你可以使用下面的命令，

Mysqldump——databases——user=root——password your_db_name > export_into_db.sql

生成的文件将在运行此命令的同一目录中可用。

你可以找到更多关于mysqldump的官方参考:Import Export MySQL DB

注意:使用——databases代替——database，因为不再支持最后一个。

享受:)

您可以使用此脚本从终端导出或导入任何数据库 网址:https://github.com/Ridhwanluthra/mysql_import_export_script/blob/master/mysql_import_export_script.sh

echo -e "Welcome to the import/export database utility\n"
echo -e "the default location of mysqldump file is: /opt/lampp/bin/mysqldump\n"
echo -e "the default location of mysql file is: /opt/lampp/bin/mysql\n"
read -p 'Would like you like to change the default location [y/n]: ' location_change
read -p "Please enter your username: " u_name
read -p 'Would you like to import or export a database: [import/export]: ' action
echo

mysqldump_location=/opt/lampp/bin/mysqldump
mysql_location=/opt/lampp/bin/mysql

if [ "$action" == "export" ]; then
    if [ "$location_change" == "y" ]; then
        read -p 'Give the location of mysqldump that you want to use: ' mysqldump_location
        echo
    else
        echo -e "Using default location of mysqldump\n"
    fi
    read -p 'Give the name of database in which you would like to export: ' db_name
    read -p 'Give the complete path of the .sql file in which you would like to export the database: ' sql_file
    $mysqldump_location -u $u_name -p $db_name > $sql_file
elif [ "$action" == "import" ]; then
    if [ "$location_change" == "y" ]; then
        read -p 'Give the location of mysql that you want to use: ' mysql_location
        echo
    else
        echo -e "Using default location of mysql\n"
    fi
    read -p 'Give the complete path of the .sql file you would like to import: ' sql_file
    read -p 'Give the name of database in which to import this file: ' db_name
    $mysql_location -u $u_name -p $db_name < $sql_file
else
    echo "please select a valid command"
fi

我用过wamp服务器。我试了试

c:\wamp\bin\mysql\mysql5.5.8\bin\mysqldump -uroot -p db_name > c:\somefolder\filename.sql

Root是我mysql的用户名，如果你有密码，请指定:

-p[yourpassword]

希望它有用。

我已经在D: drive安装了我的wamp服务器，所以你必须从ur命令行到以下路径->(如果你已经在c: drive安装了wamp，那么只需将D:替换为c: here)

D:\>cd wamp
D:\wamp>cd bin
D:\wamp\bin>cd mysql
D:\wamp\bin\mysql>cd mysql5.5.8 (whatever ur verserion will be displayed here use keyboard Tab button and select the currently working mysql version on your server if you have more than one mysql versions)
D:\wamp\bin\mysql\mysql5.5.8>cd bin
D:\wamp\bin\mysql\mysql5.5.8\bin>mysqldump -u root -p password db_name > "d:\backupfile.sql"

这里根是我的phpmyadmin的用户 密码是phpmyadmin的密码，所以如果你没有为root设置任何密码，在那个地方什么都没有， Db_name是数据库(为哪个数据库进行备份) , backupfile。SQL是你想要备份你的数据库的文件，你也可以改变备份文件的位置(d:\backupfile.sql)从任何其他地方在你的计算机

mysqldump --no-tablespaces -u username -p pass database_name > db_backup_file.sql

windows操作系统:

当你得到错误1064 mysql(42000)，而试图执行mysqldump命令，退出当前终端。执行mysqldump命令。

mysql>exit 
c:\xampp\mysql\bin>mysqldump -uroot -p --databases [database_name] > name_for_export_db.sql
