title: MySQL update query does not work #1064
body: <p>Can anyone tell me what is wrong with this Query ?</p>
  
  <pre><code>UPDATE
      violetta.navi__stop
  SET
      violetta.navi__stop.endHour = VB.endHour
  FROM
      violetta.navi__stop AS V
  INNER JOIN
      violetta_back.navi__stop AS VB
  ON V.code = VB.code
  </code></pre>
  
  <p>This code sample works for me on my database:</p>
  
  <pre><code>SELECT
  V.code, V.endHour
  FROM
      violetta.navi__stop AS V
  UNIQUE
      violetta_back.navi__stop AS VB
  ON V.code = VB.code
  </code></pre>
