DBMS_MVIEW.REFRESH is not populating data

edited Jul 18, 2020 5:12AM in Database DataWarehousing (MOSC) 5 commentsAnswered

We are on Oracle Database 12.1.0.2.0 with Editions Enabled. For certain Materialized Views, we are observing that the DBMS_MVIEW.REFRESH is finishing very quickly like 10 seconds and not populating any data into the snapshot table. There are no errors either during the REFRESH command, it complete clean without inserting any data.

What is the reason for this behavior ? Any thoughts ?

Howdy, Stranger!
