In this regard, can you create an index on updatable views?

Indexed views can be a powerful tool, but they are not a 'free lunch' and we need to use them with care. Once we create an indexed view, every time we modify data in the underlying tables then not only must SQL Server maintain the index entries on those tables, but also the index entries on the view.

Beside above, is it possible to create an index on views in Oracle? A view does not actually contain data, but just a SQL statement to get data from one or more tables. Some systems will let you create an index on the view so that selecting data from the view will be faster. Oracle databases do not support indexing views. But Oracle does support a Materialized View (MV).

Then, how do you create an index on a view in SQL Server?

To create an indexed view, you use the following steps:

1. First, create a view that uses the WITH SCHEMABINDING option which binds the view to the schema of the underlying tables.
2. Second, create a unique clustered index on the view. This materializes the view.

Can we create nonclustered index on view in SQL Server?

The view definition can reference one or more tables in the same database. Once the unique clustered index is created, additional nonclustered indexes can be created against the view. You can update the data in the underlying tables – including inserts, updates, deletes, and even truncates.
