Question

我正在尝试运行以下查询，并将结果放入名为weekly_summary_activities的表中。

Select 
  email, campaign, type, 
  year, week, business_comp, 
  activity, SUM(hours) 
FROM activity_log 
Group By email, campaign, project,
  business_comp, activity

weekly_summary_activities的结构为

+--------+---------------+-------------+-------------------+------------+------+---------+----------+----------------+
|     #  |     Name      |    Type     |     Collation     | Attributes | Null | Default | Comments |     Extra      |
+--------+---------------+-------------+-------------------+------------+------+---------+----------+----------------+
|      1 | idPrimary     | tinyint(4)  |                   |            | No   | None    |          | AUTO_INCREMENT |
|      2 | email         | varchar(30) | latin1_swedish_ci |            | No   | None    |          |                |
|      3 | campaign      | varchar(30) | latin1_swedish_ci |            | No   | None    |          |                |
|      4 | type          | varchar(3)  | latin1_swedish_ci |            | No   | None    |          |                |
|      5 | year          | varchar(4)  | latin1_swedish_ci |            | No   | None    |          |                |
|      6 | week          | int(3)      |                   |            | No   | None    |          |                |
|      7 | business_comp | varchar(30) | latin1_swedish_ci |            | No   | None    |          |                |
|      8 | project       | varchar(30) | latin1_swedish_ci |            | No   | None    |          |                |
|      9 | activity      | varchar(30) | latin1_swedish_ci |            | No   | None    |          |                |
|     10 | hours         | int(8)      |                   |            | No   | None    |          |                |
+--------+---------------+-------------+-------------------+------------+------+---------+----------+----------------+

我尝试过：

INSERT INTO weekly_summary_activities 
SELECT email, 
       campaign, 
       type, 
       year, 
       week, 
       business_comp, 
       activity, 
       Sum(hours) 
FROM   activity_log 
GROUP  BY email, 
          campaign, 
          project, 
          business_comp, 
          activity

但出现错误“＃1136-列数与第1行的值数不匹配”。我究竟做错了什么？似乎只是插入不起作用。我可以在phpMyAdminSQL的SQL选项卡中运行查询（执行插入操作），这似乎可行。

您应在insert into子句中指定列，例如：

INSERT INTO weekly_summary_activities (email, campaign, type, year, week, business_comp, activity, hours)
SELECT email, campaign, type, year, week, business_comp, activity, SUM(hours) 
FROM activity_log
GROUP BY email, campaign, project, business_comp, activity

您遇到了问题，因为该表包含一个Id列。表具有比插入子句更多的列。

与Group By一起插入
