title: Pass nls date format to SQL Loader control file
body: <p>Is this possible to pass NLS date forma to the SQL Loader control file? With query or through Linux/unix scripting. Is there a way to pass the value to the control file table column w/out hardcoding it please? 
  Oracle version is 11.2.</p>
  
  <pre><code>SELECT value 
    FROM v$nls_parameters
  WHERE parameter IN ('NLS_DATE_FORMAT', 'NLS_TIME_FORMAT')
