Type the following command to import sql data file:
输入以下命令导入sql数据文件：
$ mysql -u username -p -h localhost DATA-BASE-NAME < data.sql
In this example, import 'data.sql' file into 'blog' database using vivek as username:
在此示例中，使用 vivek 作为用户名将“data.sql”文件导入“blog”数据库：
$ mysql -u vivek -p -h localhost blog < data.sql
If you have a dedicated database server, replace localhost hostname with with actual server name or IP address as follows:
如果您有专用的数据库服务器，请将 localhost 主机名替换为实际的服务器名称或 IP 地址，如下所示：
$ mysql -u username -p -h 202.54.1.10 databasename < data.sql
To export a database, use the following:
要导出数据库，请使用以下命令：
mysqldump -u username -p databasename > filename.sql
Note the <and >symbols in each case.
请注意每种情况下的<和>符号。

If you're already running the SQL shell, you can use the sourcecommand to import data:
如果您已经在运行 SQL shell，则可以使用以下source命令导入数据：
use databasename;
source data.sql;

mysqldump will not dump database events, triggers and routines unless explicitly stated when dumping individual databases;
除非在转储单个数据库时明确说明，否则 mysqldump 不会转储数据库事件、触发器和例程；
mysqldump -uuser -p db_name --events --triggers --routines > db_name.sql
回答by Umesh Patil
Well you can use below command to export,
那么你可以使用下面的命令导出，
mysqldump --database --user=root --password your_db_name > export_into_db.sql
mysqldump --database --user=root --password your_db_name > export_into_db.sql
and the generated file will be available in the same directory where you had ran this command.
生成的文件将在您运行此命令的同一目录中可用。
Now login to mysql using command,
现在使用命令登录到mysql，
mysql -u[username] -p
mysql -u[用户名] -p
then use "source" command with the file path.
然后将“source”命令与文件路径一起使用。
