如何在條件下使用max函數？CakePHP 3查詢生成器 - 如何在條件下使用max函數？
這就像在Translate SQL query to CakePHP 3.0下面的答案，但對我來說，我需要使用max函數和case子句（或條件的任何其他形式）：
$options['contain'] = array('Users');
$query = $this->Pictures->find('all', $options);
$query->select(['Users.username', 'Users.plan', 'Users.id']);
$query->select(['sum' => $query->func()->sum('size'),])
->select(['count' => $query->func()->count('*'),])
->select(['facebook' => $query->func()
->count('case when type = \'facebook\' then 1 else null end'),])
->select(['instagram' => $query->func()
->count('case when type = \'instagram\' then 1 else null end'),])
->select(['device' => $query->func()
->count('case when type = \'device\' then 1 else null end'),])
->group('user_id');
return $query;
感謝所有。
