Question

Struggling to write the following query using JPA.

Oracle Query:

Select * from table1 s
where exists (Select 1 from table2 p
              INNER JOIN tab         


        

Answer 1

You can do it much simpler using JPA Queries or HQL instead of Criteria builders:

SELECT e1 from Entity1 as e1 
where exists
(select e2 from Entity2 as e2 join e2.e3 as ent3
where ent3.id=e1.id and e2.name='Test')
