title: Avoid double quotes around column while spooling to csv from oracle
body: <p>I need to export a select query output to text file using spool. The output by default adds double quotes around the column. How to Prevent it?
  The query returns only one column. </p>
  
  <p>Ideally i need to remove headers as well as the double quotes from the output. below is the script file i use in oracle Developer. but heading is also not removed.</p>
  
  <pre><code>set echo off
  SET HEADING OFF
  SET PAGESIZE 0
  SET COLSEP ''
  spool 'D:\public\cvs_txPCG.txt'
  select /*csv*/ 
  pcg from temptx;
  spool off;
  </code></pre>
  
  <p>output</p>
  
  <pre><code>"PCG"
