Sql server SQL-不能在Group子句中使用子查询的聚合

我试图在下面的查询中按[DueDate]分组，但根据设置，该日期可能会有所不同。有什么办法可以让这一切顺利吗

SELECT
(
    SELECT CASE 
    WHEN (SELECT TOP 1 [SiconCFMSetting].[SettingValue] FROM [SiconCFMSetting] WHERE [SiconCFMSetting].[SettingName]='UseAverageTimeToPay') = 'True'
    THEN ISNULL([SiconCFMForecastDate].[ForecastDate],DATEADD([DD],[SiconCFMSLCustomerAverageTimeToPayView].[Days],[SLPostedCustomerTran].[TransactionDate]))
    ELSE ISNULL([SiconCFMForecastDate].[ForecastDate],[SLPostedCustomerTran].[DueDate])
    END
) AS [DueDate],
SUM([SLPostedCustomerTran].[SalControlValueInBaseCurrency]) AS [Value]
FROM        [SLPostedCustomerTran]
INNER JOIN  [SLCustomerAccount]
ON          [SLCustomerAccount].[SLCustomerAccountID]
=           [SLPostedCustomerTran].[SLCustomerAccountID]
INNER JOIN  [SiconCFMSLCustomerAverageTimeToPayView]
ON          [SiconCFMSLCustomerAverageTimeToPayView].[SLCustomerAccountID]
=           [SLCustomerAccount].[SLCustomerAccountID]
LEFT JOIN   [SiconCFMForecastDate]
ON          [SiconCFMForecastDate].[ForecastDateForeignID]
=           [SLPostedCustomerTran].[SLPostedCustomerTranID]
AND         [SiconCFMForecastDate].[Deleted]=0
AND         [SiconCFMForecastDate].[ForecastDateSource]='SLPostedCustomerTran'
WHERE       ([SLPostedCustomerTran].[SYSTraderTranTypeID]=4 OR [SLPostedCustomerTran].[SYSTraderTranTypeID]=5)
AND         [SLPostedCustomerTran].[SalControlValueInBaseCurrency] <> 0
GROUP BY    
    CASE 
    WHEN (SELECT TOP 1 [SiconCFMSetting].[SettingValue] FROM [SiconCFMSetting] WHERE [SiconCFMSetting].[SettingName]='UseAverageTimeToPay') = 'True'
    THEN ISNULL([SiconCFMForecastDate].[ForecastDate],DATEADD([DD],[SiconCFMSLCustomerAverageTimeToPayView].[Days],[SLPostedCustomerTran].[TransactionDate]))
    ELSE ISNULL([SiconCFMForecastDate].[ForecastDate],[SLPostedCustomerTran].[DueDate])
    END

无法在用于group by子句的group by列表的表达式中使用聚合或子查询。

在外部查询中进行聚合。你可以这样做

with cte as
(
SELECT
(
    SELECT CASE 
    WHEN (SELECT TOP 1 [SiconCFMSetting].[SettingValue] FROM [SiconCFMSetting] WHERE [SiconCFMSetting].[SettingName]='UseAverageTimeToPay') = 'True'
    THEN ISNULL([SiconCFMForecastDate].[ForecastDate],DATEADD([DD],[SiconCFMSLCustomerAverageTimeToPayView].[Days],[SLPostedCustomerTran].[TransactionDate]))
    ELSE ISNULL([SiconCFMForecastDate].[ForecastDate],[SLPostedCustomerTran].[DueDate])
    END
) AS [DueDate],
[SLPostedCustomerTran].[SalControlValueInBaseCurrency] AS [Value]
FROM        [SLPostedCustomerTran]
INNER JOIN  [SLCustomerAccount]
ON          [SLCustomerAccount].[SLCustomerAccountID]
=           [SLPostedCustomerTran].[SLCustomerAccountID]
INNER JOIN  [SiconCFMSLCustomerAverageTimeToPayView]
ON          [SiconCFMSLCustomerAverageTimeToPayView].[SLCustomerAccountID]

LEFT JOIN   [SiconCFMForecastDate]

AND         [SLPostedCustomerTran].[SalControlValueInBaseCurrency] <> 0

select DueDate,sum(Value)
from cte 
group by DueDate

谢谢，我现在就试一试！这就是诀窍！，我会尽快接受答案me@WraithNath检查另一种方式谢谢，我用一个外部选择做了一些测试，你用的语句和这两个都是非常相似的计时。外部应用会更快吗？是什么让你也这么想的？
