ALTER TABLE ORDERS
ADD FOREIGN KEY (customer_sid) REFERENCES CUSTOMER(SID);
How do i add several keys with SQL Server? is it something like the below? (I cant test ATM and unfortunately i have no way to test queries unless i run it through code)
ALTER TABLE ORDERS
ADD FOREIGN KEY (customer_sid) REFERENCES CUSTOMER(SID),
ADD FOREIGN KEY (customer_sid2) REFERENCES CUSTOMER(SID2);
or is it like
ALTER TABLE ORDERS
ADD FOREIGN KEY (customer_sid, customer_sid2) REFERENCES CUSTOMER(SID, SID2)
