join fetch of a collection + setMaxResults(2) -> 2 departments
SQL contains a row limit: true
SQL> select d1_0.id,e1_0.department_id,e1_0.id,e1_0.city,e1_0.zip,e1_0.level,e1_0.name,e1_0.salary,d1_0.name from (select d1_0.id,d1_0.name from Department d1_0 where exists(select 1 from Employee e1_0 where d1_0.id=e1_0.department_id) order by d1_0.id offset ? rows fetch first ? rows only) d1_0(id,name) join Employee e1_0 on d1_0.id=e1_0.department_id order by d1_0.id
two-step fix -> 2 departments
SQL> select d1_0.id from Department d1_0 order by d1_0.id fetch first ? rows only
SQL> select distinct d1_0.id,e1_0.department_id,e1_0.id,e1_0.city,e1_0.zip,e1_0.level,e1_0.name,e1_0.salary,d1_0.name from Department d1_0 join Employee e1_0 on d1_0.id=e1_0.department_id where d1_0.id in (?,?) order by d1_0.id
