You have a table named Subcategories that contains subcategories for socks, vests and helmets. You have another table named Products that contains products only from the subcategories socks and vests. You have the following query:
SELECT s.Name, p.Name AS ProductName
FROM Subcategories s OUTER APPLY (SELECT * FROM Products pr WHERE pr.SubcategoryID = s.SubcategoryID) p
WHERE s.Name IS NOT NULL;
You need to predict the results of the query. What results should the query produce?
