If I understand your question correctly then a solution for your problem is: SELECT DISTINCT ca.Name AS AgeGroup , cn.Name AS CategoryName FROM Category AS ca INNER JOIN Category AS parentca ON ca.ParentCategoryID = parentca.CategoryID INNER JOIN ProductCategory AS prodca ON ca.CategoryID = prodca.CategoryID CROSS JOIN Category AS cn INNER JOIN Category AS parentcn ON cn.ParentCategoryID = parentcn.CategoryID INNER JOIN ProductCategory AS prodcn ON cn.CategoryID = prodcn.CategoryID WHERE ( parentca.Name = N'Books By Age' ) AND ( parentcn.Name = N'Kids Books' ) AND prodca.ProductID = prodcn.ProductID ORDER BY AgeGroup , CategoryName This works even if I add new pairs of data provided that I have correctly implemented your database design from your original question. CREATE TABLE Category ( name NVARCHAR(36) , parentcategoryid INT NULL , categoryid INT NOT NULL ) CREATE TABLE ProductCategory ( categoryid INT NOT NULL , productid INT NOT NULL, ) INSERT category ( name, parentcategoryid, categoryid ) VALUES ( 'Books By Age', 0, 1 ), ( 'Kids Books', 0, 2 ), ( 'Young Adult', 1, 3 ), ( 'Child', 1, 7 ), ( 'Action & Adventure', 2, 4 ), ( 'Castles & Dragons', 2, 8 ), ( 'Animal Stories', 2, 9 ), ( 'Stock Exchange Adventures', 2, 10 ) INSERT ProductCategory ( categoryid, productid ) VALUES ( 3, 30891 ), ( 4, 30891 ), ( 7, 30892 ), ( 8, 30892 ), ( 7, 30892 ), ( 9, 30892 ), ( 3, 30893 ), ( 10, 30893 ) I hope this helps!
