如何从$ query获取 stName 的结果到UPDATE语句的 stName =？

我想获取随机记录并将其标记为“Y”以显示它已被查看。

$query = $conn_db->prepare('SELECT stName, subject FROM my_db WHERE status = ? ORDER BY RAND() LIMIT 1');
$array = array('N');
$query->execute($array);
$result = $query->fetchAll(PDO::FETCH_ASSOC);
var_dump($result);


$status = 'Y';
$sql = 'UPDATE my_db SET status=? WHERE stName=?';
$q = $conn_db->prepare($sql);
$q->execute(array($status,$result));
