I would create an SQL view (externally) and use that.

Subject: [EXTERNAL] Coding SQL in RPG
Hi,
I have an RPGSQLE programme and I want to code several similar statements.
They have a common WITH expression and only a difference in a GROUP BY
clause :
Exec sql
With t as (
SELECT etc with the same host
variables
)
SELECT etc
FROM t
GROUP BY (clause1 or clause2 ….)
End-exec
What is the best way to code this ? I seem to remember that having several
copies of the statements instead of building them during run time is
actually more efficient.
