lazy-loading

I faced the problem that one-to-one lazy loading doesn't work in hibernate. I've already solved it , but still don't properly understand what happens. My code ( lazy loading doesn't work here , when I pull Person - Address is also fetched): @Entity public class Person{ @Id @SequenceGenerator(name = "person_sequence", sequenceName = "sq_person") @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "person_sequence") @Column(name = "id") private long personID; @OneToOne(mappedBy="person", cascade=CascadeType.ALL, fetch = FetchType.LAZY) private Adress address; //.. getters, setters }

This may be a really elementry question but whats a nice way to include multiple children entities when writing a query that spans THREE levels (or more)? i.e. I have 4 tables: Company , Employee , Employee_Car and Employee_Country Company has a 1:m relationship with Employee. Employee has a 1:m relationship with both Employee_Car and Employee_Country. If i want to write a query that returns the data from all 4 the tables, I am currently writing: Company company = context.Companies .Include("Employee.Employee_Car") .Include("Employee.Employee_Country") .FirstOrDefault(c => c.Id == companyID);
