MySQL命令行下導出/入數據

1.登錄Linux

2.登錄MySQL：mysql -h192.168.1.1 -uroot  -p123123 【h-服務器IP，u-用戶名，p-密碼】

3.use mysqldemo; 【切換到表數據所在庫】

4.1導出數據：select * from TABLE into outfile '/var/lib/mysql-files/DEMO.SQL' fields terminated by ","; 【把TABLE查詢的結果輸出到/var/lib/mysql-files/DEMO.SQL；fields terminated by ","已逗號分隔，方便后面導入，也可以不加分隔】

　　①路徑/var/lib/mysql-files/是因為若不指定則會報錯：ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv option so it cannot execute this statement，

　　　　show variables like '%secure%';  【其他目錄對MySQL的權限限制，只能輸出到默認】

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

4.2導入數據：load data infile '/var/lib/mysql-files/DEMO.SQL' into table TABLE fields terminated by ",";【如果不加分隔符會導致多列插入第一列】
