MySQL資料庫如何用命令列匯出帶表頭和不帶表頭的csv檔案

實驗如下:
建表：
mysql> CREATE TABLE `test` (
    ->   `id` varchar(64) NOT NULL,
    ->   `ecode` varchar(10) DEFAULT NULL,
    ->   `type` varchar(12) DEFAULT NULL,
    ->   `timeid` varchar(12) DEFAULT NULL,
    ->   `start_time` date DEFAULT NULL,
    ->   `end_time` varchar(12) DEFAULT NULL,
    ->   PRIMARY KEY (`id`),
    ->   KEY `start` (`start_time`),
    ->   KEY `end` (`end_time`)
    -> ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
Query OK, 0 rows affected (0.35 sec)


mysql>
mysql>
插入資料:
mysql> insert into test select * from date_rule;
Query OK, 1412 rows affected (0.49 sec)
Records: 1412  Duplicates: 0  Warnings: 0




不帶表頭:
mysql> select * from test into outfile 'd:\test.csv' fields terminated by ','enclosed by '"'lines terminated by '\r\n';
ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv option so it cannot execute this statement


匯出報錯，原因是5.7版本對mysqld 的匯入匯出做限制，解決辦法：
在my.ini中加上
[mysqld]
secure_file_priv=''
重啟資料庫使配置生效


PS C:\WINDOWS\system32> net stop mysql
MySQL 服務正在停止.
MySQL 服務已成功停止。


PS C:\WINDOWS\system32> net start mysql
MySQL 服務正在啟動 ..
MySQL 服務已經啟動成功。


再次執行命令成功:
mysql> select * from test into outfile "d:/test.csv" fields terminated by ','enclosed by '"'lines terminated by '\r\n';
Query OK, 1412 rows affected (0.00 sec)


用Notepad++開啟檔案發現沒表頭：

檢視錶結構:
mysql> desc test;
+------------+-------------+------+-----+---------+-------+
| Field      | Type        | Null | Key | Default | Extra |
+------------+-------------+------+-----+---------+-------+
| id         | varchar(64) | NO   | PRI | NULL    |       |
| ecode      | varchar(10) | YES  |     | NULL    |       |
| type       | varchar(12) | YES  |     | NULL    |       |
| timeid     | varchar(12) | YES  |     | NULL    |       |
| start_time | date        | YES  | MUL | NULL    |       |
| end_time   | varchar(12) | YES  | MUL | NULL    |       |
+------------+-------------+------+-----+---------+-------+
6 rows in set (0.00 sec)


帶表頭匯出csv:
mysql> select * from (select 'id','ecode','type','timeid','start_time','end_time' union all select id,ecode,type,timeid,start_time,end_time from test) b  into outfile "d:/test.csv" fields terminated by ','enclosed by '"'lines terminated by '\r\n';
Query OK, 1413 rows affected (0.01 sec)


用Notepad++開啟檔案發現帶表頭：
"id","ecode","type","timeid","start_time","end_time"
"00000c-month-20161","00000c","month","20161","2015-12-29","2016-01-28"
"00000c-month-201610","00000c","month","201610","2016-09-29","2016-10-28"
"00000c-month-201611","00000c","month","201611","2016-10-29","2016-11-28"
