Well, I have a situation where an Order object holds a collection of
LineItem objects and of course they all use the same DB connection via a
singleton.
The Order object has a method that creates new LineItem objects from an
ORDER_DTL table.
Code snippet:
// SET ORDER ITEMS
$stmt = $this->db->prepare($detailSQL);
$stmt->execute(array(':orderid' => $orderID));
while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
$lineItem = new GCLineItem($row['item_id']);
$lineItem->__set('quantity', $row['quantity']);
$lineItem->__set('price', $row['price']);
$this->items[] = $lineItem;
}
Within the while loop I am loading GCLineItem objects that themselves
try to create a statement object which is where the error is triggered
since both share the same DB connection and the statement objects trip
over themselves.
I get an SQL error HY090 Buffer error...
My only solution was to let the GCLineItem objects create another DB
connection for themselves. This is not ideal and is a hack in my
opinion.
I could run a fetchAll on the Order statement object and this would
complete one statement object before each GCLineItem objects creates
there own statement object - correct? I may have just answered my own
question, but if you or anybody else can think of a better solution - I
am all ears!

There's no reason why it can't. However, if any of those queries fail
the whole transaction will get rolled back.
What errors are you getting?
