Question

我的SQL知识非常基础，所以这可能是一个非常简单的解决方案，当我运行查询时，其中一列中有重复的服务/项目保证金＆＃39;，如何删除重复项（请记住，我希望仍然显示其他栏目中的数字＆＃39;产品保证金（如果可能的话，还可以加在一起）

这里是SQL： - 细节

    SELECT  DISTINCT
    [dbo].[v_api_find_Invoice].[Company_Name] AS 'Company'
   ,[dbo].[v_api_find_Invoice].[Invoice_Number] AS 'id'
   ,SUM(
   ([dbo].[v_rpt_Product].[Quantity] * [dbo].[v_rpt_Product].[unit_price]) -   
   ([dbo].[v_rpt_Product].[Quantity] * [dbo].[v_rpt_Product].[unit_cost])
       ) AS 'Product Margin'
   ,SUM([dbo].[v_rpt_Invoices].[Time_Amount] - 
        [dbo].[v_rpt_Invoices].[Progress_Amount_Applied]
       )  AS 'Service/Project Margin'
   ,[dbo].[v_api_find_Invoice].[DateInvoice] AS 'Date Invoice'
    FROM [dbo].[v_api_find_Invoice] WITH(NOLOCK) 
    LEFT OUTER JOIN [dbo].[v_rpt_Product] WITH(NOLOCK)  
      ON [dbo].[v_rpt_Product].[billing_log_recid] = 
         [dbo].[v_api_find_Invoice].[Billing_Log_RecID]
    LEFT OUTER JOIN [dbo].[v_rpt_Invoices] WITH(NOLOCK)  
      ON [dbo].[v_rpt_Invoices].[Billing_Log_RecID] = 
         [dbo].[v_api_find_Invoice].[Billing_Log_RecID]
    GROUP BY [dbo].[v_api_find_Invoice].[Invoice_Number]
            ,[dbo].[v_api_find_Invoice].[DateInvoice]
            ,[dbo].[v_api_find_Invoice].[Company_Name]
            ,[dbo].[v_rpt_Invoices].[Time_Amount] - 
             [dbo].[v_rpt_Invoices].[Progress_Amount_Applied]

编辑：这里有一些示例结果，您可以看到重复项更好（重复6000.00的列是服务/项目保证金：

80613公司X 11.65 6000.00 2014-12-30

80613公司X 36.80 6000.00 2014-12-30

80613公司X 48.55 6000.00 2014-12-30

Answer 1

从GROUP BY

中删除此表达式

dbo.v_rpt_Invoices.Time_Amount - dbo.v_rpt_Invoices.Progress_Amount_Applied

我希望你能让我用别名来清理那里的很多噪音：

SELECT
      fi.Company_Name AS Company
    , fi.Invoice_Number AS id
    , SUM(rp.Quantity * (rp.unit_price - rp.unit_cost)) AS "Product Margin"
    , SUM(ri.Time_Amount - ri.Progress_Amount_Applied) AS "Service/Project Margin"
    , fi.DateInvoice AS "Date Invoice"
FROM
    dbo.v_api_find_Invoice WITH (NOLOCK) as fi
    LEFT OUTER JOIN dbo.v_rpt_Product WITH (NOLOCK) as rp
        ON rp.billing_log_recid = fi.Billing_Log_RecID
    LEFT OUTER JOIN dbo.v_rpt_Invoices WITH (NOLOCK) as ri
        ON ri.Billing_Log_RecID = fi.Billing_Log_RecID
GROUP BY
      fi.Company_Name
    , fi.Invoice_Number
    , fi.DateInvoice

Answer 2

将“服务/项目保证金”列添加到GROUP BY子句中。
