Oracle Error Message
ORA-30355: materialized view container does not exist
Reason for the Error
A DROP TABLE command was issued directly against the materialized view container table.
Solution
Use the DROP MATERIALIZED VIEW command to clean up the residual meta data for the materialized view. Then use the CREATE MATERIALIZED VIEW statement to recreate the materialized view. Thereafter, use the DROP MATERIALIZED VIEW command rather than the DROP TABLE command to drop a materialized view.
