title: Python sqlite3 parameterized drop table
body: <p>I have a problem with dropping sqlite3 table in python. I am using standard <code>sqlite3</code> module. </p>
  
  <pre><code>self.conn = sqlite3.connect(...)
  
  sql = """ drop table ? """
  self.conn.execute( sql, (u'table_name',) )
  </code></pre>
  
  <p>gives me <code>OperationalError: near "?": syntax error</code>  </p>
  
  <p>When I change <code>sql</code> to:</p>
  
  <pre><code>sql = """ drop table table_name """
  </code></pre>
  
  <p>it works fine.</p>
