Auto Relationship

Hi Team,

I would like to create a auto relationship between tables.

Currently i am using Northwind DB with tables (Orders, OrderDetails, Customers)

Orders ( OrderId, Customerid)

OrderDetails(OrderId)

Customers(CustomerID)

Now, if the user wants to generate a relationship automatically based on SAME FIELD Names.

What is the approach? Any kind of query or methodology

THanks
