title: How to return LOW VALUES HEX '00' in sql statement?
body: <p>I need to write into file (in the middle of the string) a LOW VALUES HEX'00'. </p>
  
  <p>I could do it using package utl_file using the next code <code>utl_file.put_raw(v_file, hextoraw('000000'))</code>. But I may do it only in the beginning and end of file, not in the middle of string. </p>
  
  <p>So, my question is: how to write a LOW VALUES HEX'00' in the select statement.
  I tried some variants like </p>
  
  <pre><code>Select ‘blablabla’ Q, hextoraw('000000'), ‘blablabla’ w from dual;
  </code></pre>
  
  <p>save it into <code>.dat</code> file, then open it in hex-editor but the result was different when using utl_file.</p>
  
  <p>Could anybody  (if it's possible) write a correct sql statement.   </p>
