Cakephp Mysql查询

Question

如何在cakephp格式中编写以下查询？

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); 

通过使用这个你不要担心嵌套阵列
