根據通過日期范圍在mysqlcake php中每周分組數據

我希望根據我從前端經過的“開始”和“結束”日期，每周從中獲取數據。 因此，讓我們假設想要從'2014-07-15'到'2014-09-15'的數據應該每周匯總，並給出每個項目在特定一周內狀態為（2,3,4）的所有工作的總和。

我的結果應該是這樣的

+--------------+---------------+---------------------+
| project_name | reviewed_jobs | modified            |
+--------------+---------------+---------------------+
| Project 1    |             0 | 2014-07-15 14:38:35 |
| Project 1    |             0 | 2014-07-22 14:38:35 |
| Project 1    |             1 | 2014-07-29 14:38:35 |
| Project 1    |             3 | 2014-08-05 14:38:35 |
| Project 1    |             2 | 2014-08-12 14:38:35 |
| Project 1    |             2 | 2014-08-19 18:23:12 |
| Project 1    |             1 | 2014-08-26 19:48:48 |
| Project 1    |             2 | 2014-09-02 18:18:39 |
| Project 1    |             0 | 2014-09-09 14:38:59 |
| Project 2    |             0 | 2014-07-15 14:38:35 |
| Project 2    |             0 | 2014-07-22 14:38:35 |
| Project 2    |             0 | 2014-07-29 14:38:35 |
| Project 2    |             0 | 2014-08-05 14:38:35 |
| Project 2    |             1 | 2014-08-12 14:38:35 |
| Project 2    |             2 | 2014-08-19 18:23:12 |
| Project 2    |             0 | 2014-08-26 19:48:48 |
| Project 2    |             0 | 2014-09-02 18:18:39 |
| Project 2    |             0 | 2014-09-09 14:38:59 |
+--------------+---------------+---------------------+

到目前為止，我嘗試使用原始查詢和Cake php方法進行的操作：

原始查詢：

SELECT projects.name as project_name, 
SUM(if((jobs.status=2 || jobs.status=3 || jobs.status=4), 1, 0)) as reviewed_jobs, 
jobs.modified FROM jobs LEFT JOIN projects ON jobs.project_id=projects.id 
WHERE jobs.modified >= '2014:08:03 00:00:00' AND jobs.modified <= '2014:09:03 23:59:59' 
GROUP BY projects.name, WEEK(jobs.modified) 
ORDER BY DATE(jobs.modified) ASC;

但它給出以下結果

+--------------+---------------+---------------------+
| project_name | reviewed_jobs | modified            |
+--------------+---------------+---------------------+
| Project 1    |             3 | 2014-08-03 14:38:35 |
| Project 1    |             2 | 2014-08-10 14:38:35 |
| Project 2    |             1 | 2014-08-14 14:38:35 |
| Project 2    |             2 | 2014-08-23 18:23:12 |
| Project 1    |             3 | 2014-08-23 19:48:48 |
| Project 1    |             1 | 2014-08-29 18:18:39 |
| Project 1    |             2 | 2014-09-03 14:38:59 |
+--------------+---------------+---------------------+

這顯然是不希望的，並且與我想要的有所不同，並且存在一些潛在的問題，例如

1. 如果沒有得到特定日期的數據（在這種情況下，即2014-08-17），它將跳過該周或從下一個可用日期開始計數。

2. 結果不是根據查詢中傳遞的日期，而是根據表中的數據（表中可用的日期）。

CakePHP方式：

$options['joins']=array(array('table' => 'projects',
    'alias' => 'Project',
    'type' => 'LEFT',
    'conditions' => array(
        'Project.id = Job.project_id',
    )
));

$options['fields'] = array(
    'Project.name',
    'SUM(if((Job.status=2 || Job.status=3 || Job.status=4), 1, 0)) as reviewed',
    'DATE(Job.modified) as modified'
);

$options['order'] = array('modified'=>'ASC');

$options['conditions']=array(
    array("Job.modified >=" => $from_date->format("Y-m-d") . ' 00:00:00'),
    array("Job.modified <=" => $to_date->format("Y-m-d") . ' 23:59:59')
);

$options['group'] = array('Project.name', 'WEEK(Job.modified)');

任何幫助都將是可觀的

謝謝

在mysql中，您將需要另一個包含所有星期幾的表，以便您也可以加入該表，並因此返回Jobs表中沒有任何條目的星期幾。

快速而骯臟的構建周數據的方法：

SELECT STR_TO_DATE(CONCAT(yr.yy,'-',wk1.d,wk2.d,'-01'), '%Y-%u-%w') yyyywkd FROM
(SELECT 0 d UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5) wk1,
(SELECT 0 d UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9) wk2,
(SELECT '2013' yy UNION SELECT '2014') yr
WHERE CONCAT(wk1.d,wk2.d) > 0 AND CONCAT(wk1.d,wk2.d) < 54

在子作業中加入作業表的子查詢中嘗試此操作。
