How can MySQL import an external database?

You can import an external database using either MySQL’s command line tool or its graphical interface tool.

The steps to import an external database using a command-line tool are as follows:

1. Open the command line tool and navigate to the “bin” folder within the installation directory of MySQL.
2. Enter the following command to import an external database into MySQL:

mysql -u 用户名 -p 数据库名 < 外部数据库文件路径

The username is the connection username for MySQL, the database name is the name of the database to be imported, and the external database file path is the file path of the external database.

1. Enter the password and press the Enter key to execute the command.

The steps to import an external database using a graphic interface tool are as follows:

1. Open the graphical interface tool and connect to the MySQL database server.
2. Look for the option to import into the database, usually found in the tools menu or toolbar.
3. Click on the “Import Database” option, choose the path to the external database file, and configure the relevant options such as character set and import method.
4. Click on the “Start” or “Import” button to begin importing the external database.

The importing process of an external database, whether through command line or graphical interface tools, may take some time depending on the size of the external database and the performance of the server.
