If you check the above query it just selects query and if you want to get data from the view you will able to treat it as a table and simple select * from view_name; by using this you can get data.

View doesn’t store any data and it is just saved select query.

Advantages of views

  1. It is used to reduce the complexity of database schema
  2. It provides a mechanism to implement column level and row-level security means if you want to give access to certain users with a limited number of rows and columns then put your query in view and given that view name to end-user so that he performs the operation on that considering this is a table.
