MySQL的＆笨更新多行

我有一個包含客房
的可用性表看起來是這樣的（遺憾的片段）MySQL的＆笨更新多行

我想要做什麼表是：當我有新的預訂時，將字段'idbook'更改爲預訂ID，每行的可用性爲1，具體取決於該書的日期（請參見：今日字段）和idroom。
在模型中我有這樣的代碼（介意「調試」）

 
function updateAvailability($data) 
    { 

$this->db->select('idbook'); 
    $this->db->where('idguests',$data['guestid']); 
    $this->db->where('valid_from',$data['from_date']); 
    $this->db->where('valid_to',$data['to_date']); 
    $this->db->where('idroom',$data['idroom']); 
    $query = $this->db->get('bookitbooking'); 

    $result = $query->row(); 
    $idbook = $result->idbook; 

    $changes = array(
     'idbook' => $idbook, 
     'availability' => 1 
    ); 
    $where = array(
     'today' => "BETWEEN '{$data['from_date']}' AND '{$data['to_date']}'", 
     'idroom' => $data['idroom'] 
    ); 

    $update = $this->db->update('bookitavailability',$changes,$where); 
    if($update === TRUE){ 
     echo "done"; 
    } else { 
     echo "wrong"; 
    } 

}

是有原因的，上面的代碼不工作，我有一個「完成」迴歸呼應，但在我的數據庫沒有變化。

請檢查「BETWEEN '{$數據[' FROM_DATE ']}' 和 '{$數據[' TO_DATE ']}'」，你在雙引號使用多個單引號.... – 2015-04-06 10:24:14

有你嘗試打印查詢？ – Raja 2015-04-06 10:26:44

是的，我剛剛做了，它產生了一個錯誤：[代碼]更新'可用性'SET' idbook' ='539'，'availability' = 1 WHERE'today' ='BETWEEN 2015-04-10和2015-04 -18'和'idroom' ='28'[/ code]你看到where語句是worng，給**今天= ... ** – tsompanis 2015-04-06 11:58:16

好... ...因爲我看到有一個問題，與我想要的，希望where子句不能正常工作，我做了一些修改我的代碼。
首先，我爲日期做了foreach（）循環，然後我在每個循環中傳遞了我想要的的日期，其中聲明。這是我如何「解決」它。


function updateAvailability($data) 
    { 
     $this->db->select('idbook'); 
     $this->db->where('idguests',$data['guestid']); 
     $this->db->where('valid_from',$data['from_date']); 
     $this->db->where('valid_to',$data['to_date']); 
     $this->db->where('idroom',$data['idroom']); 
     $query = $this->db->get('bookitbooking'); 

     $result = $query->row(); 
     $idbook = $result->idbook; 

     $changes = array(
      'idbook' => $idbook, 
      'availability' => 1 
     ); 

     $arrival = new DateTime($data['from_date']); 
     $departure = new DateTime($data['to_date']); 
     $interval = DateInterval::createFromDateString('1 day'); 
     $period = new DatePeriod($arrival, $interval, $departure); 

     foreach($period as $day){ 
      $this->db->where('idroom',$data['idroom']); 
      $this->db->where('today',$day->format('Y-m-d')); 
      $this->db->update('bookitavailability',$changes); 
     } 
    }

嘗試仔細檢查此字符串：

"BETWEEN '{$data['from_date']}' AND '{$data['to_date']}'"

到

"BETWEEN ".$data['from_date']." AND ".$data['to_date']

問題可能是$數據[ 'FROM_DATE']是一個字符串，所以它可能不會被upadting正確的行。

嘗試

"BETWEEN DATE(".$data['from_date'].") AND DATE(".$data['to_date'] . ")"
