SQL Views

A view in SQL is a virtual table that is based on the result of a SELECT statement. Views provide a way to encapsulate complex queries and reuse them throughout an application, without having to repeat the underlying SQL code.

Here’s an example of how to create a view that returns information about cars with a particular manufacturer:

In this example, we’re creating a view named cars_by_manufacturer that returns information about cars made by the manufacturer ‘Toyota’. The view is based on the SELECT statement that returns the columns manufacturer, model, year, and price from the cars table.

To query the view, you can use the view name in a SELECT statement, just like you would with a table:

This will return the information about all cars made by the manufacturer ‘Toyota’ that are stored in the view.
