如何在 JPQL 中正确执行 LIKE 和 CASE 子句
How to properly execute LIKE and CASE clause in JPQL
我想执行一个在 sql 中有效的查询，但是当我尝试使用 @Query 注释 运行 它时，程序就死了，我正在尝试将一个字符串与一个substring，我不知道该怎么做。我已经尝试了很长时间来弄清楚如何解决这些问题。
package stpt.Repository;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.query.Param;
import stpt.entities.StopTimes;
import java.util.Date;
import java.util.List;
public interface StopTimesRepository extends JpaRepository<StopTimes,String> {
@Query("SELECT arrivalTime FROM StopTimes st WHERE tripId IN (:id)")
List<String> findBySpecificTime(@Param("id") String id);
@Query("SELECT distinct st.arrivalTime \n" +
"FROM StopTimes st, Trips t, Routes r, Stops s \n" +
"WHERE r.routeShortName IN (:short_name)\n" +
"AND t.tripHeadsign IN (:heading)\n" +
"AND st.tripId=t.tripId\n" +
"AND t.routeId=r.routeId \n" +
"AND s.stopId=st.stopId\n" +
"AND CASE WHEN dayname(current_date())='saturday' OR dayname(current_date())='sunday' THEN t.serviceId like '%-sd' else t.serviceId like '%-lv' END\n" +
"AND CASE HOUR(current_time())=11 THEN st.arrivalTime LIKE '23%' else st.arrivalTime LIKE '23%' END\n" +
"AND s.stopName IN (:stop)")
List<String> findByArrivalTime(@Param("short_name") String short_name, @Param("heading") String heading, @Param("stop") String stop);
}
st<String> findByArrivalTime(@Param("short_name") String short_name, @Param("heading") String heading, @Param("stop") String stop);
}
