Question

最近我一直在从普通的php迁移到ASP.NET。由于我不再使用PHP，我认为最好将MSSQL与sql express一起使用，而不是使用phpmyadmin坚持使用MySql。

我有一个MySql数据库，我想转移到sql express。有没有方便的方法呢？

我已经尝试将数据库导出到sql文件，但是在SSMS中打开脚本时会出现很多错误。我试图解决它们，但我甚至不了解它们中的大多数。

这是我正在使用的sql文件：（这里没有敏感数据，所有密码都是占位符。）

MySQL的SQL方言与SQL Server没有直接兼容，特别是在DDL方面。

您可以尝试SQL Server Migration Assistant，但需要在迁移后验证您的数据。有更详细的信息here。

但是，我见过的大多数迁移完全是手动的。创建新表，将旧表转储为CSV，然后将CSV导入新数据库。

然后，无论您采用哪种方式，都要验证并测试，验证和测试，验证和测试，并保留旧数据库几年，以便在您错过的内容中咬你。老实说，除非你真的需要SQL Server中的功能，否则我可能不会转向它，因为如果你的数据库太大，你可能需要许可它。

将SQL数据库从MySql（phpmyadmin）迁移到MSSQL（sql express）
