Question

我有一个链接数据库，并创建了一个报告，汇总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 - 测试通过/失败的数量。一切正常，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 - 这是当前输出的数量。我有一个查询分析结果并分配通过/失败指定，并计算这些;我还创建了一个查询，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函数加起来测试的次数，但我需要样本的数量（即一个样本可以有5个不同的测试，并且可能只传递其中的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查询的副本：

计数实验室样本查询的副本：

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在报告中输出传递的测试次数，失败的测试次数和样本数作为单独的列。

如果这是可以接受的，你可以添加一个通过次数，并且计数失败，并且＃34; LabResultsAnalysisWithPass的复制查询＆＃34; （并删除现有的＆＃34; pass＆＃34;列）。然后在＆＃34; LabResultsAnalysisCountPass-Fail＆＃34;的复制中，对通过求和，对失败求和并计算＆＃34; LabProductSampleID＆＃34;。你根本不需要最后一个查询。

查询以计算传递/失败的测试数量的唯一样本ID
