title: Selecting max value from calculated column in mysql
body: <p>I have a mysql select statement which goes like this:</p>
  
  <p>Select a,b,calculated_column from table t1;</p>
  
  <p>I come up with the calculated_column based on some logic and calculated_column is NOT a column in table t1.</p>
  
  <p>How do I make this select statement return only the max value of the calculated_column?</p>
