MySQL代码架构生成的代码什么都不做？

我正在使用MySQL来设计数据库，我正在使用工作台上的'SQL Create Script'选项导出用于生成数据库的代码。但是，当我运行代码并使用SHOW TABLES时，我得到空值，这可能意味着在数据库中没有创建表。这是已生成的代码（其长，但因为它是自动产生的错误可能是从设置导出时我了。）MySQL代码架构生成的代码什么都不做？

我使用SQL命令行客户端，并把代码，但它不起作用。

如果您通过phpmyadmin运行相同的脚本，会发生什么情况？也许这是一个权限/用户问题。 – markus

因为你使用命令行客户端作为你的数据库。这只会让你的电脑成为一个数据库，但并不完全具备专业数据库的所有功能。 MySQL工作台旨在为数据库导出更专业的代码。

既然你使用的是命令行客户端，我假设这是练习或某种功课？无论哪种方式，这都是代码在Command line客户端中的工作方式。尝试这个。
