获取从定义的月份到当月的每个月的数据

Question

I need to provide monthly reports of bandwidth used from our mysql database since a particular month and year eg November, 2009. I can output the correct data for any particular month using the following query;

$query='SELECT SUM(radacct.AcctInputOctets) AS uploads,SUM(radacct.AcctOutputOctets) AS downloads FROM radacct WHERE radacct.AcctStartTime BETWEEN "2010-11-00" AND "2010-12-00"';
    $result = mysql_query($query);
    $row = mysql_fetch_array($result);
    echo '<tr><td>December</td><td>'.$uploads.'</td><td>'.$downloads.'</td></tr>';

I need to put this into a loop which starts from a defined month ie $start='2009-11-00' and prints out a record for each month up to and including the current month. Regardless of what I try, I cant get it to work!

Answer 1

Add a grouping parameter:

SELECT year(radacct.AcctStartTime), month(radacct.AcctStartTime), ...
FROM ...
WHERE radacct.AcctStartTime > '2010-09-00'
GROUP BY year(radacct.AcctStartTime), month(radacct.AcctStartTime)

Which would give you summary data for every year/month that has at least one entry in the database, since Sep. 2010.
