Create View
In SQL, a view is a virtual table based on the result set of an SQL statement.
The CREATE VIEW command creates a view.
The following SQL creates a view that selects all customers from Brazil:
Example
CREATE VIEW [Brazil
Customers] AS
SELECT
CustomerName, ContactName
FROM Customers
WHERE
Country = "Brazil";Query The View
We can query the view above as follows:
Example
SELECT * FROM [Brazil
Customers];Create Or Replace View
The CREATE OR REPLACE VIEW command updates a view.
The following SQL adds the "City" column to the "Brazil Customers" view:
Example
CREATE OR REPLACE VIEW [Brazil Customers] AS
SELECT CustomerName, ContactName, City
FROM Customers
WHERE Country = "Brazil";Drop View
The DROP VIEW command deletes a view.
The following SQL drops the "Brazil Customers" view:
Example
DROP VIEW [Brazil Customers];
