Question

In an SQL view, are the values always changeable through the view itself?
1) Yes
2) No

Answer 1

The values in an SQL view are not always changeable through the view itself.

Step-by-step explanation:

In an SQL view, the values are not always changeable through the view itself. The purpose of a view in SQL is to provide a virtual table that is based on the result of a query. When you query a view, you are retrieving data from the underlying tables it is based on. If you want to modify the data, you would need to modify the underlying tables directly, not the view itself.

For example, if you have a view called 'Employees_View' that is based on a table called 'Employees', any changes made to 'Employees_View' will actually modify the 'Employees' table. Conversely, if you modify the 'Employees' table, the changes will be reflected in the 'Employees_View'. So, while you can query data from a view, any modifications must be made to the underlying tables.

Therefore, the correct answer is No.
