mySQL::insert into table，来自另一个表的数据？

INSERT INTO action_2_members (campaign_id, mobile, vote, vote_date)  
SELECT campaign_id, from_number, received_msg, date_received
  FROM `received_txts`
 WHERE `campaign_id` = '8'

整行

insert into xyz select * from xyz2 where id="1";

对于选定的列

insert into xyz(t_id,v_id,f_name) select t_id,v_id,f_name from xyz2 where id="1";

zerkms 的回答是正确的方法。但是，如果有人希望在表中插入更多额外的列，那么您可以从以下获取它：

INSERT INTO action_2_members (`campaign_id`, `mobile`, `email`, `vote`, `vote_date`, `current_time`)
SELECT `campaign_id`, `from_number`, 'example@domain.xyz', `received_msg`, `date_received`, 1502309889 FROM `received_txts` WHERE `campaign_id` = '8'

在上面的查询中，有 2 个额外的列名为 email 和 current_time。

INSERT INTO Table1 SELECT * FROM Table2

INSERT INTO preliminary_image (style_id,pre_image_status,file_extension,reviewer_id,
uploader_id,is_deleted,last_updated) 

SELECT '4827499',pre_image_status,file_extension,reviewer_id,
uploader_id,'0',last_updated FROM preliminary_image WHERE style_id=4827488

分析

如果我们想将数据从一个表复制到mysql中的另一个表，我们可以使用上面的查询

这里源表和目标表相同，我们也可以使用不同的表。我们没有像 style_id 和 is_deleted 那样复制的几列，所以我们从另一个表中硬编码选择了它们 我们在源代码中使用的表也包含自动增量字段，所以我们离开了该列，它在执行查询时自动插入。

执行结果

执行了 1 个查询，1 个成功，0 个错误，0 个警告

查询：插入到primary_image (style_id,pre_image_status,file_extension,reviewer_id,uploader_id,is_deleted,last_updated) select ...

5 行受影响

此查询用于使用外键将数据从一个表添加到另一个表

let qry = "INSERT INTO `tb_customer_master` (`My_Referral_Code`, `City_Id`, `Cust_Name`, `Reg_Date_Time`, `Mobile_Number`, `Email_Id`, `Gender`, `Cust_Age`, `Profile_Image`, `Token`, `App_Type`, `Refer_By_Referral_Code`, `Status`) values ('" + randomstring.generate(7) + "', '" + req.body.City_Id + "', '" + req.body.Cust_Name + "', '" + req.body.Reg_Date_Time + "','" + req.body.Mobile_Number + "','" + req.body.Email_Id + "','" + req.body.Gender + "','" + req.body.Cust_Age + "','" + req.body.Profile_Image + "','" + req.body.Token + "','" + req.body.App_Type + "','" + req.body.Refer_By_Referral_Code + "','" + req.body.Status + "')";
                        connection.query(qry, (err, rows) => {
                            if (err) { res.send(err) } else {
                                let insert = "INSERT INTO `tb_customer_and_transaction_master` (`Cust_Id`)values ('" + rows.insertId + "')";
                                connection.query(insert, (err) => {
                                    if (err) {
                                        res.json(err)
                                    } else {
                                        res.json("Customer added")
                                    }
                                })
                            }
    
    
                        })
                    }
                }
    
            }
        })
    })
