我有一个相当大的数据库,所以我想用命令提示符导出它,但我不知道如何。

我正在使用WAMP。

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。

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

mysql -u -p databaseName>fileToPutDatabase . mysql

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。

我试图转储在docker上运行的db,并提出了以下命令来实现相同的目的:

Docker exec <container_id/name> /usr/bin/mysqldump -u <db_username>——password=<db_password> db_name > .sql

希望这能有所帮助!
