USE AdventureWorks2008R2;
GO
SELECT ProductID

INTERSECT
SELECT ProductID
FROM Production.WorkOrder ;

USE AdventureWorks2008R2;
GO
SELECT DISTINCT Production.WorkOrder.ProductID
FROM Production.Product
INNER JOIN Production.WorkOrder ON Production.WorkOrder.ProductID = Production.Product.ProductID
