How to DROP a database with character '?' in its name?

Question

Just trying out ubuntu server on my pc and have been testing some commands including mysql. I'm not sure why phpMyAdmin permitted me to create a database like this 'testing?db'. I'm trying to drop this database via SSH but I get this error:

mysql> show databases
    -> ;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| phpmyadmin         |
| testing?db         |
| testing_db         |
| wp                 |
+--------------------+
6 rows in set (0.00 sec)

mysql> DROP DATABASE testing?db;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '?db' at line 1
mysql>

I tried creating a database with a '?' in it and it also gives me syntax error. via ssh. so how do I remove this database?

Answer 1

Try:

DROP DATABASE `testing?db`;
