What is an indexed view SQL?
An indexed view has a unique clustered index. The unique clustered index is stored in SQL Server and updated like any other clustered index. An indexed view is more significant compared to standard views that involve complex processing of large numbers of rows, such as aggregating lots of data, or joining many rows.
What is the use of indexed views in SQL Server?
Creating a unique clustered index on a view improves query performance because the view is stored in the database in the same way a table with a clustered index is stored. The query optimizer may use indexed views to speed up the query execution.
What are SQL Azure capabilities?
SQL Azure is Microsoft’s cloud database service. SQL Azure supports SQL Server’s Transact-SQL (T-SQL) query language, offers built-in support for high availability and fault tolerance and allows for data to be synchronized between on-premises SQL Server and cloud databases.
What is the difference between Azure SQL and SQL Database?
Azure SQL Database offers Database-as-a-service (DBaaS-PaaS). With SQL Database, you don’t have access to the machines that host your databases. In contrast, Azure Virtual Machine offers Infrastructure-as-a-service (IaaS). Running SQL Server on an Azure VM is similar to running SQL Server in a On-Premise datacenter.
What does indexed view mean in SQL Server?
An indexed view is a view that has been materialized. This means the view definition has been computed and the resulting data stored just like a table. You index a view by creating a unique clustered index on it. Indexed views can dramatically improve the performance of some types of queries.
What are the features of Azure SQL database?

How to prevent the database engine from using indexed views?
Indexed views can be created on a partitioned table, and can themselves be partitioned. To prevent the Database Engine from using indexed views, include the OPTION (EXPAND VIEWS) hint on the query. Also, if any of the listed options are incorrectly set, this will prevent the optimizer from using the indexes on the views.
