title: &amp shown in url column in mysql. Display as stored in mysql
body: <p>I have a url that is displayed as this :
  <code>http://www.amazon.com/gp/product/0307408418/ref=s9_al_bw_ir01?pf_rd_m=ATVPDKIKX0DER&amp;amp;pf_rd_s=center-3&amp;amp;pf_rd_r=0ZHX172F5RRJXR7D5EKD&amp;amp;pf_rd_t=101&amp;amp;pf_rd_p=1313842642&amp;amp;pf_rd_i=283155</code></p>
  
  <p>What happens though is when I try to use the original url string in an sql query, I get an empty set. It is largely do due to the url encoded differently. I wanted to know then, how could I update the url string to properly query the database?</p>
