MySQL 帮助正向工程

Question

所以我正在尝试将我在 workbench 6.2 上创建的数据库部署到真实数据库中（以对其进行测试）...

但我每次部署它时都会收到错误消息，每次我认为我已经解决了这个问题时，都会弹出一些其他错误消息（这次是 1064）..

任何人都可以帮我解决我的数据库问题，以便我最终可以部署它并进行测试吗？（我是菜鸟所以请耐心等待我）..

这就是正向工程试图执行的：

Edit 1064 仅表示 "syntax error." 如果您在尝试运行 SQL 由 Workbench，这意味着该工具有错误或您使用不正确。

当 MySQL 检测到错误时，它会输出单词 for the right syntax to use near 然后显示您的一些查询，从您查询中的第一个字符开始它没有明白了。那是为了帮助你找出你的问题可能出在哪里。

在您的问题中，这是一个右括号。这对我来说意味着它期望在 REFERENCES 子句中的括号之间出现某些内容。

在我看来，您模型的 administrators table 有很多格式错误的外键返回 users table。

这只是其中之一。

     CONSTRAINT `user_login`
        FOREIGN KEY ()
        REFERENCES `iPlanner`.`users` ()
        ON DELETE NO ACTION
        ON UPDATE NO ACTION,

注意 ()：它引用了 table 但没有列。
