java - Check date between two other dates spring data jpa

Question

I have this model:

public class Event {
    private String name;
    private Date start;
    private Date end;
}

and repository as

@Repository
public interface EventRepository extends JpaRepository<Event, Long> {
    List<Event> findByEventTypeAccount(Account account);
}

What I want to do is, I will pass one date and need to check that date is between start and end eg(i will pass sept 30 as date and need to find all entries which have sept 30 between their start and end)

Something like findDateisBetweenStartAndEnd(Date date)?

Answer 1

You should take a look the reference documentation. It's well explained.

In your case, I think you cannot use between because you need to pass two parameters

Between - findByStartDateBetween … where x.startDate between ?1 and ?2

In your case take a look to use a combination of LessThan or LessThanEqual with GreaterThan or GreaterThanEqual

• LessThan/LessThanEqual

LessThan - findByEndLessThan … where x.start< ?1

LessThanEqual findByEndLessThanEqual … where x.start <= ?1

• GreaterThan/GreaterThanEqual

GreaterThan - findByStartGreaterThan … where x.end> ?1

GreaterThanEqual - findByStartGreaterThanEqual … where x.end>= ?1

You can use the operator And and Or to combine both.
