Mysql 插入到两个表之间未重置自动增量

我有这个剧本：

#create departments table
CREATE TABLE `departments` (
  `department_id` int(11) NOT NULL AUTO_INCREMENT,
  `department_name` varchar(45) DEFAULT NULL,
  PRIMARY KEY (`department_id`)
) ENGINE=InnoDB AUTO_INCREMENT=10 DEFAULT CHARSET=utf8;

#inserts - departments table
INSERT INTO `departments`(`department_name`)VALUES("Parks and recreation");
INSERT INTO `departments`(`department_name`)VALUES("Portable immediate treatment");
INSERT INTO `departments`(`department_name`)VALUES("Veterinary");
INSERT INTO `departments`(`department_name`)VALUES("Gardening");
INSERT INTO `departments`(`department_name`)VALUES("Business Registration");
INSERT INTO `departments`(`department_name`)VALUES("Environment");
INSERT INTO `departments`(`department_name`)VALUES("Sanitation");
INSERT INTO `departments`(`department_name`)VALUES("Recycling");
INSERT INTO `departments`(`department_name`)VALUES("all");

#create departments_in_langueage table
CREATE TABLE `departments_in_language` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `department_id` int(11) DEFAULT NULL,
  `language` varchar(45) DEFAULT NULL,
  `description` varchar(45) DEFAULT NULL,
  PRIMARY KEY (`id`),
  KEY `departments_in_language_department_id_idx` (`department_id`),
  CONSTRAINT `departments_in_language_department_id` FOREIGN KEY (`department_id`) REFERENCES `departments` (`department_id`) ON DELETE NO ACTION ON UPDATE NO ACTION
) ENGINE=InnoDB AUTO_INCREMENT=9 DEFAULT CHARSET=utf8;

#inserts - departments_in_language table
INSERT INTO `departments_in_language`(`department_id`,`language`,`description`)VALUES("1","hebrew","חזות העיר");
INSERT INTO `departments_in_language`(`department_id`,`language`,`description`)VALUES("2","hebrew","ניידת טיפול מיידי");
INSERT INTO `departments_in_language`(`department_id`,`language`,`description`)VALUES("3","hebrew","ווטרינריה");
INSERT INTO `departments_in_language`(`department_id`,`language`,`description`)VALUES("4","hebrew","גינון");
INSERT INTO `departments_in_language`(`department_id`,`language`,`description`)VALUES("5","hebrew","רישוי עסקים");
INSERT INTO `departments_in_language`(`department_id`,`language`,`description`)VALUES("6","hebrew","איכות הסביבה");
INSERT INTO `departments_in_language`(`department_id`,`language`,`description`)VALUES("7","hebrew","תברואה");
INSERT INTO `departments_in_language`(`department_id`,`language`,`description`)VALUES("8","hebrew","מיחזור");
INSERT INTO `departments_in_language`(`department_id`,`language`,`description`)VALUES("9","hebrew","כללי");

语言中的部门具有名为=“部门id”（外键）的字段。 问题是： 运行此脚本时，出现了一些错误：

Cannot add or update a child row: a foreign key constraint fails (`teres`.`departments_in_language`, CONSTRAINT `departments_in_language_department_id` FOREIGN KEY (`department_id`) REFERENCES `departments` (`department_id`) ON DELETE NO ACTION ON UPDATE NO )

我看到部门的Id不是从1开始的， 这意味着插入之间的“自动”计数器未复位； 这就是错误的原因。

我能做什么？

您的表创建查询将

自动增量设置为10和9。它应该设置为1

#create departments table
CREATE TABLE `departments` (
  [...]
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

#create departments_in_langueage table
CREATE TABLE `departments_in_language` (
  [...]
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

#create departments table
CREATE TABLE `departments` (
  [...]
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

#create departments_in_langueage table
CREATE TABLE `departments_in_language` (
  [...]
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

在第一个表中，
AUTO INCREMENT
设置为10，您试图将
department\u id
插入为1,2,3,4。。。首先，请尝试将
AUTO INCREMENT
设置为1是，我知道，但我想重置AUTO…如果您希望简单地重置AUTO INCREMENT，只需提醒您的表
ALTER table table name AUTO_INCREMENT=1
可以，但我不建议您这样做否，但是，既然已经存在具有相同ID的数据，您为什么要再次重置它呢？这可能会导致其他问题。在第一个表中，

声明。当我在创建表后没有插入时，我需要更改自动字段吗？请参见我的编辑，我错过了表创建中的
