SELECT * FROM train
INNER JOIN station AS s1 ON train.id_station_departure = s1.id
INNER JOIN station AS s2 ON train.id_station_arrive = s2.id
我想获取name1和name2，而不是name和name。我怎样才能做到？
最佳答案
您需要一个列名别名..但在这种情况下您可以使用 select * .. 如果您需要列名别名，则必须使用显式列名
SELECT s1.name as name1, s2.name as name2
FROM train
INNER JOIN station AS s1 ON train.id_station_departure = s1.id
INNER JOIN station AS s2 ON train.id_station_arrive = s2.id
