从两个sql查询中选择常见结果

Question

查询1：

Select route_stop.Route_ID from route_stop,stop where
  route_stop.Stop_ID=stop.Stop_ID AND stop.Stop_Name='Agargaon'

查询2：

Select route_stop.Route_ID from route_stop,stop where
  route_stop.Stop_ID=stop.Stop_ID AND stop.Stop_Name='Mirpur-12'

Answer 1

Select route_stop.Route_ID from route_stop,stop where route_stop.Stop_ID=stop.Stop_ID AND stop.Stop_Name='Agargaon'
Union
Select route_stop.Route_ID from route_stop,stop where route_stop.Stop_ID=stop.Stop_ID AND stop.Stop_Name='Mirpur-12'

要加入同一列，请使用union

Answer 2

按照以下方式使用 -

SELECT route_stop.Route_ID 
FROM route_stop,STOP 
WHERE route_stop.Stop_ID=stop.Stop_ID AND stop.Stop_Name IN ('Agargaon','Mirpur-12')

Answer 3

SELECT Route_ID FROM route_stop JOIN stop ON route_stop.Stop_ID = stop.Stop_ID WHERE stop.Stop_Name =＆＃39; Agargaon＆＃39;或者stop.Stop_Name =＆＃39; Mirpur-12＆＃39;

Answer 4

你可以试试这个，交配：

SELECT
    rs.Route_ID
FROM
    route_stop rs
    INNER JOIN stop s ON s.Stop_ID = rs.Stop_ID
WHERE
    s.Stop_Name IN ('Agargaon', 'Mirpur-12')
GROUP BY
    rs.Route_ID;
