Oracle查詢得到列的和不同的價值觀

Question

我試圖讓特定列的總和

我想Oracle查詢得到的列「timespend」之和爲（S_1，S_4每個場景，S_5，S_8）其中名稱是等於b

name id scenario timespend 
A 123 S_1  2 
A 123 S_1  5 
A 123 S_3 6.3 
B 124 S_1 3 
B 124 S_1 8.9 
B 124 S_1 5 
B 124 S_1 4 
B 124 S_5 1.23 
B 124 S_5 56 
B 124 S_5 8 
B 124 S_8 9 
B 124 S_8 4 
C 125 S_8 6 
D 126 S_2 9 
D 126 s_4 5 
D 126 s_4 6.2 
D 126 s_4 7 
E 127 S_1 8 
E 127 S_1 1 

我已經使用下面的查詢，但其用柱timespend的總和返回

select sum(timespend), 
     scenario 
from table1 
where scenario in ('s_1','s_3','s_4','s_5','s_8') 
and name = 'B' 
group by scenario 

查詢的輸出是

sum(timespend) scenario 
-------------- -------- 
154.63   s_1 
154.63   s_5 
154.63   s_8 

預計產量

sum(timespend) scenario 
-------------- -------- 
20.9   s_1 
65.23   s_5 
19    s_8 

誰能幫助我獲得預期的輸出像上面提到的？

我沒有看到一個問題，你的查詢（儘管場景S_8您的預期輸出是錯誤的，再加上你的where子句中使用的情況下s以上）：

with table1 as (select 'A' name, 123 id, 'S_1' scenario, 2 timespend from dual union all 
       select 'A' name, 123 id, 'S_1' scenario, 5 timespend from dual union all 
       select 'A' name, 123 id, 'S_3' scenario, 6.3 timespend from dual union all 
       select 'B' name, 124 id, 'S_1' scenario, 3 timespend from dual union all 
       select 'B' name, 124 id, 'S_1' scenario, 8.9 timespend from dual union all 
       select 'B' name, 124 id, 'S_1' scenario, 5 timespend from dual union all 
       select 'B' name, 124 id, 'S_1' scenario, 4 timespend from dual union all 
       select 'B' name, 124 id, 'S_5' scenario, 1.23 timespend from dual union all 
       select 'B' name, 124 id, 'S_5' scenario, 56 timespend from dual union all 
       select 'B' name, 124 id, 'S_5' scenario, 8 timespend from dual union all 
       select 'B' name, 124 id, 'S_8' scenario, 9 timespend from dual union all 
       select 'B' name, 124 id, 'S_8' scenario, 4 timespend from dual union all 
       select 'C' name, 125 id, 'S_8' scenario, 6 timespend from dual union all 
       select 'D' name, 126 id, 'S_2' scenario, 9 timespend from dual union all 
       select 'D' name, 126 id, 'S_4' scenario, 5 timespend from dual union all 
       select 'D' name, 126 id, 'S_4' scenario, 6.2 timespend from dual union all 
       select 'D' name, 126 id, 'S_4' scenario, 7 timespend from dual union all 
       select 'E' name, 127 id, 'S_1' scenario, 8 timespend from dual union all 
       select 'E' name, 127 id, 'S_1' scenario, 1 from dual) 
-- end of mimicking your table1 with data in it. See SQL below: 
select sum(timespend), 
     scenario 
from table1 
where scenario in ('S_1','S_3','S_4','S_5','S_8') 
and name = 'B' 
group by scenario 
order by scenario; 

SUM(TIMESPEND) SCENARIO 
-------------- -------- 
      20.9 S_1  
     65.23 S_5  
      13 S_8 

也許，從事實判斷一些在您的樣本數據的場景數據的是小寫，你提到你要找的set of scenarios that look similar，你可能需要以下呢？

select sum(timespend), 
     upper(scenario) scenario 
from table1 
where upper(scenario) in ('S_1','S_3','S_4','S_5','S_8') 
and name = 'B' 
group by upper(scenario) 
order by upper(scenario);
