Question

SELECT distinct t1.vssyspackageid,CA.rAmount as Amount,Curr.vsShortCode AS Currency       


 from tblPrograms         
   INNER JOIN tblProgramsAndPackages ON tblPrograms.vsSysProgramId = tblProgramsAndPackages.vsSysProgramId         
   inner join tblPackages t1 on tblProgramsAndPackages.iPackageId=t1.iPackageId        
  right join tblPkgContractAwardDetails as CA on CA.iPackageId=t1.iPackageId  
   join tblCurrencies as Curr on CA.iCurrency =Curr.iCurrencyId    


   where tblPrograms.vsSysProgramId='JICA'        
  group by t1.vssyspackageid,CA.rAmount,Curr.vsShortCode

如果哪个包分配给承包商奖明细则，那么它将显示在一列中。

示例：GWSSP / 01，GWSSP / 02之后它显示下一列中的总包。

我不确定你想要什么，因为你的问题有点模糊，但我猜你想要一个指定Package的行，它将显示Amount列的总和。无论如何，这是我能从你的问题中理解的！

SELECT DISTINCT t1.vssyspackageid, 
                SUM(CA.rAmount) AS TotalAmount,
                Curr.vsShortCode AS Currency       
FROM            tblPrograms         
INNER JOIN      tblProgramsAndPackages ON tblPrograms.vsSysProgramId = 
                                          tblProgramsAndPackages.vsSysProgramId         
INNER JOIN      tblPackages AS t1 ON tblProgramsAndPackages.iPackageId = 
                                     t1.iPackageId        
RIGHT JOIN      tblPkgContractAwardDetails AS CA ON CA.iPackageId = 
                                                    t1.iPackageId  
JOIN            tblCurrencies AS Curr ON CA.iCurrency = 
                                         Curr.iCurrencyId    
WHERE           tblPrograms.vsSysProgramId = 'JICA' 
     AND        t1.[YOUR_COLUMN_NAME_HERE] = 'GWSSP/01'
GROUP BY        t1.vssyspackageid,
                Curr.vsShortCode

只需注意几点：

1. 我不知道tblPackages表中的列名称，例如'GWSSP / 01'所属的值，所以我留给你填写。
2. 如果您的软件包有多种货币，您仍会获得多行，如果是这种情况，则必须从Select和Group By子句中删除Curr.vsShortCode。
3. 我的代码也因为它非常混乱而难以理解，以及使用多种标准和捷径！
