title: Alternative to except in MySQL
body: <p>I must write a Query like this in MySQL:</p>
  
  <pre><code>SELECT * 
  FROM Tab1
  EXCEPT
  SELECT * 
  FROM Tab1 
  WHERE int_attribute_of_Tab1&gt;0
  </code></pre>
  
  <p>but MySQL doesn't support the keyword <strong>EXCEPT</strong>. 
  Is there a <em>standard mode</em> to use correctly another operator that simulate the except in MySQL? </p>
