I have the following tables below. Is it possible to get the routeand the direction depend on the stops order to avoid the result of the opposite stop? So if I have the following stop's name order as Abc, Def, Ghi the result of my query should just consider alle routes which have this stops order Abc, Def, Ghi as I said to prevent the result of the opposite stop that has arrivale time too.
Tables:
CREATE TABLE IF NOT EXISTS routes (
route_id INT(11) NOT NULL AUTO_INCREMENT PRIMARY KEY,
direction VARCHAR(30) NOT NULL,
route INT(11) NOT NULL )
CREATE TABLE IF NOT EXISTS stops
(stop_id INT(11) NOT NULL AUTO_INCREMENT PRIMARY KEY,
name varchar(30) NOT NULL,
lat double(10,6) ,
longi double(10,6)
CREATE TABLE IF NOT EXISTS arrivaltimes(arrivaltimes_id INT(11) NOT NULL AUTO_INCREMENT PRIMARY KEY,
weekday VARCHAR(20) NOT NULL,
route INT(11) NOT NULL,
arrivaltime time NOT NULL,
stop_id INT, FOREIGN KEY fk_stop_id(stop_id) REFERENCES stops(stop_id),
route_id INT, FOREIGN KEY fk_route_id(route_id) REFERENCES routes(route_id)
Query:
SELECT r.route, r.direction FROM routes AS r
JOIN arrivaltimes AS a ON a.route_id = r.route_id
JOIN stops as s on a.stop_id = s.stop_id
WHERE a.weekday = ?
AND arrivaltime between subtime(curtime(), '00:02:00') and addtime(curtime(), '00:02:00')
AND s.name = ?
