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
