title: Sorting mysql varchar column with where condition
body: <p>I have a table with column points[VARCHAR]</p>
  
  <p>When I take the records with points greater than 80 and order by points in descending order. I get only numbers from 99. Actually I have points greater than 100. </p>
  
  <p>Tried the option of adding +0 but strange results in ascending order,
  gets data from points with 8</p>
