I have two tables as below :
vehicles :
vehicle_id number_plate
1 B 101 RA
2 B 501 JU
3 B 401 JA
4 B 201 RU
team :
team_id team_name available_vehicles
1 A-001 1,2
2 A-002 NULL
3 A-003 4
I want to get value where the position of vehicle in the team table, my desired output would look like this:
vehicle_id ║ number_plate ║ team_name
1 ║ B 101 RA ║ A-001
2 ║ B 501 JU ║ A-001
3 ║ B 401 JA ║ NULL
4 ║ B 201 RU ║ A-003
You can use find_in_set-function, but that would be quite inefficient for larger datasets.
select v.vehicle_id, v.number_plate, t.team_name
from vehicles v
join team t on find_in_set(v.vehicle_id, t.available_vehicles);
You should consider creating proper database structure with a separate table for
create table team_vehicles (
team_id int,
vehicle_id int,
primary key(team_id, vehicle_id)
)
