Oracle Create View Method: Syntax & Example

The method for creating a view in Oracle database is as follows:

1. A view can be created using the CREATE VIEW statement with the following syntax.

CREATE VIEW view_name AS
SELECT column1, column2, ...
FROM table_name
WHERE condition;

1. Create a view called employee_view which displays the id, name, and salary fields from the employee table.

CREATE VIEW employee_view AS
SELECT id, name, salary
FROM employee;

1. When creating views, you can manipulate and filter data using aliases, calculated fields, aggregate functions, and more.
2. After creating the view, you can retrieve data by querying the view using the SELECT statement, just like querying a regular table.

SELECT * FROM employee_view;

1. You can use the ALTER VIEW statement to change the definition of a view, and use the DROP VIEW statement to delete a view.
