查询以计算通过/失败的测试数量的唯一样本 ID

Question

我有一个链接数据库，并创建了一份报告，总结了在指定日期范围内测试的样本：产品、产品组、产品描述、测试描述 - 有多少人通过/失败了该测试。一切都很好，除了我需要计算每个产品组测试的样本数量而不是测试数量——这是当前输出的。我有一个查询，它分析结果并分配通过/失败指定，这些都被计算在内；我还创建了一个查询，该查询计算提交的样本数量（也在日期范围之间），但无法弄清楚如何将其合并到用于报告的主查询中。 sum 函数将测试的数量相加，但我需要样本的数量（即一个样本可能有 5 个不同的测试，并且只能通过其中的 2 个）。我很难将 2 + 2 放在一起！ I've attached an image of my report design to help visualize

LabResultsAnalysisCountPass-Fail查询副本：

SELECT DISTINCTROW [Copy of LabResultsAnalysisWithPass Query].Name, [Copy of    LabResultsAnalysisWithPass Query].Plant, [Copy of LabResultsAnalysisWithPass Query].ProductGroup, [Copy of LabResultsAnalysisWithPass Query].ProductDescription, [Copy of LabResultsAnalysisWithPass Query].TestDescription, [Copy of LabResultsAnalysisWithPass Query].Pass, Count([Copy of LabResultsAnalysisWithPass Query].Pass) AS CountOfPass
FROM [Copy of Count Lab Samples Query], LabProductTest INNER JOIN [Copy of LabResultsAnalysisWithPass Query] ON LabProductTest.LabProductTestID = [Copy of LabResultsAnalysisWithPass Query].LabProductTestID
GROUP BY [Copy of LabResultsAnalysisWithPass Query].Name, [Copy of LabResultsAnalysisWithPass Query].Plant, [Copy of LabResultsAnalysisWithPass Query].ProductGroup, [Copy of LabResultsAnalysisWithPass Query].ProductDescription, [Copy of LabResultsAnalysisWithPass Query].TestDescription, [Copy of LabResultsAnalysisWithPass Query].Pass, LabProductTest.Deleted
HAVING (((LabProductTest.Deleted)=False));

LabResultsAnalysisWithPass 查询副本：

ORDER BY PlantInformation.Name, ProductGroup.ProductGroupCode, ProductGroup.ProductGroup, LabTestProvincialStandard.TestDescription;

Count Lab Samples 查询副本：

PARAMETERS [Enter Lab Results start date] DateTime, [Enter Lab Results end date] DateTime;
SELECT PlantInformation.Plant, PlantInformation.Name, Count(LabProductSample.LabProductSampleID) AS CountOfLabProductSampleID, LabPlantSample.SampleDate

GROUP BY PlantInformation.Plant, PlantInformation.Name, LabPlantSample.SampleDate, LabProductSample.Deleted
HAVING (((LabPlantSample.SampleDate) Between [Enter Lab Results start date] And [Enter Lab Results end date]) AND ((LabProductSample.Deleted)=False));

Answer 1

也许最简单的解决方案是将通过测试的数量、失败的测试数量和样本数量作为单独的列输出到报告中。

如果可以接受，您可以在“复制 LabResultsAnalysisWithPass 查询”中添加通过和失败计数（并删除现有的“通过”列）。然后在“LabResultsAnalysisCountPass-Fail 的副本”中，将通过次数、失败次数和计数“LabProductSampleID”相加。您根本不需要最后一个查询。
