集團通過和ORDER BY與UNION ALL

Question

我有以下查詢存儲過程：

SELECT (sum(addition)) AS [COUNT], 
MAX(CONVERT(VARCHAR(12),CREATED,102)) as [date] 
FROM [TABLE_ONE] 
WHERE convert(VARCHAR(12),CREATED,102) BETWEEN CONVERT(date,@startdate) AND CONVERT(date,@enddate) 
AND [ServiceID]=@serid 
GROUP BY CONVERT(VARCHAR(12),CREATED,102) 
ORDER BY CONVERT(VARCHAR(12),CREATED,102) 

我需要做一個union all，所以我可以從兩個表得到結果的總和，但，和我想要按照相同的方式對結果進行分組和排序。

這不起作用：

SELECT (sum(addition)) AS [COUNT], 
MAX(CONVERT(VARCHAR(12),CREATED,102)) as [date] 
FROM [TABLE_ONE] 
WHERE convert(VARCHAR(12),CREATED,102) BETWEEN CONVERT(date,@startdate) AND CONVERT(date,@enddate) 
AND [ServiceID]=@serid 
GROUP BY CONVERT(VARCHAR(12),CREATED,102) 
ORDER BY CONVERT(VARCHAR(12),CREATED,102) 

UNION ALL 

SELECT (sum(addition)) AS [COUNT], 
MAX(CONVERT(VARCHAR(12),CREATED,102)) as [date] 
FROM [TABLE_TWO] 
WHERE convert(VARCHAR(12),CREATED,102) BETWEEN CONVERT(date,@startdate) AND CONVERT(date,@enddate) 
AND [ServiceID]=@serid 
GROUP BY CONVERT(VARCHAR(12),CREATED,102) 
ORDER BY CONVERT(VARCHAR(12),CREATED,102) 

我要訂購的總體結果，並通過日化集團的。

您可以在union all後應用group by和order by：

SELECT (SUM(addition)) AS [COUNT], MAX([date]) AS [max_date] 
FROM (SELECT addition, CONVERT(VARCHAR(12),CREATED,102)) as [date] 
     FROM [TABLE_ONE] 
     WHERE CONVERT(VARCHAR(12),CREATED,102) 
        BETWEEN CONVERT(date,@startdate) AND 
          CONVERT(date,@enddate) 
       AND [ServiceID]=@serid 
     UNION ALL 
     SELECT addition, (CONVERT(VARCHAR(12),CREATED,102)) as [date] 
     FROM [TABLE_TWO] 
     WHERE CONVERT(VARCHAR(12),CREATED,102) 
        BETWEEN CONVERT(date,@startdate) AND 
          CONVERT(date,@enddate) 
       AND [ServiceID]=@serid) t 
GROUP BY [date] 
ORDER BY 2
