title: Oracle TO_DATE not working
body: <p>I have this query which is not returning any rows. But there are records which are greater than 25-JUN-90 date. Why is it not working?</p>
  
  <pre><code>{SELECT employee_id, last_name,hire_date
     FROM employees WHERE hire_date &gt; TO_DATE('25-JUN-90','dd-mon-yy');}
  </code></pre>
