Views in MySQL

What is a View?

A view is a saved query that behaves like a virtual table. It does not store data itself — it shows live data from the underlying tables each time you query it.

Creating a View

CREATE VIEW toppers AS
SELECT name, marks FROM students WHERE marks >= 90;

-- use it like a table
SELECT * FROM toppers;
Every time you query "toppers", it runs the saved SELECT on current data.

Why Use Views?

  • Hide complex joins behind a simple name.
  • Show users only certain columns (security).
  • Reuse a common query everywhere.

Removing a View

DROP VIEW toppers;

Summary

  • A view is a saved query acting as a virtual table.
  • It stores no data; it shows live results from base tables.
  • Good for simplifying queries and limiting access.
