Question

我在SQL Server 2008中创建了两个表，如：

CompletedRecordsFinal：

IF OBJECT_Id('tempdb..#CompletedRecordsFinal') IS NOT NULL 
   DROP TABLE #CompletedRecordsFinal

SELECT
    C1, C2, C3, COUNT(distinct Id) as TotalRecords
INTO
    #CompletedRecordsFinal
FROM
    #CompletedRecords
GROUP BY  
    C1, C2, C3

示例结果：

C1  C2  C3  TotalRecords    
A   B   1       50          
A   B   2       100

WaitRecordsFinal：

IF OBJECT_Id('tempdb..#WaitRecordsFinal') IS NOT NULL 
   DROP TABLE #WaitRecordsFinal

SELECT 
    C1, C2, C3, COUNT(distinct Id) as TotalWaitRecords
INTO
    #WaitRecordsFinal
FROM
    #WaitRecords
GROUP BY
    C1, C2, C3

示例结果：

C1  C2  C3  TotalWaitRecords    
A   B   1       20  
A   B   2       30

我将这些表与左外连接一起使用，如：

SELECT
    w.C1, C.C2, w.C3, TotalWaitRecords, TotalRecords
FROM
    #WaitingRecordsFinal w  
LEFT OUTER JOIN 
    #CompletedRecordsFinal c ON c.C1 = w.C1 
                             AND c.C2 = w.C2 
                             AND c.C3 = w.C3

我想要的是在底部添加一行，我无法管理它。我觉得我很亲密，但没有像我现在想的那样工作。我需要类似的东西（它不起作用）：

SELECT 
    w.C1, C.C2, w.C3, TotalWaitRecords, TotalRecords
FROM
    #WaitingRecordsFinal w  
LEFT OUTER JOIN
    #CompletedRecordsFinal c ON c.C1 = w.C1 
                             AND c.C2 = w.C2 
                             AND c.C3 = w.C3 
UNION

SELECT
    C1 = 'Total', C2 = 'Total', C3 = -1, TotalWaitRecords, TotalRecords
FROM
    #WaitingRecordsFinal w  
LEFT OUTER JOIN
    #CompletedRecordsFinal c ON c.C1 = w.C1 
                             AND c.C2 = w.C2 
                             AND c.C3 = w.C3

我想要的输出示例：

   C1   C2   C3  TotalRecords   TotalWaitRecords    
    A   B     1     50              20  
    A   B     2     100             30
Total Total  -1     150             50

任何帮助都将不胜感激。

编辑：我的问题与指示为重复主题的问题略有不同。主要问题是我有3列用于分组。因此，当我group by C1, C2, C3, with rollup时，我看到了：

.....
X   B       -1  300 500
X   Total   -1  300 500
.....
A   B       -1  56  47
A   Total   -1  56  47
Total   Total   -1  356 547

我只需要最底线，而不是其他。所以这个解决方案没有帮助。我怎样才能摆脱除最底层总数之外的其他人？

Answer 1

您可以使用WITH ROLLUP并使用GROUPING（）标记总计。

Select CASE WHEN GROUPING(w.C1) = 1 THEN 'Total' ELSE w.c1
, CASE WHEN GROUPING(C.C2) = 1 THEN 'Total' ELSE c.c2
, CASE WHEN GROUPING(w.C3) = 1 THEN 'Total' ELSE w.c3
, SUM(TotalWaitRecords) AS TotalWaitRecords
, SUM(TotalRecords) AS TotalRecords
from #WaitingRecordsFinal w  
left outer join #CompletedRecordsFinal c 
on c.C1 = w.C1 
and c.C2 = w.C2 
and c.C3 = w.C3 

GROUP BY 
w.C1
, C.C2
, w.C3
with rollup

Answer 2

您可以尝试使用UNION ALL。我尝试使用CTE将您的2个查询合并为一个..

WITH cte AS 
(
    SELECT  wrf.C1,
            wrf.C2,
            wrf.C3,
            crf.TotalRecords,
            SUM(wrf.TotalWaitRecords) AS TotalWaitRecords
    FROM    (SELECT C1,
                    C2,
                    C3,
                    COUNT(DISTINCT Id) AS TotalWaitRecords
             FROM   #WaitRecords
             GROUP BY C1,
                    C2,
                    C3
            ) wrf
            OUTER APPLY (SELECT crf.C1,
                                crf.C2,
                                crf.C3,
                                SUM(TotalRecords) AS TotalRecords
                         FROM   (SELECT C1,
                                        C2,
                                        C3,
                                        COUNT(DISTINCT Id) AS TotalRecords
                                 FROM   #CompletedRecords
                                 GROUP BY C1,
                                        C2,
                                        C3
                                ) crf
                         WHERE  crf.C1 = wrf.C1
                                AND crf.C2 = wrf.C2
                                AND crf.C3 = wrf.C3
                         GROUP BY crf.C1,
                                crf.C2,
                                crf.C3
                        ) crf
    GROUP BY wrf.C1,
            wrf.C2,
            wrf.C3,
            crf.TotalRecords
)
SELECT  *
FROM    cte
UNION ALL
SELECT  'Total',
        'Total',
        -1,
        SUM(TotalRecords) TotalRecords,
        SUM(TotalWaitRecords) TotalWaitRecords
FROM    cte

SQL Fiddle Demo

如果我只使用你正在创建的临时表，你应该可以简单地这样做。

IF OBJECT_Id('tempdb..#AllRecordsFinal') IS NOT NULL 
   DROP TABLE #AllRecordsFinal

SELECT  wrf.C1,wrf.C2,wrf.C3,crf.TotalRecords,wrf.TotalWaitRecords 
INTO    #AllRecordsFinal
FROM    #WaitRecordsFinal wrf
OUTER APPLY (
        SELECT  TotalRecords
        FROM    #CompletedRecordsFinal cr
        WHERE   cr.C1 = wrf.C1 AND cr.C2 = wrf.C2 AND cr.C3 = wrf.C3) crf


SELECT  * FROM #AllRecordsFinal
UNION ALL 
SELECT  'Total','Total',-1,
        SUM(TotalRecords),
        SUM(TotalWaitRecords)
FROM    #AllRecordsFinal

在SQL Server查询的底部添加总行
