Folks,

we have a very complex view that gets executed every night and takes nearly 3 hours to complete. The view has several outer joins, decodes, NVLs and subqueries referencing several tables. I understand we cannot convert complex view into Fast Refereshed Materialized view. Has anyone come up with an alternative approach?

I would like to see this view fast Refreshed and not take 3 hours to do complete refresh. Any suggestions?

Thanks

Hi,

You can solve this problem by creating several materialized views on the required base tables. After that, create your view on top of the materialized views.

Best regards.
