title: Read a Text/CSV file from an SQL statement
body: <p>I wish to use an external Text/CSV file to read data and run an SQL Query. Is this possible without using the External_Table concept? I do not have write permissions in the DB, hence cannot create a temp table in the DB.</p>
  
  <p>Basically, I have a list of employee numbers (around 100) in a text file, using which I wish to run the following query each time:</p>
  
  <pre><code>SELECT emp_record FROM emp_data WHERE emp_no = "@file-containing-number"
  </code></pre>
  
  <p>I have to run a series of tasks on these and they are in no particular order or sequence, but have been provided in that text file as a list. </p>
  
  <p>I am using the TOAD client and have only read-only permissions on the DB I connect to.</p>
