using (AdventureWorksEntities context =
new AdventureWorksEntities())
{
string queryString = @"SELECT VALUE product
FROM AdventureWorksEntities.Products AS product
WHERE product.ProductID < @productID";
ObjectQuery<Product> productQuery =
new ObjectQuery<Product>(queryString,
context, MergeOption.NoTracking);
ObjectQuery<Product> productQuery2 =
new ObjectQuery<Product>(queryString,
context, MergeOption.NoTracking);
ObjectQuery<Product> productQuery3 =
productQuery.Union(productQuery2);
productQuery3.Parameters.Add(new ObjectParameter("productID", productID));
Console.WriteLine("Result of Union");

// Iterate through the collection of Product items,
// after the Union method was called on two queries.
foreach (Product result in productQuery3)
{
