从特定模式中查找并汇总mysql字段

I have in a mysql table the number of downloads for a specific file.

I use the following code to fetch the number of downloads:

<?php $debname = 'com.dev.package_1.0-1_iphoneos-arm.deb'; ?>  

<?PHP include("../../config.php");
$query = "SELECT stats FROM download WHERE filename =  '".$debname."'";
$result = mysql_query($query);
while ($row = mysql_fetch_array($result)) {
echo $row[0];
}
?>

Sometimes, i update the packages and the name of the new package will be changed, for example: com.dev.package_2.1-1_iphoneos-arm.deb

This will then make the page display the counts of the new package which are reset to 0

Therefore, I'm trying to find a way to get the total number of downloads for all the versions

For example:

filename                                |     stats
________________________________________|_________________
com.dev.package_1.0-1_iphoneos-arm.deb  |       25
com.dev.package_2.1-1_iphoneos-arm.deb  |       2
________________________________________|_________________
Total Downloads of com.dev.package      |       27

So I want to display on my page the sum of the 2 file which is 27

EDIT:

$query = "SELECT sum(stats) AS sum FROM download WHERE filename LIKE '%com.dev.package%'";


echo $row[sum];

If you're looking to get the individual stats for each of the products (edited to meet upwith OP's comments) -

SELECT sum(`stats`) AS `Stats` 
FROM `download` 
WHERE `filename` 
LIKE '%com.dev.package%'
