Dropping Views in SQL

Syntax

DROP VIEW view_name;

Example

DROP VIEW customers_view;

Output

This statement will drop the view named customers_view from the database.

Explanation

A view is a virtual table in a database. View contains no data itself, but it shows data from other tables. When a view is no longer needed, it can be dropped using the DROP VIEW statement. Once a view is dropped, the query that referred to the view will not produce results.

Use

Dropping a view is useful when is no longer needed or it needs to be recreated.

Important Points

• Dropping a view will remove the query from the database.
• Views that depend on the view being dropped will also be removed.
• Dropping a view will not affect the data stored in the underlying tables.

Summary

Dropping a view is a simple process that removes the view from the database. It is important to ensure that the view is no longer needed before dropping it. Views are virtual tables that contain no data and are useful when combining data from multiple tables.
