title: What does <> mean on SQL
body: <p>I was looking for what the &lt;> mean on sql syntax but it was hard to google for it since google removes my special characters. </p>
  
  <p>Specifically I was trying to figure out what the following means:</p>
  
  <pre><code>... AND (s1.skips &gt; 0 OR s1.fails &lt;&gt; 1 OR s2.skips &gt; 0);
  </code></pre>
  
  <p>Is there any clear documentation talking about the &lt;> clause?</p>
