如何将csv文件导入到MySQL

如何将csv文件导入到MySQL？

将csv文件导入到MySQL

首先登录MySQL:

mysql -u root -p123456

创建数据表，保证字段和csv文件中的列一致

mysql> show DATABASES;
mysql> use TEST;
mysql> show TABLES;
mysql> CREATE TABLE mytable(
    -> id INT NOT NULL AUTO_INCREMENT,
    -> Qtime DATETIME NOT NULL,
    -> Tprice FLOAT NOT NULL,
    -> PRIMARY KEY ( id )
    -> )ENGINE=InnoDB DEFAULT CHARSET=utf8;

查看安全路径，也就是要将上传文件放到安全路径下，才能成功上传

mysql> show variables like '%secure%';
+--------------------------+-----------------------+
| Variable_name            | Value                 |
+--------------------------+-----------------------+
| require_secure_transport | OFF                   |
| secure_auth              | ON                    |
| secure_file_priv         | /var/lib/mysql-files/ |
+--------------------------+-----------------------+

在终端中复制文件到安全路径

sudo cp /home/hadoop/文档/文件.csv /var/lib/mysql-files

然后在到mysql下执行

mysql> load data infile '/var/lib/mysql-files/文件.csv'  into table mytable fields terminated by ',' optionally enclosed by '"' escaped by '"' lines terminated by '\n';

导出文件类似

mysql> select * from `table` load data infile '/文档/test.csv' fields terminated by ',' optionally enclosed by '"' escaped by '"' lines terminated by '\n';
