如何将同一张表的两个不同计数结合在一起？

Question

我正在处理的表格是某些问题的答案记录。我想找出人们对470,477,479,481,483问题中提供者23的肯定，肯定的百分比。所以我试图计算答案的总数和'是的，肯定'的答案。我可以分开做，但不能在一张桌子上加入。

一个查询是获取表SurveyAnswerFact中记录的总数。

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 

结果：

470 44 
477 40 
479 43 
481 43 
483 44 

另一个查询获得是 '是的，绝对是'

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 

结果答案的计数：

470 43 
477 39 
479 35 
481 42 
483 39 

我试图用SQL将它们连接在一起，但是结果与第一个查询的结果相同。我的预期结果是这样的：

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

任何人都可以教我正确的方式加入他们？

Answer 1

也许你的意思是......

我所做的就是消除其中的响应条款，并把它添加到被选择和组。

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基于新的信息---------

有几个方法可以做到这一点。使用案例声明

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 

另一种方法是按照您的建议加入表格，但这会产生更多开销。 （这使用了公共表为每个查询，使加盟更易于阅读。）

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
