您需要使用来定义FK约束

假设

user\u individual

references

profile\u individual

您的语句应该如下所示

创建表（如果不存在）`user\u individual`(
`first_name`varchar（100）不为空，
`姓氏'varchar（100）不为空，
`电子邮件地址'varchar（100）不为空，
`电话'varchar（100）不为空，
`用户名'varchar（100）不为空，
`密码'varchar（100）不为空，
`profile_id`varchar（250）不为NULL，-<您必须有一个FK列
主键（`email\u address`），
约束外键fk\u profile\u id（`profile\u id`）
REFERENCES profile\u individual（`profile\u id`）-<必须定义引用PK的FK约束
)ENGINE=MyISAM默认字符集=1；

这里是演示。

您试图在

（profile\u id）

上添加索引（

键）

），但表中没有这样的列（

profile\u id

）！与问题无关，但数据库中没有外键。您有一些索引，但根本没有外键。你需要InnoDB引擎，MyISAM有这么多外键。非常感谢…：）我错过了…：/不能使用MyISAM表定义FK约束。
