更新準備好的語句不起作用

Question

此SQL不起作用，我試圖用rowCount（）和print_r（$ array）修復它幾個小時，但沒有運氣。

感謝所有幫助！

$sql=" UPDATE Listing SET 
     rentStartDate = :rentStartDate, 
     rentEndDate = :rentEndDate, 
     backyard = :backyard, 
     pricePerMonth = :pricePerMonth, 
     noOfBathrooms = :noOfBathrooms, 
     roomCapacity = :roomCapacity, 
     currentNoOfuser = :currentNoOfuser, 
     accessToPublicTrans = :accessToPublicTrans, 
     parkingSpace = :parkingSpace, 
     minimumLengthOfStay = :minimumLengthOfStay 
     WHERE address = :address "; 

    $stmt = $db->prepare($sql); 

    $stmt->bindValue(':address', $address); 
    $stmt->bindValue(':rentStartDate', $rentStartDate); 
    $stmt->bindValue(':rentEndDate', $rentEndDate); 
    $stmt->bindValue(':backyard', $backyard); 
    $stmt->bindValue(':pricePerMonth', $pricePerMonth); 
    $stmt->bindValue(':noOfBathrooms', $noOfBathrooms); 
    $stmt->bindValue(':roomCapacity', $roomCapacity); 
    $stmt->bindValue(':currentNoOfuser', $currentNoOfuser); 
    $stmt->bindValue(':accessToPublicTrans', $accessToPublicTrans); 
    $stmt->bindValue(':parkingSpace', $parkingSpace); 
    $stmt->bindValue(':minimumLengthOfStay', $minimumLengthOfStay);  

    $stmt->execute();

試試這個樣：

$sql=" UPDATE Listing SET 
     rentStartDate = ?, 
     rentEndDate = ? 
     WHERE address = ?"; 

    $stmt = $db->prepare($sql); 

    $stmt->bind_param('sss', $rentStartDate,$rentEndDate,$address); 

    $stmt->execute();
