MySQL : How to restore single database from MySQL database dump backup

mysql -u root -p

drop user 'mysqlbackup'@'localhost';
drop user 'mysqlbackup'@'%';

GRANT SELECT, SHOW VIEW, RELOAD, REPLICATION CLIENT, EVENT, TRIGGER ON *.* TO 'mysqlbackup'@'localhost';
GRANT LOCK TABLES ON *.* TO 'mysqlbackup'@'localhost';
GRANT ALL PRIVILEGES ON *.* TO 'mysqlbackup'@'localhost';

mysql_config_editor print --all
mysql_config_editor remove --login-path=emultiskills_MYSQL_mysqlbackup

mysql_config_editor set --login-path=emultiskills_MYSQL_mysqlbackup --host=localhost --user=mysqlbackup --password

-- It prompts for the password.

table_schema "Database Name",
ROUND(SUM( data_length + index_length ) / 1024 / 1024, 2) AS "Database Size in MB"
FROM
information_schema.TABLES
GROUP BY table_schema ;
