Question

您好我在尝试执行以下查询时收到此错误。有什么想法或建议吗？

错误：＆＃34;在包含外部引用的聚合表达式中指定了多个列。如果聚合的表达式包含外部引用，则该外部引用必须是表达式中引用的唯一列。＆＃34;

Answer 1

问题在于你无法在聚合函数

中组合外部和内部引用

(SELECT TOP 100 PERCENT SUM(CASE WHEN bands.StackPosition = b.StackPosition THEN 1 ELSE 0 END) * 100/ CASE

WHEN COUNT(StudentScores_Subject.pkStudentScoreID) = 0 THEN 1

ELSE COUNT(StudentScores_Subject.pkStudentScoreID)

 END
   FROM PerformanceLevelReportBands b
   WHERE b.fkPerformanceLevelReportID = @intPerfLevelReportId
   ORDER BY SUM(CASE WHEN bands.StackPosition = b.StackPosition THEN 1 ELSE 0 END) * 100/ CASE

WHEN COUNT(StudentScores_Subject.pkStudentScoreID) = 0 THEN 1

ELSE COUNT(StudentScores_Subject.pkStudentScoreID)

END) AS 'Percent'

所以将其改为

(SELECT TOP 100 PERCENT SUM(CASE WHEN bb.StackPosition = b.StackPosition THEN 1 ELSE 0 END) * 100/ CASE

  WHEN COUNT(StudentScores_Subject.pkStudentScoreID) = 0 THEN 1

  ELSE COUNT(StudentScores_Subject.pkStudentScoreID)

 END
   FROM PerformanceLevelReportBands b JOIN PerformanceLevelReportBands bb
    ON bb.fkPerformanceLevelReportID =bands.fkPerformanceLevelReportID 
    AND b.fkPerformanceLevelReportID =bb.fkPerformanceLevelReportID
   WHERE b.fkPerformanceLevelReportID = @intPerfLevelReportId
   ORDER BY SUM(CASE WHEN bb.StackPosition = b.StackPosition THEN 1 ELSE 0 END) * 100/ CASE

 WHEN COUNT(StudentScores_Subject.pkStudentScoreID) = 0 THEN 1

 ELSE COUNT(StudentScores_Subject.pkStudentScoreID)

 END) AS 'Percent'

这是更多thorough explanation。

Answer 2

我建议评论bandComponents然后cutScores，在删除每个组件后重新运行并查看查询失败的位置。一旦你找出它失败的地方，你就可以解决它。

此外，可能是此行，即您的百分比列中的查询。

ORDER BY SUM(CASE WHEN bands.StackPosition = b.StackPosition THEN 1 ELSE 0 END) * 100

我尝试更好地整理您的查询，以使其更清晰。

SELECT 
    TestInstances.pkTestInstanceID                      AS 'pkTestInstanceID'
    , bands.pkPerformanceLevelReportBandID              AS 'BandID'
    , bands.StackPosition                               AS 'StackPosition'
    , (
        SELECT TOP 100 PERCENT 
            SUM( CASE 
                    WHEN bands.StackPosition = b.StackPosition 
                    THEN 1 
                    ELSE 0 
                    END) * 100 / 
                CASE 
                    WHEN COUNT(StudentScores_Subject.pkStudentScoreID) = 0 
                    THEN 1 
                    ELSE COUNT(StudentScores_Subject.pkStudentScoreID)

Answer 3

我遇到了相同的问题或类似的问题。为了帮助您，我在这里留下了初始代码和解决方案。

初始代码：

SELECT ISNULL((SELECT DateName(mm,DATEADD(mm,Perioada - 1,0))),'Nedefinit') as [Period],MAX(t.TipPerioada) AS TipPerioada,t.Perioada,MAX(t.An) AS An, a.NumePrenume, CAST(t.Volum as float) as ValTip,
            ISNULL((Select Sum(v.Cantitate*p.VolumProdus)
                    From Wme_Vanzari as v 
                    WHERE ('ND'='ND' or v.MarcaAgent = t.MarcaAgent) and  t.[An]=v.AnFactura  and t.Perioada=v.Lunafactura),0) as Realizat,
            '' as Diferenta,'' as DiferentaWD,'' as Procent
            FROM  [Memo_Target] t
            --Aduce Suma de Cantitate si MarcaAgent pentru a nu dubla cu liniile din Vanzari 
            LEFT JOIN (Select SUM(Cantitate) as Cantitate, MarcaAgent 
                        From Wme_Vanzari  
                        WHERE AnFactura = @An 
                        GROUP BY MarcaAgent) v on t.MarcaAgent = v.MarcaAgent
            LEFT JOIN WME_Agenti a on a.Marca = t.MarcaAgent
            --Aduce Suma de VolumProdus, CodProdus si Marca Agent Filtrat dupa Anul dat in parametru, Volum necesar pt a calcula Realizat si a scade din targetul setat
            LEFT JOIN  (SELECT SUM(ISNULL(n.VolumProdus, 0)) AS VolumProdus, v.CodProdus, v.MarcaAgent
                        FROM Wme_NomenclatorProduse n
                        LEFT JOIN Wme_Vanzari v ON v.CodProdus = n.CodIntern
                        WHERE v.MarcaAgent IS NOT NULL AND v.CodProdus IS NOT NULL  AND v.AnFactura = @An
                        GROUP BY v.CodProdus, v.MarcaAgent  ) p ON p.MarcaAgent = t.MarcaAgent
            WHERE (t.Volum IS NOT NULL AND t.Volum > 0)
            AND t.An = @An
            AND (CAST(t.Perioada AS INT) BETWEEN @lunastart AND @lunaend)
            AND TipTarget = @tiptarget
            AND (a.Marca IN (SELECT * FROM dbo.GetIdsTableString(@marcaAgent)) OR @marcaAgent = 'ND')
            GROUP BY a.NumePrenume, t.Volum, Perioada,t.An

错误消息是相同的，这是解决方法代码：

SELECT ISNULL((SELECT DateName(mm,DATEADD(mm,Perioada - 1,0))),'Nedefinit') as [Period],MAX(t.TipPerioada) AS TipPerioada,t.Perioada,MAX(t.An) AS An, a.NumePrenume, CAST(t.Volum as float) as ValTip,
            (ISNULL((Select Sum(p.VolumProdus)
                    From Wme_Vanzari as v 
                    WHERE ('ND'='ND' or v.MarcaAgent = t.MarcaAgent) and  t.[An]=v.AnFactura  and t.Perioada=v.Lunafactura),0) * sum(v.Cantitate)) as Realizat,
            '' as Diferenta,'' as DiferentaWD,'' as Procent
            FROM  [Memo_Target] t
            --Aduce Suma de Cantitate si MarcaAgent pentru a nu dubla cu liniile din Vanzari 
            LEFT JOIN (Select SUM(Cantitate) as Cantitate, MarcaAgent 
                        From Wme_Vanzari  
                        WHERE AnFactura = @An 
                        GROUP BY MarcaAgent) v on t.MarcaAgent = v.MarcaAgent
            LEFT JOIN WME_Agenti a on a.Marca = t.MarcaAgent
            --Aduce Suma de VolumProdus, CodProdus si Marca Agent Filtrat dupa Anul dat in parametru, Volum necesar pt a calcula Realizat si a scade din targetul setat
            LEFT JOIN  (SELECT SUM(ISNULL(n.VolumProdus, 0)) AS VolumProdus, v.CodProdus, v.MarcaAgent
                        FROM Wme_NomenclatorProduse n
                        LEFT JOIN Wme_Vanzari v ON v.CodProdus = n.CodIntern
                        WHERE v.MarcaAgent IS NOT NULL AND v.CodProdus IS NOT NULL  AND v.AnFactura = @An
                        GROUP BY v.CodProdus, v.MarcaAgent  ) p ON p.MarcaAgent = t.MarcaAgent
            WHERE (t.Volum IS NOT NULL AND t.Volum > 0)
            AND t.An = @An
            AND (CAST(t.Perioada AS INT) BETWEEN @lunastart AND @lunaend)
            AND TipTarget = @tiptarget
            AND (a.Marca IN (SELECT * FROM dbo.GetIdsTableString(@marcaAgent)) OR @marcaAgent = 'ND')
            GROUP BY a.NumePrenume, t.Volum, Perioada,t.An

如您所见，我选择在第一个子选择中保留一列，并且在此子选择后我被迫使用乘法运算。希望对您有所帮助！

错误：＆＃34;在包含外部引用的聚合表达式中指定了多个列。＆＃34;
