title: MySql SELECT index benefits
body: <p>Are there significant benefits between the two SQL select ?</p>
  
  <pre><code>SELECT * FROM table USE INDEX (cod_clie) WHERE cod_clie = "example" AND pwd_clie = "example" LIMIT 1;
  
  SELECT * FROM table WHERE cod_clie = "example" AND pwd_clie = "example" LIMIT 1;
  </code></pre>
  
  <p>cod_clie is an INDEX field, of course!</p>
