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 that was created FOR FAST REFRESH, 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.

See Also:

Oracle Database Data Warehousing Guide for a description of these types of materialized views

After you drop a materialized view log that was created FOR SYNCHRONOUS REFRESH (a staging log), the materialized views based on the staging log master table can no longer be synchronous refreshed.

Examples
