Question

Let’s say I have this table in my database:

Each time is a UNIX timestamp that range from December 6 to December 14(today). Some rows have the same day but not the same time (ie: Dec 14 8:39PM, Dec 14 10:21 PM) and such.

However, I’m trying to make a mysql query that will add up all gained points for each day.

I currently have a while list that goes down the list sorted by uid because UID is the id of the user.

This is my currently while query:

$get_statuses = mysql_query("SELECT * FROM `history` 
                             WHERE `uid` = '$logged[id]' 
                             ORDER BY `id` DESC LIMIT 50");

Assuming I use this $fullDate = date("F j, Y", $status['4']); for each current loop beacuse I did this while ($status = mysql_fetch_array($get_statuses)) {...}, how do I do this?

Maybe a SELECT(SUM)?

Answer 1

Use this query.

SELECT Date(From_unixtime(`time`)) AS `Date`, 
       Sum(`gained`) 
FROM   `tbl` 
WHERE `uid` = '$logged_id'
GROUP  BY `Date` 
ORDER BY `id` DESC 

You can add More where condition here. Like

From_unixtime(`time`) >= '2012-12-06' 
AND
From_unixtime(`time`) <= '2012-12-14'
