PHP mysql查詢來填充條形圖最近7天

我有一個條形圖來填補這個星期一到星期天每週的每一天的7個總和1。PHP mysql查詢來填充條形圖最近7天

週一是工作周的開始，週日是本週的最後一天。

數據庫中的數據如下所示。

user1|2013-04-13 16:53:55|1 
user1|2013-03-13 16:53:55|1 
user1|2013-03-13 15:53:55|1 
user1|2013-02-13 09:53:55|1 
user1|2013-04-13 07:53:55|1 
user2|2013-03-13 15:53:55|1

行數是爲每個用戶

總和下面是找出一週中的天的方法。

     $dates['sunday']['evening'] = date('Y-m-d 23:59:59', strtotime('Sunday last week'));  
    }

我應該爲每週的每一天創建7個查詢1嗎？

SELECT myDateTime FROM `mylog` WHERE myDateTime >= $dates['monday']['morning'] AND myDateTime <= $dates['monday']['evening']

還是有更簡單更有效的方法嗎？

謝謝。編輯1 ==================== ========

這是我到目前爲止。

SELECT date(myDateTime) , sum(myValue) 
FROM mylog 
GROUP BY date(myDateTime)

如何指定我想要的星期一的日期？

有沒有辦法讓它變成1查詢而不是7？

謝謝。

哇，這很痛苦看 – 2013-04-15 02:47:15

是的..我知道，但它的工作原理，但我想知道一個更好的方式，所以而不是隻是要求，並沒有提供任何代碼，至少我做了第一次。 –

很好的讚揚，但我不知道什麼樣的期望輸出是基於該代碼，你不能在查詢中一天一組嗎？ – 2013-04-15 03:05:39

我想你想要的可能是這個。雖然我可能是錯的

SELECT user, DAYOFWEEK(myDateTime) as day_of_week, SUM(myValue) as total 
FROM mylog 
WHERE myDateTime >= DATE_FORMAT(NOW() - INTERVAL 1 WEEK, "%Y-%m-%d") 
GROUP BY user, DAYOFWEEK(myDateTime)

希望這是相當不言自明的？ WHERE子句爲您提供上週的所有記錄，而GROUP BY將首先按用戶分組，然後是星期幾（1 =星期日）。手冊是http://dev.mysql.com/doc/refman/5.1/en/date-and-time-functions.html#function_dayofweek這個東西。所以你應該最終得到類似

user | day_of_week | total 
------+---------------+------- 
user1 | 1    | 23 
user1 | 2    | 14 
... 
user1 | 7    | 65 
user2 | 1    | 12 
user2 | 2    | 78

等等。這似乎是你一開始就問的問題？
