Use @DeleteAll
to indicate that when an relationship is deleted, EclipseLink should use a delete all query. This typically happens if the relationship is PrivateOwned
and its owner is deleted. In that case, the members of the relationship will be deleted without reading them in.
Annotation Elements
There are no elements for this annotation.
Usage
WARNING: Use this annotation with caution. EclipseLink will not validate whether the target entity is mapped in such a way as to allow the delete all to work. |
