While creating table in SQL Server Management Studio Express, according to our logical data model, we need to combine two attributes to form unique id. Is it possible to combine two primary keys and set it? But while observing Northwind Sample, we found that in the ORDER DETAILS table, we can see two primary keys Order Id & Product Id .
