Question

我已经尝试过检查类似的帖子但只是无法正确使用，请帮忙。

此查询返回正确的数据，但更新语句会抱怨，因为它不仅仅是

SELECT 
    classificationchartofaccountname, 
    -SUM(ISNULL(HLD.Nominal, 0))  AS 'Total' 
FROM
    [dbsFPM].[dbo].[rpt_Holdings] HLD 
INNER JOIN 
    [dbsFPM].[dbo].[rpt_FundAccounts] FA ON HLD.Username = FA.Username 
                                         AND HLD.ClientPortfolioCode = FA.ClientPortfolioCode 
                                         AND FA.ClassificationChartOfAccountName = HLD.InstrumentName 
WHERE 
    HLD.username =  @username 
    AND FA.Username = @username 
    AND FA.Narration = 'IncomeStatement' 
    AND FA.AccountType = 'Expense'  
GROUP BY 
    ClassificationChartOfAccountName)

返回值：

classificationchartofaccountname    Total

General Expenses on ZAR 17578.38

lc Audit 2014 on ZAR    6533.12

lc Trustee Fees - Other on ZAR  840.41

lc Trustee Fees-ZAR 38524.34

Management Fees-ZAR 6452680.040

Performance Fees-ZAR    175.80

更新语句我想按如下方式使用错误：

Msg 512，Level 16，State 1，Line 1
子查询返回的值超过1。这是不允许的子查询跟随=，！=，＆lt;，＆lt; =，＆gt;，＆gt; =或当子查询用作表达。

以下是更新：

UPDATE [rpt_FundAccounts]
SET ReconNarration = 'ExpenseAnalysis_Period', 
    Recon = (SELECT -SUM(ISNULL(HLD.Nominal, 0)) 
             FROM [dbo].[rpt_Holdings] HLD 
             INNER JOIN [dbo].[rpt_FundAccounts] FA ON HLD.Username = FA.Username 
                                                    AND HLD.ClientPortfolioCode = FA.ClientPortfolioCode 
                                                    AND FA.ClassificationChartOfAccountName = HLD.InstrumentName 
             WHERE HLD.username =  @Username 
               AND FA.Username = @Username 
               AND FA.Narration = 'IncomeStatement' 
               AND FA.AccountType = 'Expense' 
               /* and ClassificationChartOfAccountName = 'Management Fees-ZAR'*/ 
             GROUP BY ClassificationChartOfAccountName)
WHERE 
    username = @username  
    AND Narration = 'IncomeStatement' 
    AND AccountType = 'Expense' 
    /*and ClassificationChartOfAccountName = 'Management Fees-ZAR' */

问题是，我想更新所有ClassificationChartOfAccountNames及其各自的总计[rpt_Holdings]

请帮助，对不起，我还是初学者！

此处的问题出现在子查询中的GROUP BY语句中。它使得输出不是一个SUM值，而是每个ClassificationChartOfAccountName的带有SUM的表。但是您无法使用TABLE更新标量值，并且您收到错误 - Subquery returned more than 1 value

如果要根据行ClassificationChartOfAccountName更新包含SUM的表，则应在更新的表行和子查询之间建立链接。因此子查询只输出一个值。我认为它应该是这样的：

UPDATE [rpt_FundAccounts] FA 
SET ReconNarration = 'ExpenseAnalysis_Period', 
    Recon = (select -sum(isnull(HLD.Nominal,0)) 
             from [dbo].[rpt_Holdings] HLD 
             WHERE  HLD.Username =  FA.Username 
                    and HLD.ClientPortfolioCode = FA.ClientPortfolioCode 
                    and FA.ClassificationChartOfAccountName = HLD.InstrumentName
             )
WHERE username = @username  
      and Narration = 'IncomeStatement' 
      and AccountType = 'Expense'

SQL使用group by语句更新多个值不起作用
