导读：我有一张桌子如下 – 现在我需要报告每小时,每周,每月和每年的总计数.它可能有0,但应该包含在结果中.例如,我需要如下结果 – $hourlyResult = array('00:01' = '5','00:02' = '9','00:03' = '50','00:04' = '5',............................'00:55' = '95',

$hourlyResult = array(
'00:01' => '5','00:02' => '9','00:03' => '50','00:04' => '5',..............

'00:55' => '95','00:56' => '0','00:57' => '20','00:58' => '33','00:59' => '5',);

$weeklyResult = array(
'SAT' => '500','SUN' => '300'
.............
.............
'FRI' => '700'
);

如何在cakephp 3中构建查询？我得到以下链接,但不能到目前为止.

GROUP BY WEEK with SQL

我做了什么 –

$this->loadModel('Searches');   
    $searches = $this->Searches
        ->find('all')
        ->select(['created','count'])
        ->where('DATE(Searches.created) = DATE_SUB(CURDATE(),INTERVAL 1 DAY)')
        ->group(WEEK(date))
        ->hydrate(false)
        ->toArray();
    pr($searches);

解决方法

这是你如何做到的.

按年计算

$query = $this->Searches->find();
    $query = $this->Searches
        ->find()
        ->select([
            'total_count' => $query->func()->sum('count'),'year' => $query->func()->year(['created' => 'literal'])
        ])
        ->group(['year'])
        ->hydrate(false);

要么

$query = $this->Searches
        ->find()
        ->select(['total_count' => 'SUM(count)','year' => 'YEAR(created)'])
        ->group(['year'])
        ->hydrate(false);

按周计算

$query = $this->Searches->find();
    $query = $this->Searches
        ->find()
        ->select([
            'total_count' => $query->func()->sum('count'),'day_of_week' => $query->func()->dayOfWeek('created')
        ])
        ->group(['day_of_week'])
        ->hydrate(false);

要么

$query = $this->Searches
        ->find()
        ->select(['total_count' => 'SUM(count)','day_of_week' => 'DAYOFWEEK(created)'])
        ->group(['day_of_week'])
        ->hydrate(false);

以同样的方式获得按小时或月计的总和.
在这里你可以阅读约CakePHP > Using SQL Functions和date and time functions in MySQL.
