/**
|
|
* Shared by the HQL chapter (15) and the Criteria API chapter (16) — both posts use the
|
|
* same Employee/Department pair in their examples, so one real mapping backs both rather than
|
|
* two near-duplicates.
|
|
*
|
|
* <p>Named {@code QueryDept} (entity name, via {@code @Entity(name = ...)}), not {@code
|
|
* Department}, because chapter 06's {@code naturalid.Department} already claims that entity
|
|
* name in this same persistence unit -- Hibernate requires distinct entity names project-wide,
|
|
* not just distinct class names.
