Hello, Here is 2 tables: airport --------- airport_id name code city_id destination ----------- destination_id dest_name ... airport_dep_id // using airport.airport_id (departure) airport_arr_id // using airport.airport_id has well (arrival) I have 2 columns in the second table that uses the same name column in the first table... I dont know how to formulate my SQL query... I want to select the destinations in the destination table with not the ID of each airport but their names. I can do a join with one but with the second one, I get no results... And this is confusing! select dest.dest_name, air.name as airport1, air.name as airport2 from destination, airport air where dest.airport_dep_id_id=air.airport_id and dest.airport_arr_id=air.airport_id; This is not good... Any help? Thanks! -- Marc Andre Paquin
