How to fix data sampling by time?

Question

MySQL

I have two fields in a table of type timestamp : date_departure and date_arrival .

And there is a corresponding QHL (I think that you can understand it in SQL) query for selecting data.

If my user entered the date_departure input field and did not enter date_arrival, then I call the first DAO functionality. If the user entered both fields - the second one.

I have:

1st

public List<Schedule> getByStationsViaDate(Schedule schedule) {
        return sessionFactory.getCurrentSession()
                .createQuery("from Schedule where " +
                        "stationArrival = :stationArrival and " +
                        "stationDeparture = :stationDeparture and " +
                        "dateDeparture > :dateDeparture " +
                        "order by dateDeparture desc ")
                .setParameter("stationArrival", schedule.getStationArrival())
                .setParameter("stationDeparture", schedule.getStationDeparture())
                .setParameter("dateDeparture", schedule.getDateDeparture())
                .getResultList();
    }

2nd:

public List<Schedule> getByStationsViaDates(Schedule schedule) {
        return sessionFactory.getCurrentSession()
                .createQuery("from Schedule where " +
                        "stationArrival = :stationArrival and " +
                        "stationDeparture = :stationDeparture and " +
                        "dateDeparture > :dateDeparture and " +
                        "dateArrival < :dateArrival " +
                        "order by dateDeparture desc ")
                .setParameter("stationArrival", schedule.getStationArrival())
                .setParameter("stationDeparture", schedule.getStationDeparture())
                .setParameter("dateDeparture", schedule.getDateDeparture())
                .setParameter("dateArrival", schedule.getDateArrival())
                .getResultList();
    }

How can I fix the query so that in the first case the data is pulled by the departure date?
