PostgreSQL – How to Drop a View

To drop (delete) a view in PostgreSQL, you can use the DROP VIEW statement followed by the name of the view you want to remove. Here’s the basic syntax for dropping a view:

DROP VIEW [IF EXISTS] view_name;

where

  • view_name: The name of the view you want to drop.
  • IF EXISTS (optional): Prevents an error from occurring if the view doesn’t exist. If you use IF EXISTS, PostgreSQL will only drop the view if it exists; otherwise, it will do nothing.

Here’s an example of how to drop a view in PostgreSQL:

DROP VIEW IF EXISTS high_salary_employees;

In this example, we’re attempting to drop a view named “high_salary_employees.” If the view exists, it will be deleted. If it doesn’t exist, no error will be raised.

Make sure to use caution when dropping views, as this operation is irreversible, and it permanently removes the view and its definition. Be certain that you want to delete the view before executing the DROP VIEW statement.
