Adding all the results from all the fields.


Recommended Posts

Hello guys. Let's say I have my DB set up as: "SELECT * FROM playerinfo WHERE kills > 0"


Playerinfo has information about players, each player has kills. How to add up ALL the kills FROM ALL players?

What you are looking for is the SUM mysql function. For example


$res = mysql_query("SELECT SUM(kills) as num_kills FROM playerinfo WHERE kills > 0");
$row = mysql_fetch_array($res);
echo "There are : ". $row['num_kills']." total kills";


EDIT: bah sniped, but ill post anyways, as I have an example

Hello. Thanks for the feedback.


I try doing it this way:

$total_kills = mysql_query("SELECT SUM(kills) FROM playerinfo", $connect);
echo $total_kills;


That outputs: "Resource id #5"


mysql_query only gives you the id location in the database. You have to apply that to an array to actually pull data out of it. Use:




directly after

$total_kills = mysql_query("SELECT SUM(kills) FROM playerinfo", $connect);
