【问题描述】：
我正在使用 Excel Power Query Editor 来查询我的数据库以将信息提取到 Excel 中，以便我可以轻松地操作这些信息以用于报告目的。我在 Microsoft SQL 中编写了一个查询并将其粘贴到 Power Query 编辑器中。我有一个非常愚蠢的查询，只是使用下面代码片段中显示的参数表和函数按表中的日期过滤数据。
fParameters 只是抓取一个包含 2 个包含开始和结束日期（周开始，周末）的单元格的表格。该查询将抓取几行 100k 行，然后使用 fParameters 将其过滤到那一周我需要的几百行。
我编写了一个新查询，以便获取更多需要的信息，问题是我正在使用 DECLARE 语句来设置这些开始/结束日期，并且在之后简单地过滤查询不再是一种选择。
这可能比我做的更容易，但是有什么方法可以简单地将单元格的值传递到我的查询中？

基本上，我只希望前 2 行中的那些日期用于声明开始和结束日期来自我在我的 excel 工作表中的 2 个单元格。 然后是我的查询和其他计算此表中的内容将一起更新。
【问题讨论】：

这应该有助于展示如何在 Power Query 中获取单元格值：stackoverflow.com/questions/49281763
-
@AlexisOlson 那么我是否可以让 Start_Date = Excel ......[Name="Start_Date"]....如果我将单元格命名为 Start_Date？
-
看起来不错。您使用您引用的范围的名称并从该范围中选择行和列以获得单个值（这是
[Content]{0}[Column1]部分）。 -
LET Start_Date = Excel.CurrentWorkbook(){[Name="Start_Date"]}[内容]{0}[Column1] End_Date = Excel.CurrentWorkbook(){[Name="End_Date"]} [内容]{0}[Column2] DECLARE (at)StartDate DATE = Start_Date DECLARE (at)EndDate DATE = End_Date @AlexisOlson 这样吗？
-
您需要确保您没有尝试将它们作为字符串文字传递。见这里，例如：stackoverflow.com/questions/64882066
