PHP SQLSRV無效參數傳遞更新查詢

Question

我正在此錯誤

陣列（[0] =>數組（[0] => IMSSP [SQLSTATE] => IMSSP [1] => -14 [代碼] => -14 [2] =>一個無效參數傳遞給sqlsrv_query [消息] =>一個無效參數傳遞給sqlsrv_query））

代碼是：。

$sql_query = "UPDATE Subscription SET Status = ? where SubscriptionID = ?"; 
     $params = array(1, $subscription_id); 

     $stmt = sqlsrv_query($conn, $sql_query, $params); 

     if($stmt === false) { echo " Error occurred while updating in database. "; 
      die(print_r(sqlsrv_errors(), true));} 
     else {echo " Database updated successfully.";} 

有人幫我...謝謝

調試這個更多，你可以在查詢中硬編碼價值代替?，看看它的工作原理還是失敗？ $params是sqlsrv_query的可選參數

問題是$conn爲空。
