The following steps are required to create an indexed view and are critical to the successful implementation of the indexed view: Verify the SET options are correct for all existing tables that will be referenced in the view. Verify that the SET options for the session are set correctly before you From Views to Indexed Views Create a View. Listing 2 creates a view based on our query definition, as shown in Listing 2. Create a Unique, Clustered Index. Before we start, I should mention that there are a host Aggregating Data with Indexed Views. Indexed views can really come into their Unlike regular views, indexed views are materialized views that stores data physically like a table hence may provide some the performance benefit if they are used appropriately. To create an indexed view, you use the following steps: Creating indexed views differs from creating normal views in that using the SCHEMA BINDING hint is not optional. This means that you will not be able to apply structure changes on the tables that may affect the indexed view unless you alter or drop that indexed view first.

A view created with a unique clustered index is known as an “Indexed View” or “Materialized View”. Unlike views, an Indexed View exists on the disk like a table in which the clustered index is created. Once a clustered index is created you may create non-clustered indexes on the view. As said earlier, Indexed Views exist on the disk How to create indexed views. To create an indexed view, just create an unique clustered index on the view. As and when you will create an unique clustered index on the view, it’s data gets materialized in the database. Here I am taking “AdventureWorks2012” as a database to demonstrate my example and below is the definition of the view.

The unique clustered index is stored in SQL Server and updated like any other clustered index. 12 Feb 2014 Let's see what happens, however, if we turn our standard view into an indexed view. Create a Unique, Clustered Index. Before we start, I should  19 Nov 2013 The view definition can reference one or more tables in the same database. Once the unique clustered index is created, additional nonclustered 

An indexed view will cause the same issues as an index on the column, because indexed views require with schemabinding, which tie it to the table directly, disallowing you from changing/altering the schema of that table in any way, shape, or form.

Where to Use Indexed View When you use the same complex query on many tables, multiple times. When new system need to read old table data, but doesn't watch to change their perceived schema. The environments that are best suited for indexed views are data warehouses, data marts, OLAP databases but A view created with a unique clustered index is known as an “Indexed View” or “Materialized View”. Unlike views, an Indexed View exists on the disk like a table in which the clustered index is created. Once a clustered index is created you may create non-clustered indexes on the view. As said earlier, Indexed Views exist on the disk like a table. So each time the source table is updated, then the view gets updated, and the indexes are recompiled. An indexed view is a view that has been materialized or stored in the database. The index that is created on the view is stored and updated by the database engine as the underlying table is updated. Indexed views work great for situations where your result set returns a lot of rows and needs to be aggregated. Indexed views have both a benefit and a cost. The cost of an indexed view is on the maintenance of the clustered index (and any non-clustered indexes you may choose to add). One must weigh the cost to maintain the index against the benefit of query optimization provided by the index. When indexed views help, they make aggregation queries super fast. There are some kind of horrible limitations and requirements. When they hurt, your modifications slow to a crawl because SQL has to not only keep your horrible indexes synchronized, it also has to keep your indexed view indexes in sync now, too.
