创建表 MySql 时出错 - (errno: 150)答案

【问题标题】：Error with creating tables MySql - (errno: 150)创建表 MySql 时出错 - (errno: 150)
【发布时间】：2015-02-20 12:01:25
【问题描述】：

我对这个脚本有疑问。有人可以帮我吗？

ERROR 1005: Can't create table 'db_new.users_roles' (errno: 150)
SQL Statement:
CREATE TABLE `luxury`.`users_roles` (
  `id` INT NOT NULL AUTO_INCREMENT,
  PRIMARY KEY (`id`))

在数据库中有“用户”和“角色”表。 "users_roles" 是 ManyToMany Hibernate 的表

【解决方案1】：

像这样尝试一次，

CREATE TABLE IF NOT EXISTS `users_roles` (
  `id` int(12) NOT NULL AUTO_INCREMENT,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

我删除了 sn-p 因为这不是 HTML。使用sqlfiddle。
ERROR 1005 (HY000): Can't create table 'luxury.users_roles' (errno: 150)
上面的代码很完美，但我不知道你为什么会出错，一旦阅读了这个问题-答案可能对你有用：stackoverflow.com/questions/16227199/mysql-errno-150

【解决方案2】：

不妨试试下面的

检查您对用户的所有权限。

select user,host from mysql.user;

查找授予特定 MySQL 帐户的权限：

show grants for 'root'@'%';

分析您的表格

analyze table luxury

优化

optimize table luxury

再次运行您的脚本
