GROUP BY與聚合SQL Server

Question

我有一個複雜的查詢，我已經轉儲到臨時表中。

在這個數據集中，我有不同類型的交易：電影，COD，功能，其他。

所有的交易，是COD和其他，並有一個totalrev_YTD BETWEEN 10K和15K應彙總成一個單一的行，交易名稱爲「總COD」 其他方面，它應該有它自己的路線。

我該怎麼做。我似乎無法使用SUM(totalrev_YTD)在10和15k之間執行GROUP BY。

任何人都可以請幫助：

SELECT 
    location, locationid, dealtype, 
    (CASE 
     WHEN dealtype = 'OTHER (COD, ETC)' and totalrev_YTD BETWEEN 10000 AND 15000 
      THEN 'OTHER (COD, ETC)' 
     ELSE deal 
    END) as deal, 
    rental_PW, rental_MTD, rental_QTD, rental_YTD, 
    sales_PW, sales_MTD, sales_QTD, sales_YTD, 
    otherrev_PW, otherrev_MTD, otherrev_QTD, otherrev_YTD, 
    totalrev_PW, totalrev_MTD, totalrev_QTD, totalrev_YTD 
FROM 
    #temp_rev t1 
WHERE 
    dealtype = 'OTHER (COD, ETC)' 
GROUP BY 
    (CASE 
     WHEN dealtype = 'OTHER (COD, ETC)' and totalrev_YTD BETWEEN 10000 AND 15000 
      THEN 'OTHER (COD, ETC)' 
     ELSE deal 
    END), 
    location, locationid, dealtype, 
    rental_PW, rental_MTD, rental_QTD, rental_YTD, 
    sales_PW, sales_MTD, sales_QTD, sales_YTD, 
    otherrev_PW, otherrev_MTD, otherrev_QTD, otherrev_YTD, 
    totalrev_PW, totalrev_MTD, totalrev_QTD, totalrev_YTD 

這方面的一個例子是，我有10個COD，其他交易。其中1筆交易的交易價格爲totalrev_YTD> 15K。在這種情況下，它應該與自己的行一起出現，另一個應該被聚合。

我認爲你的GROUP BY是好的，你只需要它在較少的列上，然後你彙總（與SUM）應該是，所有數字，總結。

在它是「單行」交易的情況下，查詢只會求和一行，這完全沒問題。

例子：

SELECT location, locationid, dealtype 
, (CASE WHEN dealtype = 'OTHER (COD, ETC)' and totalrev_YTD BETWEEN 10000 AND 15000 THEN 'OTHER (COD, ETC)' 
    ELSE deal 
    END 
) as deal, 
sum(rental_PW) as rental_PW, 
sum(rental_MTD) as rental_MTD, 
..., -- insert other summed columns here 
sum(totalrev_YTD) as totalrev_YTD 

FROM #temp_rev t1 
WHERE dealtype ='OTHER (COD, ETC)' 

GROUP BY 
(CASE WHEN dealtype = 'OTHER (COD, ETC)' and totalrev_YTD BETWEEN 10000 AND 15000 THEN 'OTHER (COD, ETC)' 
    ELSE deal 
    END 
) , 
location, locationid, dealtype
