Question

如何以 cakephp 格式编写以下查询？

SELECT COUNT( ip_address ) AS num_values
FROM property_viewers
GROUP BY property_viewers.ip_address
ORDER BY property_viewers.id DESC

Answer 1

 $this->model->find("count",array("fields"=>"ip_address",'group'=>'property_viewers.ip_address','order'=>'property_viewers.id DESC'))

Answer 2

 $options['fields'] = array("ip_address");
 $options['group']  = array("property_viewers.ip_address"); 
 $options['order']  = array('property_viewers.id DESC');
 $this->model->find("count",$options);

通过使用它，您不必担心嵌套数组
