title: Basic SQL CURRENT_TIME() query
body: <p>I have a table with a column having date &amp; time. I have to get all the rows which have the date and time before the current time. So i have written the following </p>
  
  <pre><code>SELECT * FROM G_CARD_SCHEDULE WHERE TIME_TO_BE_SENT &lt; CURRENT_TIME()
  </code></pre>
  
  <p>And the table has the following column</p>
  
  <blockquote>
    <p>TIME_TO_BE_SENT = 2010-10-08 00:57:50</p>
  </blockquote>
  
  <p>But still 0 rows are returned by the SQL, what is wrong?</p>
