CascadeOnDelete in the trunk version (later in the final 2.2), when I delete my entity, there will be a cascade delete on the DB (because of having the constraint), but will it performing a cascade delete in JPA as well? It would be amazing, if I could use only this annotation, generate DDL, and live happily ever after :)

In the current development stream on EclipseLink (trunk/2.2) Âthere is a
@CascadeOnDelete annotation for declaring the delete cascade constraint.

In the released version of EclipseLink you could,
- use cascade in JPA instead of the constraint
- use cascade in JPA and on the database, EclipseLink will issue the delete,
but should have no affect
- use cascade only in the database, EclipseLink will not issue the SQL, but
object may be left in shared cache (you could invalidate it if you wished)
