            query="SELECT c FROM Customer c WHERE c.name LIKE :custName"
    )
 
 The following is an example of the use of a named query:
    @PersistenceContext
    public EntityManager em;
    ...
    customers = em.createNamedQuery("findAllCustomersWithName")
            .setParameter("custName", "Smith")
            .getResultList();
