Indexed Views
Save
Indexed views are a powerful tool that can improve the performance of your SQL Server database. They can be used to speed up queries that access large tables or that involve complex joins. Indexed views can also be used to improve the security of your database by providing a way to restrict access to certain data.
How Indexed Views Work
Indexed views are created by using the CREATE VIEW statement. The CREATE VIEW statement takes two arguments: the name of the view and the query that defines the view. The query that defines the view can be any valid SQL statement. However, it is important to note that the query must be deterministic, meaning that it will always return the same results for the same input data.
Once a view has been created, it can be used in any SQL statement as if it were a table. However, indexed views are not actually stored in the database. Instead, they are generated on the fly when they are accessed. This means that indexed views can be used to improve the performance of queries without taking up any additional storage space.
Benefits of Using Indexed Views
There are many benefits to using indexed views. Some of the benefits include:
- Improved query performance
- Reduced storage space
- Improved security
- Simplified data access

- Connect to the database in which you want to create the view.
- Right-click on the database and select
New>View. - In the
View Designer, enter the name of the view and the query that defines the view. - Click on the
Indexestab and select the columns that you want to index. - Click on the
OKbutton to create the view.
