Projection with a "WITH" sql clause!

Hi Experts!
Is is possible to create a projection with a WITH clause of sql?
something like this:
CREATE PROJECTION Orders_with_regtime AShttps://omegle.onl/
(WITH
registered as (
select min(time) as first_order_time,OrderId from orders group by OrderId),
orders as
(select OrderId,time,C,D,E,F,G,H,I,J from orders)
select orders.OrderId,time,C,D,E,F,G,H,I,J,registered.first_order_time
from registered,orders where
registered.OrderId=orders.OrderId order by registered.first_order_time desc
