title: Need a oracle function to conver string to bytes array
body: <p>I have a Column :</p>
  
  <pre><code>LOGIN_PWD  -&gt;  RAW(256 BYTE) 
  </code></pre>
  
  <p>I have to use a insert query to insert a hashed password string into this column. So is there any oracle function that can covert a string to bytes like </p>
  
  <pre><code>INSERT INTO TABLE_NAME (LOGIN_PWD) VALUES (convert.toBytes('hashed password'));
  </code></pre>
  
  <p>I did this using java program by using string.getBytes() methode on my local machine but for other env i cant use same program need to do it using query </p>
