Answer 1

我怀疑你正在使用一些软件工具（SQL Workbench或其他一些东西）来做这个所谓的正向工程。通常的工作方式是该工具可以创建SQL，然后通过数据库连接将其传递给DBMS。

您的工具正在生成有缺陷的SQL数据定义语言（DDL）代码。这不好。是时候停止信任该工具了。

@Michael Berkowski诊断出您的DDL存在缺陷。在外键定义中有()，其中MySQL的解析器需要列名。

在完全删除工具之前，您可以查看如何使用它来定义实体之间的关系。将设计转发到数据库服务器时，这些关系会转换为外键。在SQL中查找外键定义包含()的表。那些看起来可能是错误设计的关系。

专业提示。在错误1064上，标准的MySQL错误消息如下所示：

  

...在'blah blah blah ...

附近使用正确的语法

单引号中的文本以SQL不能理解的SQL的第一个字符开始。在你的情况下，它以)开头，这意味着你的SQL中的一些紧密括号导致MySQL服务器呕吐。

弱实体：我们 - 强实体：SE - 主键：PK - 外键：FK

我使用的是MySQL Workbench而且我没有编写代码。 mySQL Workbench做了我告诉它的事情，但是我指示了错误的事情，因为我试图以错误的方式创建WE：

1. 我一次一个地运行查询（正如Sablefoste指出的那样），并注意到只有WE有问题
2. 我检查了所有WE。在FK标签上，我使用了它所依赖的强实体的FK和PK的相同名称。（正如Michael Berkowski指出的那样）
3. 当我构建WE时，我将强实体的PK定义为WE的PK，然后我进入FK选项卡并在WE列和参考列之间进行标准匹配。我不应该把它定义为WE的PK首先。

问题解决了。 感谢大家的帮助
