title: How to run batch file from within PL/SQL procedure
body: <p>I have a batch file which will execute some .exe which do some operations (like connecting to DB, fetching data, insert data etc...)<br>
  All the things are configured in the batch file and when I run it, it works good.</p>
  
  <p>But, I want to invoke this <strong>batch file</strong> from a <strong>PL/SQL procedure</strong>.<br>
  this procedure should invoke this batch file first, and after the execution of the batch file, it will have it's own SQL operations.</p>
  
  <p>How can I proceed to do this?</p>
