Question

嗨，我是mysql的新手，我可以成功插入一行，但是我想插入三行，但是我一直在花很多时间思考，如果有人可以提供建议或帮助我，我将非常感谢您

INSERT INTO earning (id, dateCreated,
dateModified,
x_t_name,
x_start_date,
x_end_month,
x_address,x_category,x_pic,x_promo_space,x_start_month,x_space_query,x_organizer,x_end_date 
,x_address_query,x_current_pic,x_start_year
,x_end_year
,x_event_title
,x_pix_name),

SELECT x_add1,dateCreated,dateModified,"","2018-11-01",
x_end_month,"address1","",x_current_pic,"",x_start_month,"''","", "2018-11-12","'address1'"
,x_current_pic,x_end_year,x_end_year,"",""
  FROM Sale
 WHERE id = 'x1'

但是随后我想在多行中插入我要分配不同的ID和地址

我尝试过这样，但是我知道它错了

INSERT INTO earning (id, dateCreated,
dateModified,
x_t_name,
x_start_date,
x_end_month,
x_address,x_category,x_pic,x_promo_space,x_start_month,x_space_query,x_organizer,x_end_date 
,x_address_query,x_current_pic,x_start_year
,x_end_year
,x_event_title
,x_pix_name),

(id, dateCreated,
dateModified,
x_t_name,
x_start_date,
x_end_month,
x_address,x_category,x_pic,x_promo_space,x_start_month,x_space_query,x_organizer,x_end_date 
,x_address_query,x_current_pic,x_start_year
,x_end_year
,x_event_title
,x_pix_name),

(id, dateCreated,
dateModified,
x_t_name,
x_start_date,
x_end_month,
x_address,x_category,x_pic,x_promo_space,x_start_month,x_space_query,x_organizer,x_end_date 
,x_address_query,x_current_pic,x_start_year
,x_end_year
,x_event_title
,x_pix_name)

SELECT x_add1,dateCreated,dateModified,"","2018-11-01",
x_end_month,"address1","",x_current_pic,"",x_start_month,"''","", "2018-11-12","'address1'"
,x_current_pic,x_end_year,x_end_year,"",""
  FROM Sale
 WHERE id = 'x1'


    SELECT x_add2,dateCreated,dateModified,"","2018-11-01",
x_end_month,"address2","",x_current_pic,"",x_start_month,"''","", "2018-11-12","'address2'"
,x_current_pic,x_end_year,x_end_year,"",""
  FROM Sale
 WHERE id = 'x1'


    SELECT x_add13,dateCreated,dateModified,"","2018-11-01",
x_end_month,"address3","",x_current_pic,"",x_start_month,"''","", "2018-11-12","'address3'"
,x_current_pic,x_end_year,x_end_year,"",""
  FROM Sale
 WHERE id = 'x1'

Answer 1

要插入多行，请使用以下语法：

//Check if courses_enrolled_module_id is set $courses_enrolled_module_id = $this->request->getQuery('courses_enrolled_module_id'); //If so make sure it is valid if($courses_enrolled_module_id){ $this->loadModel('CoursesEnrolledModules'); $coursesEnrolledModule = $this->CoursesEnrolledModules->get($courses_enrolled_module_id, ['contain'=>[], ]); //Pass variable to view so we can show correct back button $this->set('coursesEnrolledModule', $coursesEnrolledModule); //Also after save we will redirect. }

Answer 2

正确的语法是

INSERT INTO table2 (column1, column2, column3, ...)
SELECT column1, column2, column3, ...
FROM table1
WHERE condition;

您可以尝试在where子句中添加另一个语句，如下所示

WHERE id = 'x1' and x_address IN (address1, address2, address3)

Answer 3

您可以在UNION查询中使用SELECT插入所有值。请注意，UNION的默认行为是删除重复的行，因此，如果要将它们放在表中，则需要将UNION更改为UNION ALL。

INSERT INTO earning (id, dateCreated,
dateModified,
x_t_name,
x_start_date,
x_end_month,
x_address,x_category,x_pic,x_promo_space,x_start_month,x_space_query,x_organizer,x_end_date 
,x_address_query,x_current_pic,x_start_year
,x_end_year
,x_event_title
,x_pix_name)
SELECT x_add1,dateCreated,dateModified,"","2018-11-01",
x_end_month,"address1","",x_current_pic,"",x_start_month,"''","", "2018-11-12","'address1'"
,x_current_pic,x_end_year,x_end_year,"",""
  FROM Sale
 WHERE id = 'x1'
UNION
    SELECT x_add2,dateCreated,dateModified,"","2018-11-01",
x_end_month,"address2","",x_current_pic,"",x_start_month,"''","", "2018-11-12","'address2'"
,x_current_pic,x_end_year,x_end_year,"",""
  FROM Sale
 WHERE id = 'x1'
UNION
    SELECT x_add13,dateCreated,dateModified,"","2018-11-01",
x_end_month,"address3","",x_current_pic,"",x_start_month,"''","", "2018-11-12","'address3'"
,x_current_pic,x_end_year,x_end_year,"",""
  FROM Sale
 WHERE id = 'x1'

插入选择多行
