why simple select query returns List but join query return List<Object> in jpa

Question

I am using play framework with jpa. I have a model Jobads with 2 functions to findall() findByLocation()

My Model

  public class Job         


        

Answer 1

It's happening because that's how HQL queries without a select clause work. Note that these are not valid JPQL queries. JPQL makes the select clause mandatory, and using a select clause would allow you to specify what you want the query to return:

select j from Jobads j join j.city c WHERE c.name LIKE :location
