Question

我正在运行一个一直运行良好的脚本，最后一次运行昨天，现在我在运行它时遇到了这些错误：

常规错误：0 [IBM] psystem i访问odbc驱动程序]未定义变量：detailCheck调用null
上的成员函数fetch（）

所有人都在同一条线上：

while ($row2 = $detailCheck->fetch(PDO::FETCH_ASSOC)) {

同样，它工作正常，连接良好，表存在，查询全部手动运行。我没有做任何改变，所以我完全迷失在这里

$ordStatSql = 'SELECT order_id, order_status, is_placement, date_updated 
            FROM order_status
            WHERE order_status = "S"
            AND date_updated IS NULL';
try{
$ordStat = $MysqlConn->prepare($ordStatSql);
$result = $ordStat->execute();
}
catch(PDOException $ex)
{
echo "QUERY FAILED!: " .$ex->getMessage();
}

$order_ids = [];
while ($row = $ordStat->fetch(PDO::FETCH_ASSOC)) {
$order_ids[] = $row['order_id'];
}

if (count($order_ids) > 0) {

$placeholders = implode(',', array_fill(0, count($order_ids), '?'));
$detailStatCheck = "
    SELECT 
         invnoc as INVOICE,
         fstatc as STATUS,
         cstnoc AS DEALER,
         framec AS FRAME,
         covr1c AS COVER,
         colr1c AS COLOR ,
         extd2d AS SHIPDATE,
         orqtyc AS QUANTITY
    FROM GPORPCFL
    WHERE invnoc IN ($placeholders)
";

try {
    $detailCheck = $DB2conn->prepare($detailStatCheck);
    $detailRslt = $detailCheck->execute($order_ids);
    $count2 = $detailCheck->fetch();
    print_r($order_ids);
    print_r($count2);
} catch(PDOException $ex) {
    echo "QUERY FAILED!: " .$ex->getMessage();
}

//the below 'while' line is where I get the error
while ($row2 = $detailCheck->fetch(PDO::FETCH_ASSOC)) {

    $values = [
        ":DEALER" => $row2["DEALER"],
        ":SHIPDATE" => $row2["SHIPDATE"],
        ":QUANTITY" => $row2["QUANTITY"],
        ":INVOICE" => $row2["INVOICE"],
        ":FRAME" => $row2["FRAME"],
        ":COVER" => $row2["COVER"],
        ":COLOR" => $row2["COLOR"],
    ];

    $values2 = [
        ":DEALER" => $row2["DEALER"],
        ":FRAME" => $row2["FRAME"],
        ":COVER" => $row2["COVER"],
        ":COLOR" => $row2["COLOR"],
        ":INVOICE" => $row2["INVOICE"],

    ];

Db2和mysql上的PDO，调用null
