Good evening, I've been trying to make this query, but unfortunately, I can not find the way to put the name of the state of origin and destination.
The Diagram itself is too extensive, but in this particular part it is where I do not understand how I can do it.
I know the next query is wrong, but it is to let them understand what I want to show.
SELECT E.nombre as Estado_Origen, E.nombre as Estado_Destino FROM ORIGEN O, DESTINO D, ESTADO E WHERE O.id_estado = E.id_estado AND D.id_estado = E.id_estado
PDTA: I'm still starting, and my teacher does not like it very much that I use the INNER JOIN'S, but I can gladly learn for this kind of consultations.
Thank you very much!
