Semantics
schema
Specify the schema containing the materialized view log and its master table. If you omit schema
, then Oracle Database assumes the materialized view log and master table are in your own schema.
table
Specify the name of the master table associated with the materialized view log to be dropped.
After you drop a materialized view log, some materialized views based on the materialized view log master table can no longer be fast refreshed. These materialized views include rowid materialized views, primary key materialized views, and subquery materialized views.
