如何使用SUM和OVER
我使用Sum（）Over（Partition by ... Order by ..）函数来计算列的运行总计，但只要重复（或重复）该值就会出现问题。 Sum（）似乎按值对它们进行分组，并将所有按值组合的总和作为移动总和。这不是我打算实现的目标。任何关于它为什么以重复值的形式发生的想法或输入，以及如何在不按行列进行游标循环的情况下实现正确的运行总计，深受赞赏。下面是测试表的详细信息及其数据，并附加了一个包含预期结果的文件（附件中突出显示的列是Oracle Sum（）计算错误的内容）。

我使用计算我的运行总计的查询如下 -
SELECT A1,A2,A2SUBCLASS,DENSERNK,A2CONTRI,
SUM(A2CONTRI) OVER (PARTITION BY A1,A2SUBCLASS,DENSERNK ORDER BY A2CONTRI
asc) AS RUNTOTA2CONTRI
FROM RUNNINGTOTAL_TEST1
ORDER BY A2SUBCLASS ASC;

默认情况下，分析函数使用RANGE窗口指令（请参阅下文 - 默认为第一个版本）。您正在寻找的是ROWS指令（见下文），它不是默认值，因此您必须明确包含它。
RANGE窗口子句（默认）完全符合您的注意：它将所有“绑定”行视为“包含在总和中”。

问题是关于Oracle，我的回答是基于DB2 OLAP实现 - 它有不同的默认值。有关正确的Oracle语法，请参阅@ mathguy的答案。
如果你想要一个运行总和，请不要使用分区，除了你希望运行总和为“span”的范围外，它将按部分顺序排序，在此问题中无效或具体足够的，目前尚不清楚你正在使用什么订单 - 我在下面猜测 - 应该是关闭的。
SELECT A1,A2,A2SUBCLASS,DENSERNK,A2CONTRI,
SUM(A2CONTRI) OVER (ORDER BY DESNSERNK, A2, A2CONTRI) AS RUNTOTA2CONTRI
FROM RUNNINGTOTAL_TEST1
