如何將同一張表的兩個不同計數結合在一起？

Question

我正在處理的表格是某些問題的答案記錄。我想找出人們對470,477,479,481,483問題中提供者23的肯定，肯定的百分比。所以我試圖計算答案的總數和'是的，肯定'的答案。我可以分開做，但不能在一張桌子上加入。

一個查詢是獲取表SurveyAnswerFact中記錄的總數。

SELECT SurveyQuestionKey, count(1) 
FROM [WAREHOUSE].[dbo].[SurveyAnswerFact] 
WHERE ([ProviderKey] = 23) 
AND ([SurveyQuestionKey] IN (470,477,479,481,483))   
AND ([Response] = 'Yes, definitely') 
AND ([ResponseDateKey] BETWEEN 20140601 AND 20150531) 
GROUP BY SurveyQuestionKey 

結果：

470 44 
477 40 
479 43 
481 43 
483 44 

另一個查詢獲得是 '是的，絕對是'

SELECT SurveyQuestionKey, count(1) 
FROM [WAREHOUSE].[dbo].[SurveyAnswerFact] 
WHERE (ProviderKey = 23) 
AND (SurveyQuestionKey IN (470,477,479,481,483)) 
AND ([ResponseDateKey] BETWEEN 20140601 AND 20150531) 
GROUP BY SurveyQuestionKey 

結果答案的計數：

470 43 
477 39 
479 35 
481 42 
483 39 

我試圖用SQL將它們連接在一起，但是結果與第一個查詢的結果相同。我的預期結果是這樣的：

470 43 44 
477 39 40 
479 35 43 
481 42 43 
483 39 44 

任何人都可以教我正確的方式加入他們？

Answer 1

也許你的意思是......

我所做的就是消除其中的響應條款，並把它添加到被選擇和組。

SELECT SurveyQuestionKey, Response, count(1) 
    FROM [WAREHOUSE].[dbo].[SurveyAnswerFact] 
    WHERE ([ProviderKey] = 23) 
     AND ([SurveyQuestionKey] IN (470,477,479,481,483))   
     AND ([ResponseDateKey] BETWEEN 20140601 AND 20150531) 
    GROUP BY SurveyQuestionKey, Response 

-------------- UPDATE基於新的信息---------

有幾個方法可以做到這一點。使用案例聲明

SELECT SurveyQuestionKey, count(1) as Totalcount, sum(case when Response = 'Yes, definitely' then 1 else 0 end) as [Yes Def] 
FROM [WAREHOUSE].[dbo].[SurveyAnswerFact] 
WHERE ([ProviderKey] = 23) 
AND ([SurveyQuestionKey] IN (470,477,479,481,483))   
AND ([ResponseDateKey] BETWEEN 20140601 AND 20150531) 
GROUP BY SurveyQuestionKey 

另一種方法是按照您的建議加入表格，但這會產生更多開銷。 （這使用了公共表爲每個查詢，使加盟更易於閱讀。）

With totalCount as (SELECT SurveyQuestionKey, count(1) cnt 
FROM [WAREHOUSE].[dbo].[SurveyAnswerFact] 
WHERE ([ProviderKey] = 23) 
AND ([SurveyQuestionKey] IN (470,477,479,481,483))   
AND ([Response] = 'Yes, definitely') 
AND ([ResponseDateKey] BETWEEN 20140601 AND 20150531) 
GROUP BY SurveyQuestionKey), 

YesDefCount as (SELECT SurveyQuestionKey, count(1) cnt 
FROM [WAREHOUSE].[dbo].[SurveyAnswerFact] 
WHERE ([ProviderKey] = 23) 
AND ([SurveyQuestionKey] IN (470,477,479,481,483))   
AND ([ResponseDateKey] BETWEEN 20140601 AND 20150531) 
GROUP BY SurveyQuestionKey) 

SELECT surveyQuestionKey, totalcount.cnt, yesDefCount.count 
from totalcount A 
LEFT JOIN YESDEFCOUNT B 
on A.SurveyQuestionKey = B.SurveyQuestionKey; 

Answer 2

SELECT SurveyQuestionKey, count(1), x.totals 
    FROM [WAREHOUSE].[dbo].[SurveyAnswerFact], 
     (select count(1) totals from [WAREHOUSE].[dbo].[SurveyAnswerFact]) x 
WHERE ([ProviderKey] = 23) 
    AND ([SurveyQuestionKey] IN (470,477,479,481,483))   
    AND ([Response] = 'Yes, definitely') 
    AND ([ResponseDateKey] BETWEEN 20140601 AND 20150531) 
GROUP BY SurveyQuestionKey
