SQL & PL/SQL

Is there a way to limit the length of the result of LISTAGG()?

I have two reasons for that:
- VARCHAR2 limit of 4000 bztes
- I only need the first 10 elements (rows)

The query I use is:

select count(order_id) numOfOrders, order.store_id,  store.PhoneNr,
	  LISTAGG( order_Id, ', ' ) WITHIN group ( ORDER BY Order_Id)  as first_ten_orders
	from t_orders order
	inner join store on store.store_id=order.store_id and (store.PhoneNr is not null )
	where order_status_id in (1,2,6) and order_date!=shipped_date
	group by order.store_id, store.PhoneNr;

So it is a list of non shipped orders, grouped by stores (only those with phone numbers), listing the store ID, phone number, number of unshipped orders and the list of order IDs.

I want to limit the list of order IDs, for example to first ten items.

How can I do that?

One way is to use a (custom) function to trim the result string, but then I would still have the first problem of VARCHAR2 length overflow in case of many orders.
