  array.reduce((objectsByKeyValue, obj) => {
    const value = obj[key];
    objectsByKeyValue[value] = (objectsByKeyValue[value] || []).concat(obj);
    return objectsByKeyValue;

	PRIMARY KEY (`iso2`)
	) ENGINE=InnoDB DEFAULT CHARSET=utf8;

	INSERT INTO `country` (`iso2`, `name`, `iso3`, `numeric`) VALUES
	('AF', 'Afghanistan', 'AFG', 4),
