如何根据累积值创建总计

Question

我创建了一个报告，该报告显示了每个损失月份（打开和关闭索赔时）的累计总额。下图可能会更好地说明这一点：

y轴为损失日期的月份-x轴为索赔打开或关闭的月份。这是从左到右的累计总数。

例如，在2014年1月-共有5项未结索赔，而一项已结案。然后在2014年2月-又提出了两项​​索赔，而第二项索赔却被关闭。

图像中黄色突出显示的单元格是我无法计算的值。要获得单个损失月份的总数-我使用了一个Windows函数来获取最大值，并按年份，索赔月份和索赔状态进行了划分-

MAX( ClaimCount ) OVER (PARTITION BY Year, ClaimMonth, ClaimStatus)

对我来说不幸的是，我一直无法弄清楚如何计算索赔总数（已结案和总数）的总计。

下面是示例数据：

CREATE TABLE #claimcount
(
    Year INT NULL,
    ClaimStatus VARCHAR (25) NULL,
    LossMonth DATE NULL,
    ClaimMonth DATE NULL,
    ClaimCount INT NULL,
    ClaimTotalPerLossMonth INT NULL,
    ClaimTotalPerClaimMonth INT NULL,
    ClaimCountPerLossYear INT NULL
);
INSERT INTO #claimcount
(
    Year,
    ClaimStatus,
    LossMonth,
    ClaimMonth,
    ClaimCount,
    ClaimTotalPerLossMonth,
    ClaimTotalPerClaimMonth,
    ClaimCountPerLossYear
)

GROUP BY Year,

SELECT *

DROP TABLE #claimcount;

Answer 1

我不确定我是否正确理解了您的问题，但是也许您正在寻找类似的东西：

SELECT x.Year, x.ClaimStatus, x.LossMonth, 
    SUM(MaxClaimTotalPerLossMonth) AS MaxClaimTotalPerLossMonth
FROM (
    SELECT Year, ClaimStatus, LossMonth,
           MAX ( ClaimTotalPerLossMonth ) AS MaxClaimTotalPerLossMonth
    FROM #claimcount
    GROUP BY Year, ClaimStatus, LossMonth
) x GROUP BY GROUPING SETS ((Year, ClaimStatus, LossMonth), (Year, ClaimStatus));

Answer 2

只需将您要计算的内容放入CTE中，就可以将其总计为总粒度：

;with t as(
SELECT Year,
       ClaimStatus,
       LossMonth,
       MAX ( ClaimTotalPerLossMonth )MaxClaims
       , sum(ClaimTotalPerLossMonth)ClaimCountPerLossYear
       , sum(ClaimTotalPerClaimMonth)ClaimTotalPerClaimMonth
       , sum(ClaimCount)ClaimCount
FROM #claimcount
GROUP BY Year,
         ClaimStatus,
         LossMonth
)
select * from t
union all
select 0,'GRAN TOTAL',NULL,sum(MaxClaims),sum(ClaimCountPerLossYear)
    ,sum(ClaimTotalPerClaimMonth),sum(ClaimCount)
from t
