title: MySQL event on given hour
body: <p>I want to create event that would run function daily on given time (to be more precise, 7:00 and 17:00), I've created this code:</p>
  
  <pre><code>DELIMITER |
  
  CREATE EVENT kill_sleepers_event
      ON SCHEDULE EVERY (7, 17) DAY_HOUR
      COMMENT 'Clean up sleepers at 7:00 and 17:00 daily!'
      DO
        BEGIN
          SELECT func();
        END |
  </code></pre>
  
  <p>Workbench doesn't show any syntax error, but when I try to run it, there is error:</p>
  
  <blockquote>
    <p>Error Code: 1241. Operand should contain 1 column(s)</p>
  </blockquote>
  
  <p>So I want to ask you if it's possible to have event with multiple launching time or I have to wrote them as two separate entities?</p>
