MySQL命令行下导出/入数据

1.登录Linux

2.登录MySQL：mysql -h192.168.1.1 -uroot  -p123123 【h-服务器IP，u-用户名，p-密码】

3.use mysqldemo; 【切换到表数据所在库】

4.1导出数据：select * from TABLE into outfile '/var/lib/mysql-files/DEMO.SQL' fields terminated by ","; 【把TABLE查询的结果输出到/var/lib/mysql-files/DEMO.SQL；fields terminated by ","已逗号分隔，方便后面导入，也可以不加分隔】

　　①路径/var/lib/mysql-files/是因为若不指定则会报错：ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv option so it cannot execute this statement，

　　　　show variables like '%secure%';  【其他目录对MySQL的权限限制，只能输出到默认】

+--------------------------+-----------------------+
| Variable_name            | Value                 |
+--------------------------+-----------------------+
| require_secure_transport | OFF                   |
| secure_auth              | ON                    |
| secure_file_priv         | /var/lib/mysql-files/ |
+--------------------------+-----------------------+

4.2导入数据：load data infile '/var/lib/mysql-files/DEMO.SQL' into table TABLE fields terminated by ",";【如果不加分隔符会导致多列插入第一列】
