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 -h [host] -p -u [user] [database name] > filename.sql

localhost中的示例

mysqldump -h localhost -p -u root cookbook > cookbook.sql

所有这些解决方案(使用>重定向器字符)的问题是您从stdout写入转储，这可能会破坏数据库中某些字符的编码。

如果你有字符编码问题。例如:

错误1064(42000):你有一个错误的SQL语法;检查手册，对应于您的MySQL服务器版本的正确语法使用近…

然后，你必须使用-r选项来写入文件。

MySQL

mysqldump -u user -pyour-password-without-space-between-letter-p-and-your-password --default-character-set=utf8 --host $HOST database-name -r dump.sql

使用码头工人

docker exec --rm -v $pwd:dump -it mysql:5:7 mysqldump -u user -pyour-password-without-space-between-letter-p-and-your-password --default-character-set=utf8 --host $HOST database-name -r dump/dump.sql

注意:这会将当前路径挂载为实例中的转储。

我们在这里找到了答案

相反，不要使用<将转储文件导入数据库，同样，您的非utf8字符可能不会被传递;但更喜欢源选项。

mysql -u user -pYourPasswordYouNowKnowHow --default-character-set=utf8 your-database
mysql> SET names 'utf8'
mysql> SOURCE dump.sql

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

首先 打开命令提示符，然后在CMD中打开bin目录(我希望你知道CMD命令) 进入WAMP程序文件中MySql文件夹的bin目录。

运行命令

mysqldump -u db_username -p database_name > path_where_to_save_sql_file

按enter system将导出特定的数据库并创建SQL文件到给定的位置。

我希望你能做到。 如果你有任何问题，请告诉我。

在此路径下进入命令提示符，

C:\Program Files (x86)\MySQL\MySQL服务器5.0\bin>

然后输入以下命令导出数据库(-p后没有空格)

mysqldump -u[用户名]-p[用户名]你的数据库>[存档]wantedsqlfile.sql
