title: Increasing the size of Varchar2() in oracle
body: <p>Is it possible to increment the size of a column (say varchar2(25)) by 50? To be precise, I am not looking for something like this:</p>
  
  <pre><code>ALTER TABLE &lt;Table_name&gt; modify &lt;Column_name&gt; varchar2(75);
  </code></pre>
  
  <p>Rather, I am inquisitive about something that will increase the size by 50 or some other integer constant without the explicit calculation on the programmer part. </p>
  
  <p>PS: Please comment if I am not clear.</p>
