Hello! Please, if we have different tables in our db and want to get for certain names BMIs (from their mass and height values form other tables), and if we want to insert to a certain table values mass*height whichare in other tables , how can we make the formula at inserting to do it authomattically? Hope U understood me. Sth like that is not a problem to do in excell, where we have cells with values AND names. Is sth like that possible in sql developer? many thanks!!!
