Also asked, can you index a view in SQL?
SQL Server indexed views. To enhance the performance of such complex queries, a unique clustered index can be created on the view, where the result set of that view will be stored in your database the same as a real table with a unique clustered index.
Likewise, what happens when you index a view? Views allow you to create a virtual table by defining a query against one or more tables. With a standard view, the result is not stored in the database. Instead, the result set is determined at the time a query utilizing that view is executed.
Just so, can a view have an index?
The first index created on a view must be a unique clustered index. 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.
