Hi Friend,

A foreign key is a field (or fields) that points to the primary key of another table.

CREATE TABLE CUSTOMER
(SID integer,
 FirstName varchar(40),
 LastName varchar(40),
Primary Key (SID ));

CREATE TABLE ORDERS
(Order_ID integer,
Order_Date date,
Customer_SID integer,
Amount double,
Primary Key (Order_ID),
Foreign Key (Customer_SID) references CUSTOMER(SID));

Thanks
