DROP VIEW

Function

DROP VIEW deletes an existing view.

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.
  • For more information about development and design specifications, see Development and Design Proposal.
