Materialized view with Parameter?

[MCMartin]

Is it possible to create a materialized view which uses a parameter during manual refresh? Something like

CREATE MATERIALIZED VIEW "DBA"."MyView" in system as 
select * from X where X.date > PARAM

So that e.g. each week the materialized view can be refreshed to reflect the values of last week or so...

I guess you do not want to use an ordinary view (e.g. something like

select * from x where datediff(dd, x.date, current date) >= 7

for performance reasons. May a global shared by all temporary table be of help? (I'm aware that temporary tables do not get used by view matching.)

(That would better asked as a separate question...): No, materialized views were introduced in v10.

No, not at this time.

Am I right that a (CREATE) VARIABLE won't do, either, as it is connection-specific by default, and that would be non-deterministic, too?

(I'm asking as using such a variable would be a common way to parametrize a normal view.)
