How to delete a view in SQL

The view is a virtual table created based on the table and does not contain the actual data. To delete a view, you can use the following methods:

Steps:

1. Connect to the database: Connect using SQL client or command line to the database.
2. Switch to the schema of the view to be deleted: Use the USE statement to switch to the schema containing the view to be deleted.
3. Delete a view: Delete a view using the DROP VIEW statement followed by the view name.

Syntax:

DROP VIEW <视图名称>;

Example:

To delete the view named SalesView View, you can use the following statement:

USE Sales;
DROP VIEW SalesView;

Note:

• Once the view is deleted, it cannot be restored.
• You cannot delete a view if it is being used by other objects (such as stored procedures or triggers). You need to delete the objects that depend on the view first.
• Views can be recreated as long as the underlying tables still exist.
