title: Change SQLite database mode to read-write
body: <p>How can I change an SQLite database from read-only to read-write?</p>
  
  <p>When I executed the update statement, I always got:</p>
  
  <blockquote>
    <p>SQL error: attempt to write a readonly database</p>
  </blockquote>
  
  <p>The SQLite file is a writeable file on the filesystem.</p>
