SQL Server PIVOT 多列

Question

我已經搜索了多個支點，但仍然沒有找到與我相似的支點。 我正在使用 SQL Server 2008。

我已經用pivot創建了一個查詢：

select * 
from 
    (select 
         branch, sum(balance) [balance], 
         year(docdate) [year], month(docdate) [month]
     from 
         tempprt 
     group by 
         branch, year(docdate), month(docdate)) as a
pivot 
    (sum(balance) 
     for month in ([1], [2])) as pvt1

我得到這個輸出：

現在，我想對每年的第1列和第2列求和，並將年份作為列：

感謝您的幫助。 謝謝！

您可以在下面的腳本中嘗試此操作-

select branch,

SUM(CASE WHEN year(docdate) = 2019 THEN balance ELSE 0 END) [2019],
SUM(CASE WHEN year(docdate) = 2019 AND MONTH(docdate) = 1 THEN balance ELSE 0 END) [2019_1],
SUM(CASE WHEN year(docdate) = 2019 AND MONTH(docdate) = 2 THEN balance ELSE 0 END) [2019_2],

SUM(CASE WHEN year(docdate) = 2018 THEN balance ELSE 0 END) [2018],
SUM(CASE WHEN year(docdate) = 2018 AND MONTH(docdate) = 1 THEN balance ELSE 0 END) [2018_1],
SUM(CASE WHEN year(docdate) = 2018 AND MONTH(docdate) = 2 THEN balance ELSE 0 END) [2018_2]

from tempprt 
GROUP BY branch
