php - PDO绑定(bind)错误

Question

我尝试从数据库获取一些值

$client_ids = array('client_id' => $this->arParams['client_id']);
 print_r($client_ids);
 $client_ids_in = implode(',', array_fill(0, count($client_ids), '?'));
 $query = "SELECT odc.curr_id FROM office.dictionary_currency AS odc LEFT JOIN office.adwords_clients_google AS oacg ON odc.curr_code = oacg.client_currency WHERE oacg.client_id IN ($client_ids_in)";
        $google_currency = $this->DB->prepare($query);
        $google_currency->execute($client_ids);
        $google_currency->setFetchMode(PDO::FETCH_ASSOC);
        $google_currency = $google_currency->fetch();
        $google_currency = $google_currency['curr_id'];

$client_ids看起来像

Array
(
    [client_id] => 15087
)

$query

SELECT odc.curr_id FROM office.dictionary_currency AS odc LEFT JOIN office.adwords_clients_google AS oacg ON odc.curr_code = oacg.client_currency WHERE oacg.client_id IN (?)

我收到一个错误

PHP Warning:  PDOStatement::execute(): SQLSTATE[HY093]: Invalid parameter number: parameter was not defined in /var/www/instruments/reports/report.php on line 531

这意味着，行中有错误

$google_currency = $this->DB->prepare($query);

出了什么问题？如何解决？

Answer 1

更改您的代码

 $client_ids = array('client_id' => $this->arParams['client_id']);

变成类似的东西

 $client_ids = array($this->arParams['client_id']);

所以$client_ids就像

Array
(
   0 => 15087
)
