Résumez l'agrégat dans SQL Server ou ORACLE

Question

Je cours la requête ci-dessous et devez inclure un total en bas mais je ne sais pas comment l'exécuter dans SQL SERVER. (Je peux copier les données et faire une somme automatique dans Excel mais c'est un peu répétitif) Quelqu'un pourrait-il m'aider?

SELECT 
LOCATION, 
SUM(CASE WHEN my_date >= '10/1/2009' AND my_date <'01/01/2010' THEN QTY 
    ELSE NULL END) AS QTR1, 

SUM(CASE WHEN my_date >= '01/1/2010' AND my_date <'04/01/2010' THEN QTY 
    ELSE NULL END) AS QTR2, 

SUM(CASE WHEN my_date >= '04/1/2010' AND my_date <'07/01/2010' THEN QTY 
    ELSE NULL END) AS QTR3, 

SUM(CASE WHEN my_date >= '07/1/2010' AND my_date <'10/01/2010' THEN QTY 
    ELSE NULL END) AS QTR4 
FROM MYTABLE 
GROUP BY location 



Location QTR1 QTR2 QTR3 QTR4 
FL 171  174  99  177 
MD 662  640  422  497 
VA 2,713 4,454 3,062 2,793 
NY 479  380  227  477 
PA 7,197 10,078  5,625 6,448 
NJ 2,626 3,848 2,428 2,089 
TOTAL ??? ??? ??? ???

Est-ce GROUP BY LOCATION WITH ROLLUP faire ce que vous avez besoin?

;WITH MYTABLE AS 
(
SELECT 'FL' AS LOCATION,CAST('10/1/2009' AS DATETIME) AS my_date, 1 AS QTY UNION ALL 
SELECT 'MD' AS LOCATION,'10/1/2009' AS my_date, 27 AS QTY UNION ALL 
SELECT 'MD' AS LOCATION,'01/1/2010' AS my_date, 1024 AS QTY UNION ALL 
SELECT 'FL' AS LOCATION,'07/1/2010' AS my_date, 98 AS QTY UNION ALL 
SELECT 'FL' AS LOCATION,'07/1/2010' AS my_date, 5 AS QTY 
) 
SELECT 
COALESCE(LOCATION,'TOTAL'), 
SUM(CASE WHEN my_date >= '10/1/2009' AND my_date <'01/01/2010' THEN QTY 
    ELSE NULL END) AS QTR1, 
SUM(CASE WHEN my_date >= '01/1/2010' AND my_date <'04/01/2010' THEN QTY 
    ELSE NULL END) AS QTR2, 
SUM(CASE WHEN my_date >= '04/1/2010' AND my_date <'07/01/2010' THEN QTY 
    ELSE NULL END) AS QTR3, 
SUM(CASE WHEN my_date >= '07/1/2010' AND my_date <'10/01/2010' THEN QTY 
    ELSE NULL END) AS QTR4 
FROM MYTABLE 
GROUP BY LOCATION WITH ROLLUP 

Retours

 QTR1  QTR2  QTR3  QTR4 
----- ----------- ----------- ----------- ----------- 
FL 1   NULL  NULL  103 
MD 27   1024  NULL  NULL 
TOTAL 28   1024  NULL  103 

Answer 2

Je pense qu'une variante de ceci devrait fonctionner. Il suffit de retirer le regroupement par emplacement et utilisez cette requête:

SELECT SUM(CASE WHEN my_date >= '10/1/2009' AND my_date <'01/01/2010' THEN QTY ELSE NULL END) AS QTR1, 

SUM(CASE WHEN my_date >= '01/1/2010' AND my_date <'04/01/2010' THEN QTY ELSE NULL END) AS QTR2, 

SUM(CASE WHEN my_date >= '04/1/2010' AND my_date <'07/01/2010' THEN QTY ELSE NULL END) AS QTR3, 

SUM(CASE WHEN my_date >= '07/1/2010' AND my_date <'10/01/2010' THEN QTY ELSE NULL END) AS QTR4 FROM MYTABLE
