mysql - MySQL帮助转发工程

所以我试图将我在Workbench6.2上创建的数据库部署到一个真实的数据库（以测试它）。
但每次我部署它时都会不断地出现错误，每次我想我已经解决了这个问题，就会弹出一些其他的错误消息（这次是1064）。
有谁能帮我弄一下我的数据库，这样我就可以最终部署它并进行测试了吗？（我是个笨蛋，所以请对我耐心点）……
这正是Forward Engineering试图执行的：

最佳答案

edit 1064的意思是“语法错误”，如果你在运行由类似workbench的工具创建的sql时发现了这个问题，那就意味着这个工具有一个bug或者你用错了它。
当mysql检测到错误时，它会显示单词for the right syntax to use near，然后显示一些查询，从查询中第一个不理解的字符开始。这有助于你找出问题所在。
在你的问题中，这是一个右括号。对我来说，这意味着它希望在REFERENCES子句的括号之间出现一些东西。
在我看来，您的模型的administrators表有许多格式错误的外键返回到users表。
这里只有一个。

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

注意()：它引用的是表，但没有列。
