title: Lua script to stop firing a query in mysql via mysql proxy
body: <p>I am a beginner to lua language.The main concept is when a user fire the <code>DROP TABLE</code> command in mysql it should not be executed.But he can fire all other commands as usual in mysql.But i don't want to use <code>GRANTS</code> for this.Is there any <code>luaScript</code> to perform this action via <code>mysql-proxy</code>?</p>
  
  <p>For example: </p>
  
  <pre><code>mysql&gt; DROP TABLE T1;
  Please wait for authentication
  </code></pre>
  
  <p>Also is <code>LuaSql</code> helpful to perform this task via <code>mysql-proxy</code>?</p>
  
  <p>Hope i made the idea clear.Someone help me solve out this issue.Thanks in advance.</p>
