按最近排序但由另一個ID列保持一致

Question

我想獲得一些排序和保持在一起（不是真正的分組）工作。 在我的示例數據中，我希望將DealerID保存在一起，按照IsPrimaryDealer DESC排序，但顯示最近輸入的經銷商的組（經銷商可能是分組）。

結果集2是最接近的，但格蘭特和他的兄弟應該按順序顯示爲前兩行。 （格蘭特應該是第1行，資助兄弟行2，因爲資助弟弟被最近添加的）

DECLARE @temp TABLE (
    DealerPK int not null IDENTITY(1,1), DealerID int, 
    IsPrimaryDealer bit, DealerName varchar(50), DateAdded datetime 
) 

INSERT INTO @temp VALUES 
(1, 1, 'Bob', GETDATE() - 7), 
(2, 1, 'Robert', GETDATE() - 7), 
(3, 1, 'Grant', GETDATE() - 7), 
(3, 0, 'Grants Brother', GETDATE() - 1), 
(2, 0, 'Roberts Nephew', GETDATE() - 2), 
(1, 0, 'Bobs Cousin', GETDATE() - 3) 

-- Data As Entered 
SELECT * FROM @temp 
-- Data Attempt at Row Numbering 
SELECT *, intPosition = 
    ROW_NUMBER() OVER (PARTITION BY IsPrimaryDealer ORDER BY DealerID, IsPrimaryDealer DESC) 
FROM @temp 
ORDER BY DateAdded DESC 
-- Data Attempt By DateAdded 
SELECT *, intPosition = 
    ROW_NUMBER() OVER (PARTITION BY DealerID ORDER BY DateAdded DESC) 
FROM @temp 
ORDER BY intPosition, DateAdded 

預期結果

PK DID IsPr Name   DateAdded 
3 3 1  Grant   2015-10-08 17:14:26.497 
4 3 0  Grants Brother 2015-10-14 17:14:26.497 
2 2 1  Robert   2015-10-08 17:14:26.497 
5 2 0  Roberts Nephew 2015-10-13 17:14:26.497 
1 1 1  Bob    2015-10-08 17:14:26.497 
6 1 0  Bobs Cousin  2015-10-12 17:14:26.497 

Answer 1

按照要求通過OP：

;WITH Cte AS(
    SELECT *, 
     mx = MAX(DateAdded) OVER(PARTITION BY DealerID) FROM @temp 
) 
SELECT * 
FROM Cte 
ORDER BY mx DESC, DealerID, IsPrimaryDealer DESC 

Answer 2

Hope i understood your question, 
This query results expected output : 

SELECT Row_number() 
       OVER (
        PARTITION BY DealerID 
        ORDER BY DealerPK)RN, 
       DealerPK, 
       DealerID, 
       IsPrimaryDealer, 
       DealerName, 
       DateAdded 
     FROM #temp 
     ORDER BY DealerID DESC
