Create Materialized view which refresh records on daily

Question

Currently the Materialized view which I had created using REFRESH ON DEMAND so in this case I need to refresh MV explicitly using below command:

BEGIN DBMS_MVIEW.REFRESH('MV_DATA'); END; 

But now I need to refresh this MV on daily basis so could anyone please help to write this. I have seen that we can refresh this MV using writing explicit Job or using COMPLETE/FAST REFRESH statement in MV itself.

Thanks in advance!

Answer 1

You need to create the materialized view using START WITH and NEXT Clause

create materialized view <mview_name>
refresh on demand 
start with sysdate next sysdate + 1
as select ............

So if you want to refresh mview daily, you need to keep it refresh on demand and set the next refresh time as sysdate + 1. You can set any interval although.

Once you do this the materialized view is created and a job is set in Oracle that will refresh mview every 24 hrs (sysdate + 1).
