SQL Server 2008查询 - 表连接

Question

我无法从SQL Server 2008查询中获取所需的结果。查询1为[GeneralErrors]生成我想要的结果，查询2为[RehabErrors]生成正确的结果，但我真的需要它们在同一行上。当我在查询3中尝试并结合这两个查询时，[GeneralErrors]的结果不正确，但是我要去查表的方式。

查询1：

SELECT 
     ReviewID, 
     SUM(CASE Score_CorrectID_Accuracy WHEN 'Error' THEN 1 ELSE 0 END + 
     CASE Score_ProperlyIdentified_Accuracy WHEN 'Error' THEN 1 ELSE 0 END) AS GeneralErrors 
    FROM 
     Reviews 
    WHERE 
     (UserID IS NOT NULL AND UserID <> '') 
    GROUP BY 
     Reviews.ReviewID 

Results: 

ReviewID GeneralErrors 
7   0 
8   0 
9   0 
10   0 
11   0 
12   9 
13   0 
14   0 
15   4 

问题2：

SELECT 
     Reviews.ReviewID 
     ,COUNT(RehabMetricsCalls.ReviewID) AS RehabErrors 
    FROM RehabMetrics INNER JOIN 
      RehabMetricsCalls ON RehabMetrics.RehabMetricID = RehabMetricsCalls.RehabMetricID RIGHT OUTER JOIN 
      Reviews ON RehabMetricsCalls.ReviewID = Reviews.ReviewID 
    WHERE 
     (UserID IS NOT NULL AND UserID <> '') 
    GROUP BY 
     Reviews.ReviewID 

Results: 

ReviewID RehabErrors 
7   3 
8   0 
9   0 
10   0 
11   0 
12   5 
13   5 
14   0 
15   4 

问题3： 我在两个查询相结合的尝试，其产生不正确的结果

SELECT DISTINCT 
     Reviews.ReviewID 
     ,SUM(CASE Score_CorrectID_Accuracy WHEN 'Error' THEN 1 ELSE 0 END + 
     CASE Score_ProperlyIdentified_Accuracy WHEN 'Error' THEN 1 ELSE 0 END + 
     CASE Score_MiniMiranda_Accuracy WHEN 'Error' THEN 1 ELSE 0 END + 
     CASE Score_Tone_Accuracy WHEN 'Error' THEN 1 ELSE 0 END + 
     CASE Score_Accuracy_Accuracy WHEN 'Error' THEN 1 ELSE 0 END + 
     CASE Score_Notepad_Accuracy WHEN 'Error' THEN 1 ELSE 0 END +   
     CASE Score_PCAResponsive_Accuracy WHEN 'Error' THEN 1 ELSE 0 END + 
     CASE Score_AWGInfo_Accuracy WHEN 'Error' THEN 1 ELSE 0 END + 
     CASE Complaint_Accuracy WHEN 'Error' THEN 1 ELSE 0 END) AS GeneralErrors 
     ,COUNT(RehabMetricsCalls.ReviewID) AS RehabErrors 
    FROM RehabMetrics INNER JOIN 
      RehabMetricsCalls ON RehabMetrics.RehabMetricID = RehabMetricsCalls.RehabMetricID INNER JOIN 
      Reviews ON RehabMetricsCalls.ReviewID = Reviews.ReviewID 
    WHERE 
     (UserID IS NOT NULL AND UserID <> '') 
    GROUP BY 
     Reviews.ReviewID 

期望的结果：

ReviewID GeneralErrors RehabErrors 
    7   0    3 
    12   45    5 
    13   0    5 
    15   16    4

做一个加盟..

;with Firstquery as 
(
SELECT 
ReviewID, 
SUM(CASE Score_CorrectID_Accuracy WHEN 'Error' THEN 1 ELSE 0 END + 
CASE Score_ProperlyIdentified_Accuracy WHEN 'Error' THEN 1 ELSE 0 END) AS GeneralErrors 
FROM 
Reviews 
WHERE 
(UserID IS NOT NULL AND UserID <> '') 
GROUP BY 
Reviews.ReviewID 
) 
,Secondquery as 
(
SELECT 
    Reviews.ReviewID 
,COUNT(RehabMetricsCalls.ReviewID) AS RehabErrors 
FROM RehabMetrics INNER JOIN 
    RehabMetricsCalls ON RehabMetrics.RehabMetricID = RehabMetricsCalls.RehabMetricID RIGHT OUTER JOIN 
Reviews ON RehabMetricsCalls.ReviewID = Reviews.ReviewID 
WHERE 
(UserID IS NOT NULL AND UserID <> '') 
GROUP BY 
    Reviews.ReviewID 
) 
select 
fs.reviewid,fs.generalerrors,sq.rehaberrors 
from 
firstquery fs 
join 
secondquery sq 
on fs.reviewid=sq.reviewid
