我收到了这个错误“错误：错误 1005：无法创建表（errno：150）”，我的所有表都对外键有约束。

在服务器中执行 SQL 脚本

我正在使用 MySQL Workbench，这是模型： http: //puu.sh/42CTd.png。

我正在尝试这样做，因为如果我删除用户，我不想丢失我的数据库中的任何条目。

如果您有其他解决方案，我已准备好尝试！

您已将author其作为主键的一部分，这意味着它不可为空，但您已获得ON DELETE SET NULL该字段的外键约束。这两个条件是不相容的。

要修复它，author请从您的PRIMARY KEY声明中删除；您的id_newsletter字段已经auto_increment是唯一的，除非您的应用程序专门设置它（在这种情况下您不应该使用auto_increment）。

验证引用的字段是否已编入索引并且是否具有兼容的数据类型是一个好主意；从提供的信息中我看不到这一点，但将其添加到您的“errno 150 清单”中是一件好事：）
