mysql select sum group by date

Quick question, I have the following table

+-------------+---------------------+
| total       | o_date              |
+-------------+---------------------+
|          35 | 01-11-2009 19:32:44 | 
|        41.5 | 01-12-2009 22:33:49 | 
|        61.5 | 01-23-2009 22:08:24 | 
|          66 | 02-01-2009 22:33:57 | 
|       22.22 | 02-01-2009 22:37:34 | 
|       29.84 | 04-20-2009 15:23:49 | 
+-------------+---------------------+

I would like to add up the total for each month and group the total by month. So for instance Jan-> 138 Feb-> 88.2 Apr-> 29.84

Any clues about it. Thanks

This solution will give you the month name as a column of your resultset, followed by the total as required.

SELECT MONTHNAME(o_date), SUM(total) 
FROM theTable
GROUP BY YEAR(o_date), MONTH(o_date)

select year(o_date), month(o_date), sum(total)
from table
group by year(o_date), month(o_date);

Get Month And Year wise data from MySQL database:

SELECT MONTHNAME(o_date), YEAR(o_date), SUM(total) 
FROM the_table 
GROUP BY YEAR(date), MONTH(date)

SELECT SUM(total)
FROM table
GROUP BY MONTH(o_date)
