所以我觉得我做得很好。我做了5张桌子。tblComplexity、tblCoupling、tblLinesOfCode、tblMaintainIndex 和 tblProjects
tblProjects 有 2 列 [ID，项目名称]
其他 4 个表都有 3 列第 3 列是每个不同的列，正如您根据名称猜测的那样
4 个其他表 [ID*, RunID, (complexity,coupling,lines, MI)]
其他 4 个表中只有数字
我为 tblProjects.ID 和 (4tables).RunID 在 4 个表中的每一个上放置了多对 1 关系。
然后我为每个查询这是 qryComplexity
SELECT
tblProjects.ProjectName,
Round(Avg(tblComplexity.CyclomaticComplexity)+StDevP(tblComplexity.CyclomaticComplexity),2) AS MaxDeviation,
Max(tblComplexity.CyclomaticComplexity) AS MaxOfCyclomaticComplexity,
Min(tblComplexity.CyclomaticComplexity) AS MinOfCyclomaticComplexity,
Round(Avg(tblComplexity.CyclomaticComplexity)-StDevP(tblComplexity.CyclomaticComplexity),2) AS MinDeviation
FROM
tblProjects
INNER JOIN
tblComplexity
ON tblProjects.ID = tblComplexity.RunID
GROUP BY
tblProjects.ProjectName;
所有这 4 个查询都给了我想要的数字（我曾经在一张 excel 表中拥有这一切。）
我最终的目标是将这个数据库与 excel 连接起来，这样我就可以有我的图表了。问题是这就是我的 excel 表的样子（以及其中一个选项卡）

这就是我的查询返回的

所以我试着把我的行加起来……我得到了一些疯狂的数字。那么如何将我的代码行放入每个查询中呢？哦，我想我应该把我的 qryLinesOfCode
SELECT
tblProjects.ProjectName,
Sum(tblLinesOfCode.LinesOfCode) AS LinesOfCode
FROM
tblProjects
INNER JOIN
tblLinesOfCode
ON tblProjects.ID = tblLinesOfCode.RunID
GROUP BY
tblProjects.ProjectName;
我认为只为我的 3 个查询中的每一个添加另一个内部连接会很简单（是的 3..第 4 个是代码行，但我的 excel 表只有 3 个选项卡）..所以我尝试了这个
SELECT
tblProjects.ProjectName,
Sum(tblLinesOfCode.LinesOfCode) AS LinesOfCode
Round(Avg(tblComplexity.CyclomaticComplexity)+StDevP(tblComplexity.CyclomaticComplexity),2) AS MaxDeviation,
Max(tblComplexity.CyclomaticComplexity) AS MaxOfCyclomaticComplexity,
Min(tblComplexity.CyclomaticComplexity) AS MinOfCyclomaticComplexity,
Round(Avg(tblComplexity.CyclomaticComplexity)-StDevP(tblComplexity.CyclomaticComplexity),2) AS MinDeviation
FROM
((tblProjects
INNER JOIN
tblComplexity
ON tblProjects.ID = tblComplexity.RunID)
INNER JOIN
tblLinesOfCode
ON tblProjects.ID = tblLinesOfCode.RunID)
GROUP BY
tblProjects.ProjectName;
但我明白了

Project9 12065 99.94 100 57 69.26
Project10 4238 103.45 100 65 81.33
有人可以帮我吗？谢谢
PS。我正在使用 Access/Excel 2010
