mysql - 无法将表导入 MySQL

Question

在尝试将表导入数据库时​​，出现以下错误:

#1005 - Can't create table 'pyrea.#sql-16a4_67' (errno: 121) (Details...) 

当我尝试在 SQL 选项卡中导入此内容时，会发生这种情况:

CREATE TABLE IF NOT EXISTS `guild_wars` (
  `id` INT NOT NULL AUTO_INCREMENT,
  `guild_id` INT NOT NULL,
  `enemy_id` INT NOT NULL,
  `begin` BIGINT NOT NULL DEFAULT '0',
  `end` BIGINT NOT NULL DEFAULT '0',
  `frags` INT UNSIGNED NOT NULL DEFAULT '0',
  `payment` BIGINT UNSIGNED NOT NULL DEFAULT '0',
  `guild_kills` INT UNSIGNED NOT NULL DEFAULT '0',
  `enemy_kills` INT UNSIGNED NOT NULL DEFAULT '0',
  `status` TINYINT(1) UNSIGNED NOT NULL DEFAULT '0',
  PRIMARY KEY (`id`),
  KEY `status` (`status`),
  KEY `guild_id` (`guild_id`),
  KEY `enemy_id` (`enemy_id`)
) ENGINE=InnoDB;

ALTER TABLE `guild_wars`
  ADD CONSTRAINT `guild_wars_ibfk_1` FOREIGN KEY (`guild_id`) REFERENCES `guilds` (`id`) ON DELETE CASCADE,
  ADD CONSTRAINT `guild_wars_ibfk_2` FOREIGN KEY (`enemy_id`) REFERENCES `guilds` (`id`) ON DELETE CASCADE;

ALTER TABLE `guilds` ADD `balance` BIGINT UNSIGNED NOT NULL AFTER `motd`;

CREATE TABLE IF NOT EXISTS `guild_kills` (
  `id` INT NOT NULL AUTO_INCREMENT PRIMARY KEY,
  `guild_id` INT NOT NULL,
  `war_id` INT NOT NULL,
  `death_id` INT NOT NULL
) ENGINE = InnoDB;

ALTER TABLE `guild_kills`
  ADD CONSTRAINT `guild_kills_ibfk_1` FOREIGN KEY (`war_id`) REFERENCES `guild_wars` (`id`) ON DELETE CASCADE,
  ADD CONSTRAINT `guild_kills_ibfk_2` FOREIGN KEY (`death_id`) REFERENCES `player_deaths` (`id`) ON DELETE CASCADE,
  ADD CONSTRAINT `guild_kills_ibfk_3` FOREIGN KEY (`guild_id`) REFERENCES `guilds` (`id`) ON DELETE CASCADE;

ALTER TABLE `killers` ADD `war` INT NOT NULL DEFAULT 0;

有人知道这个吗？抱歉，我对此还很陌生。

尝试删除约束

CREATE TABLE IF NOT EXISTS `guild_wars` (
  `id` INT NOT NULL AUTO_INCREMENT,
  `guild_id` INT NOT NULL,
  `enemy_id` INT NOT NULL,
  `begin` BIGINT NOT NULL DEFAULT '0',
  `end` BIGINT NOT NULL DEFAULT '0',
  `frags` INT UNSIGNED NOT NULL DEFAULT '0',
  `payment` BIGINT UNSIGNED NOT NULL DEFAULT '0',
  `guild_kills` INT UNSIGNED NOT NULL DEFAULT '0',
  `enemy_kills` INT UNSIGNED NOT NULL DEFAULT '0',
  `status` TINYINT(1) UNSIGNED NOT NULL DEFAULT '0',
  PRIMARY KEY (`id`),
  KEY `status` (`status`),
  KEY `guild_id` (`guild_id`),
  KEY `enemy_id` (`enemy_id`)
) ENGINE=InnoDB;

CREATE TABLE IF NOT EXISTS `guild_kills` (

  `guild_id` INT NOT NULL,
  `war_id` INT NOT NULL,
  `death_id` INT NOT NULL
) ENGINE = InnoDB;
