从SQL DUMP导入数据库模式

Question

我有以下数据库模式，有一堆表和外键，当我尝试导入SQL转储时，我不断收到以下错误。

Can't create table errno 150 

我明白，这是试图创建与尚未创建表的依赖关系表，但我不明白如何导入模式，而不屠杀了所有的外键，然后重新创建它们根据Stack和Google提供的答案。

必须有一个更简单的方法，大公司做什么有数百个表？

我有下面的SQL语句和任何建议，将不胜感激。谢谢

Answer 1

我发现我只需要两条线来解决我的问题，我在顶部添加了一个0，底部添加了一个，我很好。对不起，浪费你的时间......

SET FOREIGN_KEY_CHECKS = 0; 

SET FOREIGN_KEY_CHECKS = 1; 

Answer 2

最简单的方法是通过命令行来做到这一点是这样的：

mysql db_name < backup-file.sql 

这个执行你的SQL文件在一个事务中。如果你在一个事务中执行你的东西，那么你将不会得到外键错误。
