Database schema for a password reset functionality.

gistfile1.sql

CREATE TABLE IF NOT EXISTS `resetpasswordtokens` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `userID` int(11) NOT NULL,
  `token` char(32) NOT NULL,
  `status` set('used','new') NOT NULL DEFAULT 'new',
  `date` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY (`id`),
  KEY `userID` (`userID`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

What's the work of Status here?

CREATE TABLE IF NOT EXISTS `resetpasswordtokens` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `userID` int(11) NOT NULL,
  `token` char(32) NOT NULL,
  `consumed` boolean DEFAULT 0,
  `expired` boolean DEFAULT 0,
  `expirationDate` timestamp NULL,
  PRIMARY KEY (`id`),
  KEY `userID` (`userID`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 AUTO_INCREMENT=1 ;
