title: Split GROUP_CONCAT result into separate columns
body: <p>This query:</p>
  
  <pre><code>SELECT
  GROUP_CONCAT(
      DISTINCT (CONVERT(SaleYear, CHAR(8)))
      ORDER BY
          SaleYear ASC
  ) AS SaleYears
  FROM
      tblsales
  WHERE
      Municipality = 'Oakville';
  </code></pre>
  
  <p>Produces this result:</p>
  
  <pre><code>1980,1981,1983,1985,1986,1988,1989,1990,1991,1992,1993,1994,1995,1996,1997,1998,1999,2000,2001,2002,2003,2004,2005,2006,2007,2008,2009,2010,2011,2012,2013
  </code></pre>
  
  <p>All of the values are contained in the same column. What do I need to do if I want each value to be in a separate column?</p>
