title: MySQL SUM of a single column with a single row
body: <p>this question is about MySQL.</p>
  
  <p>I want to know if I can SUM a column from a single row, for example I have a column in which is written "5 21 10", instead of one column for every value (one for 5, one for 21, one for 10), I want to use somehow SUM at this column and it should return 36.</p>
  
  <p>It's possible ? If yes, how ?</p>
  
  <p>Thanks.</p>
