添加当月累积的行
有没有办法将我的硬编码 SQL 脚本转换为动态？
我对这段代码的问题是，它仍然添加了 SEPT-DEC 它应该是零，因为我们这个月还没有被覆盖
SELECT *,
[JAN] [JAN TO JAN] ,
[JAN] + [FEB] [JAN TO FEB] ,
[JAN] + [FEB] + [MAR] [JAN TO MAR],
[JAN] + [FEB] + [MAR] + [APR] [JAN TO APR] ,
[JAN] + [FEB] + [MAR] + [APR] + [MAY] [JAN TO MAY] ,
[JAN] + [FEB] + [MAR] + [APR] + [MAY] + [JUN] [JAN TO JUN] ,
[JAN] + [FEB] + [MAR] + [APR] + [MAY] + [JUN] + [JUL] [JAN TO JUL],
[JAN] + [FEB] + [MAR] + [APR] + [MAY] + [JUN] + [JUL] + [AUG] [JAN TO AUG],

FROM TEST_CHANNEL_YTD

预期结果：
从 JAN 开始，然后添加后续涵盖的月份。
回答
您可以对数据进行 UNPIVOT，使用窗口函数sum() over()计算运行总计，然后对结果进行 PIVOT。
例子
Select *
From (
Select Year
,Channels
,Col
,Amt
From TEST_CHANNEL_YTD A
Cross Apply (
Select Col
,Amt = sum(Amt) over (Order by Seq)
From (values ('Jan to Jan',1,Jan)
,('Jan to Feb',2,Feb)
,('Jan to Mar',3,Mar)
,('Jan to Apr',4,Apr)
,('Jan to May',5,May)
,('Jan to Jun',6,Jun)
,('Jan to Jul',7,Jul)
,('Jan to Aug',8,Aug)
,('Jan to Sep',9,Sep)
,('Jan to Oct',10,Oct)
,('Jan to Nov',11,Nov)
,('Jan to Dec',12,Dec)
) V (Col,Seq,Amt)
) B
) src
Pivot ( sum(Amt) for Col in ([Jan to Jan],[Jan to Feb],[Jan to Mar],[Jan to Apr],[Jan to May],[Jan to Jun],[Jan to Jul],[Jan to Aug],[Jan to Sep],[Jan to Oct],[Jan to Nov],[Jan to Dec]) ) pvt
结果
