Updating a view means modifying its underlying SQL query.
Views can be changed when business requirements change.
This helps maintain accurate data presentation.
Views do not store data themselves.
Updating a view changes the query definition, not the actual table data.
The CREATE OR REPLACE VIEW command is used to update an existing view.
This replaces the old view definition.
Updating a view allows adding or removing columns.
The view output changes according to the new query.
This helps keep reports updated.
Updated views immediately reflect changes.
Applications using the view do not need query changes.
This improves maintainability.
