【问题描述】：
我正在使用相关子查询来生成名为 SumDemerits 的运行总和，以便检查数据输入错误。 查询给出以下内容，其中包括原始表的副本：
DemeritID ID DemeritDate Amount DemeritType SumDemerits
83 42 5/23/2019 10 1 10
112 42 5/24/2019 -10 2 0

146 42 8/31/2019 -2 1 9
147 42 9/1/2019 2 1 11
150 42 9/2/2019 2 1 15
151 42 9/3/2019 -2 1 5
152 42 9/4/2019 -2 1 3
148 42 9/5/2019 -2 1 1
154 42 9/6/2019 10 1 11

167 42 11/15/2019 1 1 49
168 42 11/18/2019 3 1 52
169 42 11/19/2019 6 1 58
170 42 11/20/2019 30 2 88
运行总 SumDemerits 按预期工作，直到 2019 年 8 月 30 日突然给出 13 而不是 5。这是我的查询的 sql，它只是复制原始表并添加 SumDemerits 列。
SELECT Demerits.DemeritID, Demerits.ID, Demerits.DemeritDate, Demerits.Amount, Demerits.DemeritType, (SELECT Sum(dupe.[Amount]) FROM Demerits as dupe WHERE dupe.DemeritDate <= [Demerits].[DemeritDate]) AS SumDemerits
FROM Demerits
WHERE (((Demerits.ID)=[ID]))
ORDER BY Demerits.DemeritDate;
生成可以剪切和粘贴的表格版本的html代码：

</table>【问题讨论】：
-
如果您将数据发布为文本表格而不是代码行，则可以更轻松地导入表格和测试。事实上，它复制/粘贴为 1 个长文本字符串。尝试报告并使用文本框的 RunningSum 属性。看看你是否得到相同的结果。
-
访问报告在包含相关子查询时出错。最近的经验表明，解决方案是将报告基于临时表，但这意味着错误将持续存在于报告中。试图制作一个文本表；没有太大的成功。
-
在报告中使用运行总和文本框确实可以避免该错误。我不确定这是我想要的解决方案。
-
在那个 sn-p 上尽了最大的努力。这个问题现在看起来很糟糕；但至少生成的表格会正确剪切和粘贴
-
好的，效果很好。测试查询，没有得到问题。在 2019 年 10 月 7 日之前的计算是正确的。但是，2019 年 8 月 10 日有两条记录，并且都显示相同的总和。
