I recently used the MySQL database. I started the latest MySQL installation package. After I installed the package directly and configured it according to some instructions on the internet, I always reported error 1067 when I started the service. Finally, I got down to the XAMPP, which is a big artifact. I don't have to configure MySQL myself, but also come with PHP and Apache. I directly operate databases in the browser, but I still like to use navicat for MySQL.
There are many examples of using MySQL on the Internet, such as Google, Baidu, and unity3d. However, if you copy the code and report various errors, the main reason is that the dll version is incorrect.
Finally, I went to the unity3d forum to go to a connection [http://forum.unity3d.com/threads/63364-unity-with-mysql#. it was very helpful to go through demo. Another method is described in this document. For details, see [http://wiki.unity3d.com/index.php/easy_mysql_submission#. This method does not need to directly use MySQL DLL. By accessing the server, it is very convenient for the server to handle it.
