title: Replace dot with comma on SELECT
body: <p>I would like to replace any 'dot' character in my query string, on <code>SELECT</code>ing fields from database.</p>
  
  <p>I'll need to modify lots of queries, I'm willing there's a function that will work to all columns on <code>SELECT</code>. I mean something like this <code>SELECT DOT_TO_COMMA(*) FROM...</code></p>
  
  <p>Right now what I have:</p>
  
  <p><code>SELECT price, lastprice FROM products</code></p>
  
  <p><code>OUTPUT: 22.10, 5.24</code></p>
  
  <p><code>EXPECTATION: 22,10, 5,25</code></p>
