JPA: bulk delete queries must use DELETE FROM

[Maia Everett]

org.apache.openjpa.persistence.ArgumentException: "Encountered "User" at character 8, but expected: ["FROM"]." while parsing JPQL "delete User user where user.role = :a1".

The DELETE serialization follows now the JPQL standard :

    @Test
    public void Delete_Clause_Uses_DELETE_FROM() {
        JPQLSerializer serializer = new JPQLSerializer(HQLTemplates.DEFAULT);
        QueryMetadata md = new DefaultQueryMetadata();
        md.addJoin(JoinType.DEFAULT, QEmployee.employee);
        md.addWhere(QEmployee.employee.lastName.isNull());
        serializer.serializeForDelete(md);
        assertEquals("delete from Employee employee\nwhere employee.lastName is null", serializer.toString());
    }
