Question

Is there any way we can use Left join on non related Tables or Entity using their ID only? in Criteria Builder

class A (
   val id: UUID
   val message: String
)

class B (
  val id: UUID
  val a_id: UUID,
  val type: Boolean
)

is there any thing that can build like this using criteria builder? or any suggestion?

Select a, b from A a left join B b on a.a_id = b.id

Here is a quote from the book Java Persistence with Hibernate :

JPA and Hibernate don't support arbitrary outer joins without a mapped entity association or collection.

For your requirement, you should fall back to native SQL.
