PHP MYSQL 根据两个匹配的行列检索数据

Question

I have a table where i need to check or compare two rows two column are equal then only i need to retrieve data

my table structure is

id | route_id | stop_id | bus_id | bus_time | trip | direction

if i execute following query

select routes.route_name,stops.stop_name,buses.bus_name,bus_timings.bus_time,bus_timings.trip,bus_timings.bus_direction from `bus_timings` 
inner join `stop_orders` on `stop_orders`.`id` = `bus_timings`.`stop_order_id` 
inner join `routes` on `stop_orders`.`route_id` = `routes`.`id` 
inner join `stops` on `stop_orders`.`stop_id` = `stops`.`id` 
inner join `buses` on `buses`.`id` = `bus_timings`.`bus_id` 
where `stops`.`stop_name` in ("sydney","melborne")

output

1 | route_1  | Sydney | bus_1 | 07:05 :00 | 1 |1
2 | route_1 | Melbourne| bus_2 | 07:35:00 |1 |1

but in existing query even if bus is not traveling between Sydney also i will get Melbourne result . I need to get only buses name which falls or travel between Sydney to Melbourne

Answer 1

simple way to do that , without much fuzz , and as u mentioned using PHP, so use only one where clause in the query statement and than filter the data using php, for example , after you retrieve the buses between Sydney and Melbourne, make a foreach loop and use if condition with selected times.

another way us that if you like using arrays match the times in each record using any array search function and get the keys out to another array. the result array will contain the filtered data with buses between cities and between selected time.
