Incomplete data while fetching through Named Query JPA2.0 - jpa

Question

I have an entity named ReqestDetail and done association and mapping as below snippet:
#ManyToOne
#JoinColumn(name="STATUS_C")
private StatusCode statusCode;
//bi-directional many-to-one association to RequestAddressDetail
#OneToMany(mappedBy="requestDetail")
private List<RequestAddressDetail> addressDetails;
I have created below Named Query to fetch the details on the basis of address.
TypedQuery<RequestDetail> query = em.createQuery( "SELECT t FROM RequestDetail t" +
" LEFT JOIN t.employeeDetail e " +
" LEFT JOIN t.addressDetails ao " +
" LEFT JOIN t.addressDetails ad " +
" WHERE (e.employeeI IN ( :employeeIds ) ) AND " +
" (ao.postI = :postO AND ao.addressTypeC = :addressTypeO " +
" AND ad.postI = :PostD AND ad.addressTypeC = :addressTypeD )" ,
RequestDetail.class );
However, when I call query.getResultList(), it is only giving me data of RequestDetail Entity but not of the mapping joins I have mentioned in that entity.
Please advise...

Answer 1

why do you think it should give you some joined objects? Your candidate for the query is RequestDetail, so it gives that. If you did a JOIN FETCH then you can fetch other fields, but you haven't done that (so change those LEFT JOIN to LEFT JOIN FETCH) - a JOIN (without FETCH) is simply a convenience way of forming the query.. Alternatively you could set the entity graph to fetch, or set the fetch on the field itself if you wanted those fetching
