在salesforce中创建记录

Question

我正在尝试在Salesforce Enterprise中创建记录，但收到错误消息。

代码：

<?php

define("SOAP_CLIENT_BASEDIR", "soapclient");
require_once (SOAP_CLIENT_BASEDIR.'/SforceEnterpriseClient.php');
require_once ('userAuth.php');

try {
  $mySforceConnection = new SforceEnterpriseClient();
  $mySoapClient = $mySforceConnection->createConnection(SOAP_CLIENT_BASEDIR.'/enterprise.wsdl.xml');
  $mylogin = $mySforceConnection->login($USERNAME, $PASSWORD);

  $sObject1 = new stdclass();
  $sObject1->number__c = '20';
  $sObject1->name__c = 'testupdateCity';
  $sObject1->country__c = 'US';

  $response = $mySforceConnection->update(array ($sObject1), 'nisaion_01__c');

  print_r($response);

} catch (Exception $e) {
  print_r($mySforceConnection->getLastRequest());
  echo $e->faultstring;
}
?>

错误：

  

数组（[0] =＆gt; stdClass对象（[errors] =＆gt;数组（[0] =＆gt; stdClass对象（[消息] =＆gt;未在更新调用中指定的ID [statusCode] =＆gt; MISSING_ARGUMENT））[id] =＆gt; [成功] =＆gt;））

我做错了什么？
