Question

I have a mysql table that looks like this:

id - year - value
-----------------
1  - 2004 - 10 
2  - 2005 - 15 
3  - 2006 - 8 
4  - 2006 - 14
5  - 2007 - 20
6  - 2008 - 25

I need to be able to fetch this array from mysql and have the the two 2006 values added together. How do I do this?

Answer 1

$query = "SELECT t.year, 
                 SUM(t.value) AS sumValue
            FROM table t
        GROUP BY t.year";

$result = mysql_query($query) or die(mysql_error());

// Print out result
while($row = mysql_fetch_array($result))
{
    echo $row['year']. " = ". $row['sumValue'];
    echo "<br />";
}
