Question

我正在尝试使用PHP PDO运行此SQL查询：

$stmt = $pdo_conn->prepare("select * from billing_pdf_archive where invoice_number = :invoice_number and sequence = :sequence ");

$stmt->execute(array(
                     ':invoicenumber' => $_GET["inv"], 
                     ':sequence' => $_GET["seq"]
                    )
);

$result = $stmt->fetch();

注意：$_GET["inv"]和$_GET["seq"]在回显时显示数据

但我收到此错误

致命错误：未捕获异常'PDOException'，消息'SQLSTATE [HY093]：参数号无效：参数未定义'/home/integra/public_html/lifeline/billing/resendpdfinvoice.php:94堆栈跟踪：＃0 /home/integra/public_html/lifeline/billing/resendpdfinvoice.php(94）：第94行/home/integra/public_html/lifeline/billing/resendpdfinvoice.php中抛出PDOS方法 - ＆gt;执行（数组）＃1 {main}

我无法弄清楚它有什么问题

Answer 1

where invoice_number = :invoice_number
                               ^---- underscore here

$stmt->execute(array(':invoicenumber' => $_GET["inv"], 
                              ^---no underscore here

Answer 2

见这里

invoicenumber!=invoice_number

Answer 3

当您的执行语句要求:invoice_number时，您的查询似乎包含:invoicenumber。尝试将它们设置为相同的值（例如:invoice_number）

$stmt = $pdo_conn->prepare("select * from billing_pdf_archive"
    . " where invoice_number = :invoice_number and sequence = :sequence ");

$stmt->execute(array(
    ':invoice_number' => $_GET["inv"], 
    ':sequence' => $_GET["seq"]
));
$result = $stmt->fetch();

在PDO中运行SQL查询时出现PDOException错误
