我需要这方面的帮助，我需要将 SQL 语法转换为 MS Access 语法，但我不知道如何。

INSERT INTO SampleData2
    SELECT 
        Object_Account, Descriptions, GL_Date, Document_Type, 
        Document_Number, Company, Subledger, Subledger_Type, ' ', 
        SUM(Actual_Amount * -1) AS TotalAmount, 
        (JE_Explantion) AS Explanation 
    FROM 
        SampleData
    WHERE 
        CAST(Object_Account AS VARCHAR(20)) + Subledger + JE_Explantion 
           IN (SELECT CAST(Object_Account AS VARCHAR(20)) + Subledger +  JE_Explantion 
               FROM SampleData 
               GROUP BY Object_Account, Subledger, JE_Explantion 
               HAVING COUNT(Object_Account) > 1)
    GROUP BY 
        Object_Account, Descriptions, GL_Date, Document_Type, 
        Document_Number, Company, Subledger, Subledger_Type, Remarks, 
        JE_Explantion

【问题讨论】：

我在您的代码中看不到任何供应商特定的部分...
请更具体地说明您尝试了什么以及什么不起作用。
是你使用CAST()的问题吗？

【解决方案1】：

MS Access 使用 & 进行字符串连接，不支持 cast()。你可以试试：

INSERT INTO SampleData2
    SELECT Object_Account, Descriptions, GL_Date, Document_Type, Document_Number,
           Company, Subledger, Subledger_Type, ' ', Sum(Actual_Amount * -1) AS TotalAmount, (JE_Explantion) As Explanation
    FROM SampleData as sd
    WHERE EXISTS (SELECT 1
                  FROM SampleData as sd2
                  WHERE sd2.Object_Account = sd.Object_Account AND
                        sd2.Subledger = sd.Subledger AND
                        sd2.JE_Explantion = sd.JE_Explantion
                  GROUP BY Object_Account, Subledger, JE_Explantion 
                  HAVING COUNT(Object_Account) > 1
                 )
    GROUP BY Object_Account, Descriptions, GL_Date, Document_Type, Document_Number, 
Company, Subledger, Subledger_Type, Remarks, JE_Explantion;
