title: Event occuring for each row separatly
body: <p>I want to create an Event for Table :-</p>
  
  <pre><code>ACCOUNTS(id char(5),balance decimal(10,2), date_created date)
  </code></pre>
  
  <p>Value for the <code>DATE_CREATED</code> column will always be = <code>NOW()</code>, i.e. the date when the row was inserted in the table</p>
  
  <p>I want that the balance for each row gets increased by 2% after <strong>every 31 Days</strong>, according to its  <code>DATE_CREATED</code> column, i.e. after (<code>DATE_CREATED+31 Days</code>) for each row.</p>
  
  <p>I wanted to know whether it is possible or not and if it is possible then what would be the code for it?</p>
