第 2 行中的语法错误 (1064)

Question

我正在尝试将查询的表保存到另一个表中。我的新表已经使用以下结构创建：

TABLE: edit_mdr
+---------------+----------------+---------------------------------+
|Column         | Type           | Comment                         |
+---------------+----------------+---------------------------------+
| ID            | int(10)        | unsigned zerofill Auto Increment|
+---------------+----------------+---------------------------------+
| date_submitted| date           |                                 |
+---------------+----------------+---------------------------------+
| requestor     | varchar(40)    |                                 |
+---------------+----------------+---------------------------------+
| campus        | varchar(10)    |                                 | 
+---------------+----------------+---------------------------------+
| defect_loc    | varchar(40)    |                                 |
+---------------+----------------+---------------------------------+
| defect_des    | varchar(1500)  |                                 |
+---------------+----------------+---------------------------------+
| priority      | varchar(10)    |                                 |
+---------------+----------------+---------------------------------+
| action_taken  | varchar(1500)  |                                 |
+---------------+----------------+---------------------------------+
| assigned_to   | varchar(40)    |                                 |
+---------------+----------------+---------------------------------+
| category      | varchar(30)    |                                 |
+---------------+----------------+---------------------------------+
| photo         | varchar(200)   |                                 |
+---------------+----------------+---------------------------------+
| status        | varchar(10)    |                                 |
+---------------+----------------+---------------------------------+

查询如下：

MySQL Query:
INSERT INTO edit_mdr (date_submitted, requestor, campus, defect_loc, defect_des, priority, action_taken, assigned_to, category, photo, status) 
    VALUES(SELECT submit_time,
    MAX(IF(field_name = 'your-name',     field_value, NULL)) AS requestor,
    MAX(IF(field_name = 'menu-campus',   field_value, NULL)) AS campus,
    MAX(IF(field_name = 'location',      field_value, NULL)) AS defect_loc,
    MAX(IF(field_name = 'your-message',  field_value, NULL)) AS defect_des,
    MAX(IF(field_name = 'menu-priority', field_value, NULL)) AS priority,
    MAX(IF(field_name = 'work_done',     field_value, NULL)) AS action_taken,
    MAX(IF(field_name = 'assigned-to',   field_value, NULL)) AS assigned_to,
    MAX(IF(field_name = 'category',      field_value, NULL)) AS category,
    MAX(IF(field_name = 'file-photo',    field_value, NULL)) AS photo,
    MAX(IF(field_name = 'status',        field_value, NULL)) AS status
FROM
    wpc5_cf7dbplugin_submits
GROUP BY
    submit_time);

返回的错误是

查询中的错误 (1064)：'SELECT submit_time, 附近的语法错误， MAX(IF(field_name = 'your-name', field_value, NULL)' 在第 2 行

我不知道第二行所谓的错误是怎么回事......请帮忙！

INSERT INTO edit_mdr (date_submitted, requestor, campus, defect_loc, defect_des, priority, action_taken, assigned_to, category, photo, status) 

      SELECT submit_time,
    MAX(IF(field_name = 'your-name',     field_value, NULL)) AS requestor,
    MAX(IF(field_name = 'menu-campus',   field_value, NULL)) AS campus,
    MAX(IF(field_name = 'location',      field_value, NULL)) AS defect_loc,
    MAX(IF(field_name = 'your-message',  field_value, NULL)) AS defect_des,
    MAX(IF(field_name = 'menu-priority', field_value, NULL)) AS priority,
    MAX(IF(field_name = 'work_done',     field_value, NULL)) AS action_taken,

GROUP BY
    submit_time
;

尽量避免'VALUES'

INSERT INTO edit_mdr (date_submitted, requestor, campus, defect_loc, defect_des, priority, action_taken, assigned_to, category, photo, status) 
    (SELECT submit_time,
    MAX(IF(field_name = 'your-name',     field_value, NULL)) AS requestor,
    MAX(IF(field_name = 'menu-campus',   field_value, NULL)) AS campus,
    MAX(IF(field_name = 'location',      field_value, NULL)) AS defect_loc,
    MAX(IF(field_name = 'your-message',  field_value, NULL)) AS defect_des,
    MAX(IF(field_name = 'menu-priority', field_value, NULL)) AS priority,
    MAX(IF(field_name = 'work_done',     field_value, NULL)) AS action_taken,
    MAX(IF(field_name = 'assigned-to',   field_value, NULL)) AS assigned_to,
    MAX(IF(field_name = 'category',      field_value, NULL)) AS category,
    MAX(IF(field_name = 'file-photo',    field_value, NULL)) AS photo,
    MAX(IF(field_name = 'status',        field_value, NULL)) AS status
FROM
    wpc5_cf7dbplugin_submits
GROUP BY
    submit_time);
