title: ALTER TABLE syntax - missing DIRECTORY keyword
body: <p>I am trying to alter a table in Oracle database by adding two new columns to it with SQL query as below:</p>
  
  <pre><code>ALTER TABLE Members 
        ADD annual_dues NUMBER(5,2) not null DEFAULT '52.50', 
        ADD payment_date DATE;
  </code></pre>
  
  <p>On executing it, I am getting an error as below:</p>
  
  <blockquote>
    <p>SQL Error: ORA-30649: missing DIRECTORY keyword</p>
  </blockquote>
  
  <p>I have played around it but it didn't help. What is wrong in the SQL query?</p>
