i have this:

id depart arrive type journeyNumber
123 car bus 4 1
123 bus van 4 2
456 car bus 2 1
999 bus van 2 1

type=4 meants connecting route, type=2 means none connecting route.
arrive=van are from US country.

i would like to pull out all which has connecting route and from US country.

i did this but it only come out as below:

select * from tableA inner join tableB on tableA.contry=tableB.country where type=4 and country=US

id depart arrive type journeyNumber
123 bus van 4 2

it suppose to come out as below:

id depart arrive type journeyNumber
123 car bus 4 1
123 bus van 4 2

Does it mean that you want to return all rows for IDs associated with the result?

Maybe this?


select * 
from (select *,SUM(CASE WHEN type=4 and country='US' THEN 1 ELSE 0 END) OVER (PARTITION BY ID) AS Cnt 
      FROM tableA 
      )a
inner join tableB b 
on a.contry=b.country 
WHERE a.Cnt > 0
