代码点火器中AND的有效记录

Question

我该如何在codeigniter中的活动记录中写入此查询。

SELECT * FROM `post_ads` WHERE `dates` >= '2014-09-20' AND `dates` <= '2014-09-22' ORDER BY `dates` ASC 

我试过这个代码，但给了一个空的数组。

$where = "DATE(dates) BETWEEN '2014-09-20' AND '2014-09-22'"; 
    $query = $this->db->where($where)->get('post_ads'); 
    return $query->result(); 

Answer 1

只要没有数组，你可以尝试一下：我的查询与下面的查询工作这里的条件相隔;创建和操作。

 $this->db->where('dates >=', 2014-09-20); 
     $this->db->where('dates <=', 2014-09-22); 
     $this->db->order_by("dates", "asc"); 
     $query = $this->db->get('post_ads'); 
     return $query->result(); 

Answer 2

简单地重复了两遍像这样：

$this->db->select(); 
$this->db->from('post_ads'); 
$this->db->where('dates','2014-09-20'); 
$this->db->where('dates','2014-09-22'); 
$this->db->order_by('dates'); 

Answer 3

从笨教程：

$array = array('dates >=' => $to, 'dates <=' => $from); 
$this->db->where($array); 
$this->db->order_by("dates", "asc"); 
$query = $this->db->get('post_ads'); 
return $query->result();
