GROUP BY与聚合SQL Server

Question

我有一个复杂的查询，我已经转储到临时表中。

在这个数据集中，我有不同类型的交易：电影，COD，功能，其他。

所有的交易，是COD和其他，并有一个totalrev_YTD BETWEEN 10K和15K应汇总成一个单一的行，交易名称为“总COD” 其他方面，它应该有它自己的路线。

我该怎么做。我似乎无法使用SUM(totalrev_YTD)在10和15k之间执行GROUP BY。

任何人都可以请帮助：

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 

这方面的一个例子是，我有10个COD，其他交易。其中1笔交易的交易价格为totalrev_YTD> 15K。在这种情况下，它应该与自己的行一起出现，另一个应该被聚合。

我认为你的GROUP BY是好的，你只需要它在较少的列上，然后你汇总（与SUM）应该是，所有数字，总结。

在它是“单行”交易的情况下，查询只会求和一行，这完全没问题。

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
