title: Cant drop database nor create database
body: <p>When I run mysql as root and run <code>SHOW DATABASES;</code> it shows that I have a <code>one_db</code> database, but when I run <code>DROP DATABASE one_db;</code> it outputs the following error:</p>
  
  <pre><code>ERROR 1008 (HY000): Can't drop database 'one_db'; database doesn't exist
  </code></pre>
  
  <p>I then try to <code>CREATE DATABASE one_db;</code> and outputs this error:</p>
  
  <pre><code>ERROR 1007 (HY000): Can't create database 'one_db'; database exists
  </code></pre>
  
  <p>How can I delete this database now?</p>
