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。


当前回答

只需使用下面的命令,

出口:

mysqldump -u [user] -p [db_name] | gzip > [filename_to_compress.sql.gz] 

进口:

gunzip < [compressed_filename.sql.gz]  | mysql -u [user] -p[password] [databasename] 

注意:关键字“-p”和密码之间没有空格。

其他回答

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。

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

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
