Just seen Kent Milligan's excellent tips regarding the use of QTEMP with SQL

https://www.mcpressonline.com/analytics-cognitive/db2/techtip-top-3-reasons-to-avoid-mixing-sql-with-qtemp

I wonder why not also use the With clause
like

with tt as (select Cust_Id, sum(Ord_Amount) as OrdAmount from cust_ord group
by Cust_Id ) select tt.Cust_Id, Custfile.CustName, tt.OrdAmount from tt
left outer join Custfile on Custfile.Cust_Id = tt.Cust_Id
What am I missing/misunderstanding ?

TIA
Gad
