如何根據不同條件進行分組

Question

我有以下表1，我希望將一組中的潛在客戶總金額分組。 然而，在Won階段，所有錢都處於贏得狀態的團隊面臨困難。

我想結果如下圖所示：

SELECT 
name,sum(value),stagename 
    FROM table1 
    group by name,stagename 

Answer 1

我想你想聚集在status和stagename列的組合：

select name, 
     (case when status = 'won' then 'won' else stagename end) as stagename, 
     sum(value) 
from table1 
group by name, 
     (case when status = 'won' then 'won' else stagename end); 

Answer 2

你可以像這樣的查詢：

select name, stagename, sum(value) from #yourstages 
    where status = 'open' 
    group by name, stagename 

union all 

select name, status as StageName, sum(value) from #yourstages 
    where status = 'won' 
    group by name, status 

Answer 3

對於多藝名值：

SELECT T1.name, CASE WHEN T1.STAGENAME=T2.STATUS THEN SUM(T2.VALUE) ELSE SUM(T1.value) END AS VALUE, T1.STAGENAME 
    FROM table1 T1 LEFT JOIN TABLE1 T2 ON T2.STATUS=T1.STAGENAME 
    group by T1.name,T2.STATUS, T1.stagename
