select count of records group by month in cakephp 3

Question

I'm using CakePHP 3.x+

I have to show a graph on the page and thus want to build script for that.

I have to select count of records group by month for current year.

This is what I have tried.

$graph = $this->GenerateVideos->find()
        ->select('COUNT(id)', 'MONTH(created)')
        ->where(['YEAR(created)' => date('Y')])
        ->group(['MONTH(created)']);

which generates sql like

'sql' => 'SELECT GenerateVideos.COUNT(id) AS GenerateVideos__COUNT(`id`) FROM generate_videos GenerateVideos WHERE YEAR(created) = :c0 GROUP BY MONTH(created) ',
'params' => [
    ':c0' => [
        'value' => '2018',
        'type' => null,
        'placeholder' => 'c0'
    ]
],

But this is giving error as

Error: SQLSTATE[42000]: Syntax error or access violation: 
1064 You have an error in your SQL syntax; check the manual that 
corresponds to your MySQL server version for the right syntax to use near '(`id`) 
FROM generate_videos GenerateVideos WHERE YEAR(created) = '2018' GROUP BY' at line 1 

Answer 1

Try using an array in your ->select() value:

->select(['COUNT(id)', 'MONTH(created)'])

In the book, it always shows an array, and it doesn't appear to be utilizing your second select value.

Or, per the book here, you could try this:

$query = $this->GenerateVideos->find();
$query->select(['count' => $query->func()->count('id'), 'month' => 'MONTH(created)']);
$query->where(['YEAR(created)' => date('Y')])
$query->group(['month' => 'MONTH(created)']);
