title: Understanding mysql
body: <p>I have a mysql select query with following condition:</p>
  
  <pre><code>Select...
  FROM ...
  ...
  AND c.deleted != '1'
  </code></pre>
  
  <p>In the table, there will always be more records with deleted = '0' than deleted = '1'</p>
  
  <p>so I want to know which is faster:</p>
  
  <pre><code>AND c.deleted != '1'
  </code></pre>
  
  <p>or</p>
  
  <pre><code>AND c.deleted = '0'
  </code></pre>
  
  <p>or are they same?</p>
