SQL查詢SUM（）和GROUP BY表中的2列

Question

我正在使用Microsoft Sql Server管理工作室。

我爲創建特定類型發票的稅務報表而混雜成功。

我有低於6％的金額，其他金額低於13.5％，最後金額有6％和13.5％的完整總額。

我在結果中得到了我的答案，但顯示了每個發票的兩個不同的行。一個是6％的值，另一個是13.5％的值。

我需要以某種方式將這兩行合併到每個發票的單一行中。

我的SQL查詢如下：

SELECT tran_no , 
     tran_date , 
     (SELECT SUM(edetail_amt) 
      WHERE  edetail_taxid = '6008U_=' 
     ) AS '6% amt' , 
     (SELECT SUM(edetail_per) 
      WHERE  edetail_taxid = '6008U_=' 
     ) AS '6% vat' , 
     (SELECT SUM(edetail_amt) 
      WHERE  edetail_taxid = '6008U_>' 
     ) AS '13.5% amt' , 
     (SELECT SUM(edetail_per) 
      WHERE  edetail_taxid = '6008U_>' 
     ) AS '13.5% vat' , 
     (SELECT SUM(edetail_amt + edetail_per) 
      WHERE  edetail_taxid IN ('6008U_=', '6008U_>') 
     ) AS 'Net Total' 
FROM h_edetail 
     INNER JOIN h_tran ON edetail_tranid = tran_kid 
WHERE tran_trantype = 'PI' 
     AND tran_date = '2016-11-03 00:00:00.000' 
GROUP BY tran_no , 
     tran_date , 
     edetail_taxid 
ORDER BY tran_no; 

與結果一起查詢的截圖如下：

如果我沒看錯你正在尋找這個

SELECT tran_no, 
     tran_date, 
     Sum(case when edetail_taxid = '6008U_=' then edetail_amt else 0 end) AS '6% amt', 
     Sum(case when edetail_taxid = '6008U_=' then edetail_per else 0 end) AS '6% vat', 
     Sum(case when edetail_taxid = '6008U_>' then edetail_amt else 0 end) AS '13.5% amt', 
     Sum(case when edetail_taxid = '6008U_>' then edetail_per else 0 end) AS '13.5% vat', 
     Sum(case when edetail_taxid IN ('6008U_=', '6008U_>') then edetail_amt + edetail_per else 0 end) AS 'Net Total' 
FROM h_edetail 
     INNER JOIN h_tran 
       ON edetail_tranid = tran_kid 
WHERE tran_trantype = 'PI' 
     AND tran_date = '2016-11-03 00:00:00.000' 
GROUP BY tran_no, 
      tran_date 
ORDER BY tran_no 

因爲select sum(edetail_amt) where edetail_taxid='6008U_='你被迫添加edetail_taxid在group by這是重複記錄的原因。你可以通過添加case內SUM總
