Question

使用mysql并尝试删除外部约束，但我无法删除该密钥。

SHOW CREATE TABLE xxxx;

它的节目，

CREATE TABLE `xxxx` (
 `id` int(11) NOT NULL AUTO_INCREMENT,
 `user_id` int(11) NOT NULL,
 `name` text NOT NULL,
 `article_title` text NOT NULL,
 `created_at` datetime NOT NULL,
 `last_modified_at` datetime NOT NULL,
 `latest_version` tinyint(4) NOT NULL,
 `status` tinyint(4) NOT NULL,
 `is_deleted` enum('0','1') NOT NULL,
 `deleted_time` datetime NOT NULL,
 `manual_authorgroup_data` text NOT NULL,
 PRIMARY KEY (`id`),
 KEY `user_id` (`user_id`),
 CONSTRAINT `fk_users_xxxx_user_id` FOREIGN KEY (`user_id`) REFERENCES `users` (`user_id`) ON DELETE CASCADE ON UPDATE CASCADE
) ENGINE=InnoDB AUTO_INCREMENT=19 DEFAULT CHARSET=latin1

如何解决此问题，请帮助我。
