Views in SQL | types of views in sql "Hello and welcome to this video on views in SQL. In this video, we will be discussing what views are in SQL, the different types of views, and their advantages.

Views in Oracle can be created using the CREATE VIEW statement. Now, the big question is, what is the advantage of views and why should we create them in SQL? Views provide a number of benefits such as simplifying complex queries, providing security by restricting access to sensitive data, and improving performance by reducing the number of database operations required to generate a result set. In this video, we will also be explaining how to create a view in SQL. Additionally, we will cover the three types of views in SQL, including simple views, complex views, and materialized views. By the end of this video, you will have a solid understanding of what views are, the advantages they provide, and how to create them in SQL. So, let's get started!"
