title: Get only business days in oracle sql
body: <p>I wish to get only business days between the two dates. I know we have many solutions on my question but I am looking for something particularly for my example</p>
  
  <p>my sql query has a condition</p>
  
  <pre><code>WHERE DATE_FIELD BETWEEN '1-JAN-13' AND '31-MAR-13'
  AND (DATE_FIELD1 - DATE_FIELD2) &gt; 10
  </code></pre>
  
  <p>I wish to get only business days between the two dates and also I want that during the calculation of DATE_FIELD1 - DATE_FIELD2, it only considers business days and excludes weekends.</p>
