note 98038 added to pdostatement.fetchcolumn

Not only you cannot receive another column from the same row, but also it seems you cannot call fetchColumn() more than once:

<?php
$result = $dbconn->query("SELECT product_quantity FROM products WHERE product_id = '1234'");

//this will yield correct result:
echo $result->fetchColumn();

//but this won't
if($result->fetchColumn() > 0){
echo $result->fetchColumn();
}
?>
so you have to assign it to a variable if you want to use it multiple times:

<?php
$quantity = $result->fetchColumn();
?>
