我正在按照特定标准加入一些表格。我想知道是否还可以显示从联接中排除的那些记录的计数？

我的查询：

SELECT...

FROM         dbo.QuickLabDump 
             ...

             left outer join hermes.lom.dbo.lom_specimen Lom
              on QuickLabDump.[specimen id] = lom.specimen
              LEFT outer join SalesDWH.dbo.Isomers Isomers
              on QuickLabDump.[specimen id] = Isomers.[accession id]



WHERE     lom.specimen is null
              and isomers.[accession id] is null...

如您所见，我有两个左外连接。

除了这个查询的结果，我还想返回那些被排除的记录hermes.lom.dbo.lom_specimen的计数。SalesDWH.dbo.Isomers

我如何获得排除字段的计数？

这是完整的查询：

你在找这个吗？

SELECT      ...,
            (
              SELECT COUNt(*) FROM hermes.lom.dbo.lom_specimen WHERE specimen = lom.specimen
             ) AS ColCount

FROM         dbo.QuickLabDump    
             left outer join hermes.lom.dbo.lom_specimen Lom   
              on QuickLabDump.[specimen id] = lom.specimen   
              LEFT outer join SalesDWH.dbo.Isomers Isomers   
              on QuickLabDump.[specimen id] = Isomers.[accession id]   
WHERE     lom.specimen is null   
              and isomers.[accession id] is null

在没有 WHERE 子句的情况下运行相同的查询并使用 FULL OUTER JOIN 将为您提供可选 Universe 中的所有行。
