Question

我试图在hibernate中运行下面提到的过程，但我不知道该怎么做？

DELIMITER $$
CREATE PROCEDURE LoadData(
aircraft_id1 bigint, provider_fl_id varchar(32), city1 varchar(32), time1 timestamp, fare decimal(10,4), 
city2 varchar(32), time2 timestamp)
        BEGIN
                DECLARE flId bigint default 0;
                DECLARE rId int default 0;
                DECLARE r_id bigint default 0;
                DECLARE seat_no int default 0;
                SET rId=-1;
                SET flId=-1;
                SET r_id=-1;
                SET seat_no=-1;
                SELECT flight_id into flId from flight_schedule where
aircraft_id=aircraft_id1 and
                ((from_datetime > time1 and from_datetime < time2) or (to_datetime >
time1 and to_datetime < time2)) limit 1;
                if flId < 0 THEN
                    Select count(*) into rId from route where source=city1 and destination=city2;
                        if rId < 1 THEN
                            Insert into route(source,destination) values(city1,city2);
                        end if;                     
                        Select route_id into r_id from route where source=city1 and destination=city2;
                        Select seats into seat_no from aircraft where aircraft_id=aircraft_id1;
                        Insert into flight_schedule(route_id, aircraft_id, provider_flight_id,
                            from_datetime, to_datetime, seats, fare) values(r_id,
                                aircraft_id1, provider_fl_id, time1, time2, seat_no ,fare);
                Select "Success" as Result;
                else Select "Failure" as Reuslt;
                end if;
        END $$
DELIMITER ;

我正在使用下面的代码，但它不起作用。

HibernateUtil
                            .getSession()
                            .createSQLQuery(
                                    "CALL (:aircraftId, :providerFlightId, :city1,:time1,:fare,:city2,:time2)")
                            .addEntity(String.class)
                            .setParameter("aircraftId", row[0])
                            .setParameter("providerFlightId", row[1])
                            .setParameter("city1", row[2])
                            .setParameter("time1", row[3])
                            .setParameter("fare", row[4])
                            .setParameter("city2", row[5])
                            .setParameter("time2", row[6]);

我想我也必须调用addEntity（），但我不知道哪个类可以工作？任何链接，帮助或参考都将是值得注意的。谢谢。

我使用createSqlQuery方法解决了我的问题＆amp;简单地运行它而不使用addEntity或setParameter。此外，mysql终端显示的结果应该是结果集的列表类型。如果您想要更多澄清，请告诉我。谢谢。
