MySQL command line to export the database:
1. Go to the bin folder under the MySQL Directory: directory from cd MySQL to the bin folder
For example, if the command line I entered is cd C: \ Program Files \ MySQL Server 4.1 \ bin
(Or directly add the directory to the path of the windows environment variable)
2. Export Database: mysqldump-u username-p Database Name> exported file name
For example, the command line I entered is mysqldump-u root-p jluibmclub> d: \ jluibmclub. SQL (after entering the command, you will be asked to enter the MySQL password)
(If you export a single table, enter the table name after the database name)
During database backup using commands, enter C:/mysql/bin> mysqldump-uroot-p jluibmclub> d: \ jluibmclub. SQL In the cmd command box;

The reason is simple. Just remember one thing. If you do not enter the mysql environment, the SQL statement is not executed. The Hong Kong server and the Hong Kong virtual host do not need to be followed by a comma (";").
If you enter the mysql environment mysql>, the entered statement is an SQL statement. You must add a comma (";") at the end of the statement.
3. The file news. SQL is automatically generated under drive D. If the drive letter is not specified, it is in the bin directory by default.
Command Line import database:
1. Enter MySQL: mysql-u username-p
For example, the command line I entered is mysql-u root-p (enter the same password for MySQL)
2. Create the database you want to create in MySQL-Front. An empty database is used, for example, create a target database named "news ".
3. Enter the mysql> use target database name.
For example, the command line I entered is mysql> use news;
4. Import file: the file name imported from mysql> source;
For example, the command line I entered is mysql> source news. SQL (if a relative path name is used in the bin directory and an absolute directory name is used in other directories );
