Question

I have two sets of elements A:[1,2,3,4] and B:[5,6,7,8] and I would like to know if it’s possible to make a query to select all the stations that contain at least one element in A and one element in B

SELECT * FROM Stations WHERE myStation.lines correspond to at least one in A AND at least one in B

myStation.lines is also a set of elements…

Thanks!!!

Answer 1

I think you are asking for this:

select * from Stations where lines IN 
(select distinct [column_name] from A) AND 
lines in (select distinct [column_name] from B)
