Sonuç kümesinin son satırındaki tüm sütun değerlerinin toplamı nasıl alınır?

Question

Son satırda sonuç kümesinin tüm sütun değerlerinin toplamını almam gerekiyor.
İşte SQL sorgum. Böyle

select Master_Code, SUM(Jan), SUM(Feb), SUM(Mar) 
from dbo.foobar 
WHERE Participating_City = 'foofoo' 
GROUP BY Master_Code ORDER BY Master_Code ASC 

şey:

Master_Code Jan Feb Mar 
    1   4 5 6 
    2   5 5 5 
    Total  9 10 11 

Answer 1

hiçbir boş master_code satır vardır.

SELECT ISNULL(Master_code, 'Total') AS Master_Code, 
     Jan, 
     Feb, 
     Mar 
FROM (
     SELECT Master_code, 
      SUM(Jan) AS Jan, 
      SUM(Feb) AS Feb, 
      SUM(Mar) AS Mar 
     FROM foobar 
     WHERE Participating_City = 'foofoo' 
     GROUP BY Master_code WITH ROLLUP 
    ) AS DT 

Answer 2

aynı sorguyu ama gruplaşma olmadan tekrar bir birlik olun: varsayarsak

select Title, Jan, Feb, Mar 
from (
    select Master_Code as Title, SUM(Jan) as Jan, SUM(Feb) as Feb, SUM(Mar) as Mar 
    from dbo.foobar 
    WHERE Participating_City = 'foofoo' 
    GROUP BY Master_Code ORDER BY Master_Code ASC 
) x 
union all 
select 'Total', SUM(Jan) as Jan, SUM(Feb) as Feb, SUM(Mar) as Mar 
from dbo.foobar 
WHERE Participating_City = 'foofoo' 

Answer 3

Ayrıca Coalesce ve Rollup ile de kullanabilirsiniz.

SELECT COALESCE(Master_Code, 'TOTAL') AS MASTER_CODE, SUM(Jan), SUM(Feb), SUM(Mar) 
FROM dbo.foobar 
WHERE Participating_City = 'foofoo' 
GROUP BY Master_Code WITH ROLLUP 
ORDER BY Master_Code DESC
