postgresqlHow do I create a view in PostgreSQL?

To create a view in PostgreSQL, you need to use the CREATE VIEW statement. The syntax of creating a view is as follows:

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

The view_name is the name of the view to be created. The column1, column2, etc. are the columns to be selected from the table_name. The WHERE clause is optional and specifies the conditions that must be met for the records to be included in the view.

For example, to create a view named sales_view from the sales table:

CREATE VIEW sales_view AS
SELECT customer_name, product, quantity
FROM sales
WHERE quantity > 5;

This will create a view that contains the customer_name, product, and quantity columns from the sales table, but only for records where the quantity is greater than 5.
