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.
  • The database stores the view definition but not the corresponding data. If a view is accidentally deleted and the base table remains unchanged, you can recreate the view using the CREATE 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.

  • view_name

    Specifies the name of the view to be deleted.

  • CASCADE | RESTRICT
