DROP VIEW

Function

DROP VIEW forcibly deletes an existing view in a database.

Precautions

Only a view owner or a system administrator can run DROP VIEW command.

• Be cautious when using DROP OBJECT (e.g., DATABASE, USER/ROLE, SCHEMA, TABLE, VIEW) as it may cause data loss, especially with CASCADE deletions. Always back up data before proceeding.
