How to create a view with parameters in Oracle?

In Oracle, creating parameterized views can be achieved by creating stored procedures with parameters. Here’s an example:

CREATE OR REPLACE VIEW my_view (
    parameter1, 
    parameter2
) AS
SELECT column1, column2
FROM my_table
WHERE column3 = parameter1
AND column4 = parameter2;

In this example, my_view is a view with two parameters, parameter1 and parameter2, that selects data from the my_table table based on predefined conditions. When using this view, you can input different parameter values to obtain various outcomes.

To use a view with parameters, you can simply provide the appropriate parameter values just as you would with a regular view.

SELECT * FROM my_view('value1', 'value2');

This will return the data that meets the criteria column3 = ‘value1’ and column4 = ‘value2’.
