I want to Select records from distinct categories. I requirment is to select records order by AddedDate with distinct CategoryId.

SELECT [Name], [refCategory], [Added]
  FROM(
    SELECT [refCategory],
       [Added],
       [Name],
       row_number() OVER (
           PARTITION BY [refCategory]
           ORDER BY [Added] ASC
       ) AS [catGroup]
      FROM @Product
     GROUP BY [refCategory], [Added], [Name]
   ) AS ProductCTE
WHERE [catGroup] <= 2
ORDER BY [refCategory] ASC, [Added] ASC

SELECT p.refCategory, t.Name, t.Added 
FROM 
(SELECT DISTINCT refCategory
	FROM @Product) p
	CROSS APPLY 
		(SELECT TOP 1 Name, Added
			FROM @Product
			WHERE refCategory = p.refCategory
			ORDER BY Added ASC) t
