代碼點火器中AND的有效記錄

Question

我該如何在codeigniter中的活動記錄中寫入此查詢。

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

我試過這個代碼，但給了一個空的數組。

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

Answer 1

只要沒有數組，你可以嘗試一下：我的查詢與下面的查詢工作這裏的條件相隔;創建和操作。

 $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

簡單地重複了兩遍像這樣：

$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

從笨教程：

$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();
