----------------------------------------------------------------
Potentially this is across users but, for our use case, the only downside to scoping by user is additional storage requirements.
I hadn't considered using temp tables. I'll reread the docs and think about whether they satisfy our needs.
Thanks

> I'd like to be able to query a dynamically defined materialized view. For example, suppose I issue the query
> /* mat-view */ SELECT * FROM blah WHERE x='abc'
> Optionally (probably based on a hint), I'd like the following query to execute against the data set returned by the previous query rather than going back to the data source:
> /* use-mat-view */ SELECT * FROM (SELECT * FROM blah WHERE x='abc') GROUP BY a
> To make this truly useful, I'd like to define indexes. Something like:
> /* mat-view(index-on:a,b,c) */ SELECT * FROM blah WHERE x='abc'
