Invalid IN query/statement with to much '?' parameter - jpa

Question

There are limitations for some databases how much parameter '?' can exist in an IN statement e.g. in MS SQL the limit is 1000.
However, when I create an IN query with a Pageable, this limitation is not considered. For example, if I search for 1200 names, it will be 1200 '?' used in the IN statement. This crashes under MS SQL with the following error:
Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: The incoming request has too many parameters. The server supports a maximum of 1200 parameters. Reduce the number of parameters and resend the request.
Repo:
#Repository
public interface CourseRepository extends JpaRepository<Course, UUID> {
Page<Course> findAllByNameIn(Collection<String> names, Pageable pageable);
}
Test class:
#SpringBootTest
public class SqlQueryTest {
#Autowired
private CourseRepository courseRepository;
#Test
public void testInQuery() {
final List<String> names = new ArrayList<>();
IntStream.range(0, 1200).forEach(count -> {
final Course course = new Course();
final String name = RandomStringUtils.randomAlphabetic(10);
names.add(name);
course.setName(name);
courseRepository.save(course);
});
courseRepository.findAllByNameIn(names, Pageable.ofSize(500));
}
}
Statement looks like
select
course0_.id as id1_0_,
course0_.name as name2_0_
from
course course0_
where
course0_.name in (
? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ? , ....
I've also tried EclipseLink Query hints batch_size and batch_type IN. However, without success. See https://www.eclipse.org/eclipselink/documentation/2.5/jpa/extensions/q_batch_size.htm
So my question is that a bug if an invalid statement is executed? Do I have to take care of it myself and split up the selects.
When I load a relationship in an IN statement, the batch size is works and several selects are executed with IN
Is it possible to execute individual selects (e.g. findByName) and execute them in batch?
