Have you used virtual tables in your SQL queries?

Virtual tables in SQL are usually understood as views — saved queries that behave like tables when accessed. I used them to simplify complex queries and improve code readability. For example, if you often need to retrieve combined data from multiple tables, you can create a view:

CREATE VIEW active_users AS
SELECT id, name, email FROM users WHERE status = 'active';

After that, you can access active_users as a regular table, which simplifies queries and increases code reuse.
