The query is based on the AdventureWorks Sales Model. To compile and run this query, follow these steps:

  1. Follow the procedure in How to: Execute a Query that Returns StructuralType Results.

  2. Pass the following query as an argument to the ExecuteStructuralTypeQuery method:

(SELECT product 
    FROM AdventureWorksEntities.Products AS product 
    WHERE product.ListPrice > @price1 ) 
    intersect (SELECT product FROM AdventureWorksEntities.Products AS 
    product WHERE product.ListPrice > @price2)
