SQL - VIEWS

The SQL VIEW statement is used to create a SQL VIEW which is a virtual table created based on the SQL statement. A view contains rows and columns just like a normal table. All SQL functions, WHERE, HAVING and JOINs statements can be used to create a SQL VIEW.

Syntax

The syntax for using SELECT statement in different scenarios are given below:

CREATE VIEW view_name AS
SELECT column1, column2, column3, ...
FROM table_name
WHERE condition(s);

Example:

Consider a database table called Employee with the following records:

The below mentioned SQL statement is used to create a view on Employee table which contains all records of employee whose salary is greater than 2800.

CREATE VIEW [Employee Salary GT 2800] AS
SELECT * FROM Employee WHERE Salary > 2800;

After creating the VIEW, it can be used as mentioned below:

SELECT * FROM [Employee Salary GT 2800];

This will produce the result as shown below:
