Question

I have next code

getEntityManager().persist(country.getCity().getClinic().getPatient());

and see next sql in log

Hibernate: 
select
    next value for patient_seq 
from
    dual_patient_seq
Hibernate: 
    select
        next value for clinic_seq 
    from
        dual_lclinic_seq
Hibernate: 
    select
        next value for city_seq 
    from
        dual_city_seq

But sequence for ‘country’ isn’t generated. All XML are allright. Whan is the problem?

Answer 1

Thx, Thomas! Problem was in ‘cascade’. I change City.hbm.xml from

  <set name="countrysPersistent" lazy="true" inverse="true" >
   <key column="country" />
         <one-to-many class="Country" />
      </set>

to

<set name="countrysPersistent" lazy="true" inverse="true"  cascade="all">
    <key column="country" />
         <one-to-many class="Country" />
      </set>

and it was helpful!
