QUESTION
I have two tables:
- Car_company which has the attributes of: C_id (primary key), C_name
- Car_model which has the attributes of: Com_id (referenced to C_id of Car_company), Model_year Warranty
I wish to access both of these tables individually and also I would like to perform a join operation on them and display all of the car_models along with their car_company name. I tried using both JPQL and native query but nothing worked. I also made sure to use the OneToMany and ManyToOne associations but I ended up getting infinite nesting,i.e, the models have car_company as field, this inturn has car_models as a list, and this keeps going. Please help me with entity classes and DAOs.

Answered 2021-Jun-15 at 16:12You can get a List of CarModel for each car company in the CarCompany entity through the oneToMany annotation like this:
