I get this:
100518 10:26:22 Error in foreign key constraint of table
seaflight/Passengers:
constraint foreign key (id) references Flights (flights_id), constraint
foreign key (id) references Customers (customer_id), name varchar(40),
weight tinyint(3)) engine=InnoDB:
Cannot resolve column name close to:
), constraint foreign key (id) references Customers (customer_id), name
varchar(40), weight tinyint(3)) engine=InnoDB
Here's my command:
create table if not exists Passengers (id int unsigned auto_increment
primary key, constraint foreign key (id) references Flights
(flights_id), constraint foreign key (id) references Customers
(customer_id), name varchar(40), weight tinyint(3)) engine=InnoDB;
I think I've got those constraints right. I'm calling the data from
those other tables, not the other way around. Please advise.
TIA,

I may be confused but how can the ID of the Passengers table be both the
ID of the Flight they are taking and their Customer ID at the same time?

You may want additional ID columns in the Passengers table to point to
the parent values in those other tables.
