cannot set the ON COMMIT refresh attribute for the materialized view

This ORA-12054 error is related with the materialized view did not satisfy conditions for refresh at commit time.

Specify only valid options.

 

If you use the DISTINCT keyword in Materialized View, You will get this error.

So don’t use the DISTINCT keyword in Materialized View query. You can use Group By instead of distinct.

If you use JOIN in your query, you will get this error. You should use the old Join like A, B tables

 where A.ID = B.ID

 

Materalized views support only SUM, COUNT, AVG, STDDEV, VARIANCE, MIN and MAX for fast refresh.
