Eliminate Redundant Views from Your Database

Drop a View

Write a PostgreSQL query to drop an existing view that is no longer needed.

Solution:

-- Drop the EmployeeInfo view if it exists.
DROP VIEW IF EXISTS EmployeeInfo;

Explanation:

• Purpose of the Query:
• The goal is to remove a view that is obsolete or no longer required.
• This demonstrates how to safely drop a view using the IF EXISTS clause.
• Key Components:
• DROP VIEW IF EXISTS : Ensures that the command does not error out if the view is missing.
• EmployeeInfo : The name of the view to be dropped.
• Real-World Application:
• Helps in maintaining a clean database schema by removing redundant objects.

Notes:

• Dropping a view does not affect the underlying tables or data.
