Was just at RPG-DB2 Summit - we are encouraged to put as much into a
single SELECT statement as we can, by the IBMer, Tom McKinley, who did
a presentation on set-based thinking with SQL.

Tom specifically said to avoid multiple steps of putting data into
separate tables in QTEMP. instead, look for ways to combine as JOINs
or maybe as IN predicates against a subquery.


Do common table expressions count as "separate tables"?
