Show me the order with shipment tracking number 3452.
select * from orders as t1 join shipments as t2 on t1.order_id = t2.order_id where shipment_tracking_number = 3452
When was that order placed?
select t1.date_order_placed from orders as t1 join shipments as t2 on t1.order_id = t2.order_id where t2.shipment_tracking_number = 3452
