Question

我正在尝试使用SELECT *和SUM（）函数从数据库表中获取结果。 sql查询是：

SELECT *，SUM（msg_send）AS msg_send FROM msg_campaigns

现在如何在cakephp3中编写此查询。

我正在尝试这个：

$this->loadModel('MsgCampaigns');  
$SmsDetails = $this->MsgCampaigns->find('all',[ 
'conditions'=>['YEAR(date_time)'=>date('Y')],
'fields'=>['msg_send'=>'SUM(msg_send)','msg_failed'=>'SUM(msg_failed)']
]);

但我不知道如何使用SELECT *。请帮忙

Answer 1

检查how to use SQL functions和how to select all fields上的CakePHP查询生成器。

$query = $this->MsgCampaigns->find();
$query
    ->select([
        'sum_msg_send' => $query->func()->sum('msg_send'),
        'sum_msg_failed' => $query->func()->sum('msg_failed')
    ])
    // passing the table instance to the `select` function, selects all fields
    ->select($this->MsgCampaigns);

$query->execute();
