JPQL ManyToMany select

Question

I have a Many To Many relationship between two entities called: Car and Dealership.

In native MySQL I have:

car (id and other values)
dealership (id          


        

Answer 1

select car from Car car 
inner join car.dealerships dealership
where dealership in :dealerships

The parameter must be a collection of Dealership instances.

If you want to use a collection of dealership IDs, use

select car from Car car 
inner join car.dealerships dealership
where dealership.id in :dealershipIds

Remamber that JPQL always use entities, mapped attributes and associations. Never table and column names.
