How to sort data from Mysql table by month

Posted on 2004-03-26

Hello there,

I have created a PHP page that retrieves two columns from a MySQL db (date and amount). What i can't seem to comprehend is the next step... how to sum the amount and show it by month name and year as below.
The Mysql table i have consists of three columns:

-ID Autoincrement
-Date Date
-Minutes Int(11)

This is how i would like to have the data.

January 2001              45673
February 2001            34455
March 2001                23747
April 2001                  86464
May 2001                   6363
June 2001                   0
etc..

Here is my PHP code so far...
----------------------------------
<?php
// connect to the database
include("../include/irm.inc");

$query = "SELECT Date, Minutes FROM tbl_Minutes ORDER BY Date";

$sth = $adb->prepare($query);
if($sth)
{
        $res = $sth->execute();
        $numrows = $sth->rows();
        for($i = 0; $i < $numrows; $i++)
          {
                $result = $sth->fetchrow_hash();
                $Date = $result["Date"];
                $Minutes = $result["Minutes"];
                PRINT "$Date  ";
                PRINT "$Minutes <BR>";
         }
        $sth->finish();
} else
{
    PRINT "Could not prepare query: ".$sth->errstr."<br>\n";
}
?>
------------------------------------------
Any pointers, ideas or examples would be greatly appreciated. Thanks alot.
Richard.

try this query:
$query = "SELECT date_formt(Date, '%M %Y') as Date , Minutes FROM tbl_Minutes ORDER BY Date";

Just a little change of CosminB's answer to add up the minutes for you:

SELECT date_formt(Date, '%M %Y') as Date , sum(Minutes) as Minutes FROM tbl_Minutes GROUP BY Date

snoyes, this does not add minutes but rather outputs as a different field the sum of all the minutes values for a given date...

richard, can't you store timestamps in the db and convert them afterward ? it usually ends up to be the best solution to avoid problems (of course the type of the field will NOT be 'timestamp' but rather INT(10), atherwise the timestamps will automatically change upon update )

otherwise, cosmin's solution will work as long as mysql properly interprets the content of the field (beware you can't mispell January for example)

good luck
