Question

如何按行列分组数据？

查询：

SELECT *
FROM
(
    SELECT MONTH(T1.SPL_CreateDate) AS DateMonth,
           T1.SPL_EngagementCount,
           T1.SPL_ViewCount
    FROM LP_SocialPostLog T1
) T2
GROUP BY T2.DateMonth, SPL_EngagementCount, SPL_ViewCount

结果：

DateMonth   SPL_EngagementCount SPL_ViewCount
1            0                   1
1            1                   0
2            0                   1

我想要结果：

DateMonth   SPL_EngagementCount SPL_ViewCount
1            1                   1
2            0                   1

Answer 1

如果您使用SUM，则可以汇总其他两列

  SELECT DateMonth, 
         sum(SPL_EngagementCount) SPL_EngagementCount, 
         sum(SPL_ViewCount) SPL_ViewCount
    FROM (SELECT MONTH(T1.SPL_CreateDate) AS DateMonth, 
                 T1.SPL_EngagementCount, 
                 T1.SPL_ViewCount 
            FROM LP_SocialPostLog T1
         ) T2
GROUP BY T2.DateMonth

Answer 2

也许这个：

SELECT Month(SPL_CreateDate)    AS [DateMonth],
       Sum(SPL_EngagementCount) AS [SPL_EngagementCount],
       Sum(SPL_ViewCount)       AS [SPL_ViewCount]
FROM   LP_SocialPostLog
GROUP  BY Month(SPL_CreateDate)

注意：如果您想要最大值，请使用max()代替sum()。

Answer 3

我想你只想要这个？

SELECT MONTH(T1.SPL_CreateDate) AS DateMonth
  ,SUM(T1.SPL_EngagementCount) as SPL_EngagementCount
  ,SUM(T1.SPL_ViewCount) as SPL_ViewCount
FROM LP_SocialPostLog T1
GROUP BY MONTH(T1.SPL_CreateDate)
