的Oracle SQL摘要/樞軸表

Question

我有一個數據組，看起來像這樣：

ID  Description      Team 
    A  Missing Name; Missing Gender Team1 
    B  Missing Gender     Team1 
    C  Missing Name     Team2 
    D  Missing Name     Team2 

即，每個ID具有一個線，以識別與該ID的任何問題文本列（介紹），以及作爲該ID所屬的團隊的名稱。我已經成功地概括它：

Team  Missing Gender  Missing Name 
    Team1  2     1 
    Team2  0     2 

通過使用一個case語句看起來像這樣：

 SELECT 
    "Team", 
    sum(case when "DQ Info" like '%Missing Gender%' then 1 ELSE 0 END) as "Missing Gender", 
    sum(case when "DQ Info" like '%Missing Name%' then 1 ELSE 0 END) as "Missing Name" 
    FROM 
    (*) 
    GROUP BY "Team" 

我希望能夠使它看起來像來概括這個數據這個代替：

Description   Team1  Team2 
    Missing Gender  2   0 
    Missing Name  1   2 

我知道一定有這樣做的一種方式，但我此刻的掙扎 - 在上述領域只使用「說明」，而不是「團隊」給出了這樣的結果：

Description      Team1  Team2 
    Missing Name; Missing Gender 1   0 
    Missing Gender     1   0 
    Missing Name     0   2 

這不是我所追求的。任何幫助表示讚賞，但我會繼續修改，所以如果我設法弄清楚，我會更新這篇文章。請注意，這僅僅是數據集的一個例子，而不是實際的數據集。

編輯：根據bpgergo的建議進行查詢。在完成一些閱讀後，看起來下面將會短路，即一旦滿足內部情況下的第一個標準就終止查詢，這意味着它將永遠不能夠多次計數列。這是一個恥辱，但我認爲我將不得不堅持我的原始查詢。

SELECT 
    "Description", 
    sum(case when "Team" like 'Team1' then 1 ELSE 0 END) as "Team1", 
    sum(case when "Team" like 'Team2' then 1 ELSE 0 END) as "Team2" 
    FROM(SELECT 
    "Team", 
    case when "DQ Info" like '%[Check Role]%' then '[Check Role]' 
    ELSE case when "DQ Info" like '%[Client deceased]%' then '[Client deceased]' 
    ELSE case when "DQ Info" like '%[2 Parents not recorded]%' then '[2 Parents not recorded]' 
    ELSE case when "DQ Info" like '%[Religion not recorded]%' then '[Religion not recorded]' 
    ELSE case when "DQ Info" like '%[1st Language not recorded]%' then '[1st Language not recorded]' 
    ELSE case when "DQ Info" like '%[Ethnicity not recorded]%' then '[Ethnicity not recorded]' 
    ELSE case when "DQ Info" like '%[No Current Worker]%' then '[No Current Worker]' 
    ELSE case when "DQ Info" like '%[No Current Team]%' then '[No Current Team]' 
    ELSE case when "DQ Info" like '%[Update Gender]%' then '[Update Gender]' 
    ELSE case when "DQ Info" like '%[No Plan]%' then '[No Plan]' 
    ELSE case when "DQ Info" like '%[Update Plan]%' then '[Update Plan]' 
    END END END END END END END END END END END 
    as "Description" 
    FROM(
    * 
    FROM 
    (*)WORKLOAD)DATA) 
    GROUP BY "Description"

你已經半途而廢了。嘗試這樣的事情作爲一個內部的選擇

select 
case when "Description" like '%Missing Gender%' then "Missing_gender" 
ELSE case when "Description" like '%Missing Name%' then "Missing_name" ELSE null END 
END as "Description", 
Team 
from your_table 

整個選擇會是這樣的

SELECT 
"Description", 
sum(case when "Team" = 'Team1' then 1 ELSE 0 END) as "Team1", 
sum(case when "Team" = 'Team2' then 1 ELSE 0 END) as "Team2", 
FROM 
(
    select 
    case when "Description" like '%Missing Gender%' then "Missing_gender" 
    ELSE case when "Description" like '%Missing Name%' then "Missing_name" ELSE null END 
    END as "Description", 
    Team 
    from your_table 
) 
GROUP BY "Description"
