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));
