title: sql loader without using database password
body: <p>I have a CSV file which I need to upload into a database table. I have written an SQL loader for the same and am able to upload the csv in the table, but the  problem I am facing is that I am having to  hard code the password in the loader script itself.
  The entire thing is supposed to be automated, where user will be uploading file to a specific folder on the server. For this we will be using a shell script which will be fetching the file. Then using the SQL loader it will upload the values into the table.</p>
  
  <p>Is there any way to use the SQL loader without providing the password?</p>
