Php PDO绑定两个值数组

我在

INSERT

statemnt

foreach

    public function getClients()
{

    helper::putToLog("\n----- getClients\n", true);

    $managedCustomerService = $this->user->GetService('ManagedCustomerService', ADWORDS_VERSION);

    $selector = new Selector();
    $selector->fields = array("CustomerId", "Name", "CurrencyCode");

    $graph = $managedCustomerService->get($selector);

    if (isset($graph->entries)) {
        $accounts = [];

        foreach ($graph->entries as $account) {
            $accounts[$account->customerId] = $account;            
        }

        helper::putToLog('Clients found: '.count($accounts)."\n", true);

    } else {
        helper::putToLog('Clients not found'."\n", true);
        return false;
    }


    $sth = $this->db->prepare('UPDATE `adwords_clients_google` set status = 2');
    $sth->execute();
    $sth = null;



    $queryClients = "INSERT INTO `adwords_clients_google` (`client_foreign_id`, `status`, `client_name`, `client_currency`) VALUES";

    foreach($accounts as $account) {

        $queryArr[$account->customerId] = "(".$account->customerId.",  1, :".$account->customerId.", :".$account->customerId."_currencyCode)"; 

        $nameArr[$account->customerId] = $account->name;
        $currencyArr[$account->customerId."_currencyCode"] = $account->currencyCode;


    }

    $queryClients .= implode(',', $queryArr) . " ON DUPLICATE KEY UPDATE `status` = VALUES(`status`), `client_name` = VALUES(`client_name`) ";

    $sth = $this->db->prepare($queryClients);

    foreach ($nameArr as $key => $value) {
        $sth->bindValue(":$key", str_replace("'", "\'", $value), PDO::PARAM_STR);
    }

    foreach ($currencyArr as $key => $value) {
        $sth->bindValue(":$key", $value, PDO::PARAM_STR);
    }

    print_r($sth);

    try {
        if ($sth->execute()) {
            helper::putToLog('ok queryCampaignArr, inserted rows: ' . $sth->rowCount());
        } else {
            helper::putToLog('not ok', true);
        }
    } catch (Exception $ex) {
        helper::putToLog($sth->debugDumpParams(), true);
        helper::putToLog("ERROR: ".$ex->getMessage(), true);
    }

    return true;
}

我需要绑定两个值数组

$nameArr

和

$currencyArr

。我没有收到任何错误，但列

client\u currency

为空，即使数组

$currencyArr

包含所有必需的值。怎么了？

看起来您还没有掌握预处理+参数化语句的概念。
您只需准备一次，然后使用不同的参数（一次或多次）执行它们

$sth = $this->db->prepare('
    INSERT INTO
        `adwords_clients_google`
        (`client_foreign_id`, `status`, `client_name`, `client_currency`)
    VALUES
        (:id, 1, :name, :currency)
    ON DUPLICATE KEY UPDATE
        `status` = VALUES(`status`),
        `client_name` = VALUES(`client_name`)
');
$sth->bindParam(':id', $id);
$sth->bindParam(':name', $name);
$sth->bindParam(':currency', $currency);
foreach($accounts as $account) {
    $id = $account->customerId;
    $name = $account->name;
    $currency = $account->currencyCode;
    $sth->execute();
}

如果您没有任何错误消息/日志条目，请确保PDO实例的设置为PDO:：ERRMODE_EXCEPTION

编辑：为了说明这一点，这里有一个：

---

当您使用当前值时，当前列的数据类型是什么；我想创建一个查询并只执行一次，就像在我上面的代码中一样，您创建了很多查询并多次执行它们。您为什么要这样做？特别是在使用prepare（）时？因为我需要在重复键更新的长查询

结束时添加
状态`=值（
状态
），
客户端名称
=值（
客户端名称
）”，`不是多次执行语句的有效原因。不这样做违背了准备好的语句的目的（部分）。非常感谢您的解释。我不知道有什么问题，但表中的字段
client\u currency
保持为空。
$account->currencyCode
有值，所有其他字段都可以正常工作，但不是这个字段。
