Recipe Objective - SQL VIEW - How to Create a VIEW in SQL? 

If you're working with databases, you've likely encountered the concept of SQL views. Views in SQL provide a powerful way to simplify complex queries, enhance data security, and improve overall database management. Check out this recipe to explore the ins and outs of creating SQL views, step by step.

What is a SQL View?

In SQL, a view is a virtual table based on the result of a SELECT query. It doesn't store the data itself but presents a logical representation of the data stored in one or more tables. Views can be used to simplify complex queries, encapsulate business logic, and control access to sensitive information.

How to Create a VIEW in SQL? 

Creating a view in SQL involves a straightforward process. Let's break it down into clear steps:

Step 1: Understanding the SELECT Statement

Before creating a view, you need to formulate the SELECT statement that defines the data you want the view to display. This statement can include various clauses like WHERE, JOIN, GROUP BY, and ORDER BY to tailor the view to your specific requirements.

Step 2: Syntax for Creating a View

The basic syntax for creating a view in SQL is as follows:

Syntax:
CREATE VIEW view_name AS
SELECT column_name1, column_name2, ...
FROM table_name WHERE condition;

Step 3: Example: Creating a View Query in SQL 

Let us create a view of customer_id and customer_name of the customers who live in England.

Code:

-- creating a view

CREATE VIEW cust_england AS

SELECT customer_id, customer_name

FROM customers WHERE country="England";

-- retrieving data from the view

SELECT * FROM cust_england;
