Understanding View in SQL: Exploring 2 Ways to Create Views


In the world of SQL, a powerful tool called View exists that simplifies complex queries and enhances the overall efficiency of data retrieval. In this article, we will delve into what is a view in sql the concept of View in SQL and explore two different methods to create views. Whether you’re a seasoned SQL expert or just starting your journey in database management, understanding views can greatly enhance your SQL skills. So, let’s dive in!

What is View in SQL?

At its core, a View in SQL is a virtual table that is dynamically created by a SQL query. It acts as a convenient way to store complex and frequently used queries as a separate entity. Think of it as a shortcut to access specific data without having to write lengthy queries repeatedly. By creating a view, you can simplify your SQL code, enhance data security, and improve overall performance.

Method 1: Creating Views in SQL

The first method to create a view involves using a CREATE VIEW statement in SQL. This method allows you to create a view by specifying the desired columns and tables from which the view will derive its data. Let’s take a closer look at the syntax:ExplainCREATE VIEW view_name AS SELECT column1, column2, ... FROM table_name WHERE condition;

By following this syntax, you can create a view tailored to your specific needs. This method is particularly useful when you want to retrieve data from multiple tables and present it in a unified format.

Method 2: Creating Views with Aliases

The second method involves using aliases to create views. Aliases are alternate names assigned to tables or columns in SQL queries. By utilizing aliases, you can create a temporary view without explicitly using the CREATE VIEW statement. Here’s how this method works:

SELECT column1 AS alias1, column2 AS alias2, ...
FROM table_name
WHERE condition;

By assigning aliases to the columns you select, you effectively create a temporary view that can be used for quick reference and analysis. This method is particularly handy when you want to perform ad-hoc queries without the need for permanent view creation.


In conclusion, understanding the concept of View in SQL is crucial for any data professional looking to optimize their database management skills. We explored the two main methods of creating views: using the CREATE VIEW statement and utilizing aliases. By incorporating views into your SQL workflow, you can simplify complex queries, improve performance, and enhance data security.

As the world of data continues to evolve, mastering SQL and its powerful features like views is essential. So, embrace the power of views, experiment with different approaches, and unlock the full potential of SQL in your data journey.
