Example 10 with CopyGroup

use of org.eclipse.persistence.sessions.CopyGroup in project eclipselink by eclipse-ee4j.

the class SimpleSerializeFetchGroupTests method copyGroupMerge.

public void copyGroupMerge() {
    // Search for an Employee with an Address and Phone Numbers
    EntityManager em = createEntityManager();
    try {
        beginTransaction(em);
        TypedQuery<Employee> query = em.createQuery("SELECT e FROM Employee e WHERE e.id IN (SELECT MIN(ee.id) FROM Employee ee)", Employee.class);
        Employee emp = query.getSingleResult();
