如何從MySQL中獲取數據並將它們在幾周內分組，並且按月分隔

Question

我擁有mysql數據庫並且擁有超過2年的數據。我怎樣才能使一個查詢的方式，它將得到的結果？：

January 
    Week 1 
     ... 
     data rows here 
     .... 
    Week 2 
     ... 
     ... 
    Week 3 
     ... 
     ... 
    Week 4 
     ... 
     ... 

February (same as above) 

這些領域的結構如下：

- date (in yyyy-mm-dd format) 
- job (integer autoincrement) 
- person (varchar) 

Answer 1

試試這個，它會產生輸出非常類似於一個由你需要

SELECT MONTH(date) AS MONTH, WEEK(date) AS WEEK, DATE_FORMAT(date, %Y-%m-%d) AS DATE, job AS JOB, person AS PERSON GROUP BY WEEK(date); 

Answer 2

GROUP BY year(record_date), MONTH(record_date) 

退房在MySQL中date and time functions。

Answer 3

它必須是查詢，或者你也可以使用ajax？使用AJAX你可以在JavaScript做一個循環：

date = [initial date] 
while date <= [final date] { 
    divUpdate = 'divrecs'; // will be used in updateDiv function 
    url = 'getrecs.php?date1='+date+'&date2='+(date+6); 
    conecta(url,updateDiv); 
    date = date+7; 
} 

而且裏面getrecs您的查詢將是：

$stmt = $dbh->prepare("select * from yourtable where date >= '".$_GET['date1']."' and date <= '".$_GET['date2']."'"); 
if ($stmt->execute()) { 
    while ($row = $stmt->fetch(PDO::FETCH_BOTH)) { 
     echo "Do anything with your data here: $row[1] etc<BR>"; 
    } 
} 

希望幫助！

Answer 4

SELECT MONTH(created_datetime) AS month, WEEK(created_datetime) AS week, DATE(created_datetime) AS date, COUNT(id) AS count FROM users WHERE date(created_datetime) BETWEEN '2017-05-01' AND '2017-12-31' GROUP BY month ORDER BY created_datetime

如果你想記錄日期明智的，你需要使用GROUP BY日期。
如果您想要每週記錄一次，則需要使用GROUP BY周。
如果您想每月記錄一次需要使用GROUP BY月份的記錄。
