2. Bugs

In the Javaweb class for the next semester of the sophomore year, my final assignment is a Red Cross online management system. When the system administrator for this system is removed and deleted, it is found that the administrator cannot be dropped.

The cause of the bug: I use the database is MySQL, the database does not have a password, connect to the database using anonymous users , but after using phpmyadmin connected to MySQL no longer allow anonymous users to connect, resulting in the situation can not be deleted.

I found this bug when I was doing a simple functional test of my own software, but it took a long time to find the cause of the bug. It is not known why phpMyAdmin causes this, and may be a protection mechanism, but the problem of connecting to a database without using phpMyAdmin is solved.
