AND代碼點火器的活動記錄

Question

如何在codeigniter中的活動記錄中編寫此查詢。

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

我嘗試了這段代碼但是給了一個空數組。

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

Answer 1

簡單地重復兩次，如下所示：

$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 2

如果沒有數組，你可以嘗試在條件分開的地方; 創建AND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 3

從codeigniter教程：我的查詢使用以下查詢：

$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();
