Jul 22, 2024 · This article describes how to create indexes on a view. The first index created on a view must be a unique clustered index. After the unique clustered index has been created, you can create more nonclustered indexes.
To create an indexed view, you use the following steps: First, create a view that uses the WITH SCHEMABINDING option which binds the view to the schema of the underlying tables. Second, create a unique clustered index on the view. This materializes the view.
An indexed view is physically stored ("materialised") on disk = requires memory. A standard view is simply an expandable macro: there is no persistence of the data and the base tables are always used. Other notes: Both will return the correct data from the base tables.
Feb 12, 2014 · Standard SQL Server views can help. When we encapsulate complex multi-table query logic in a view, any application that needs that data is then able to issue a much simpler query against the view, rather than a complex multi- JOIN query against the underlying tables. Views bring other advantages too.
Mar 15, 2019 · I can use sys.dm_db_index_physical_stats to view the depth of the B-tree non-clustered index. Remember that a non-clustered index contains only a subset of the columns in the base table and is organized in a B-tree structure.
Jul 19, 2024 · Indexed views. An indexed view is a materialized view. 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.

Apr 22, 2024 · Index views, known as indexed views in Microsoft SQL Server, are powerful tools for optimizing the performance of complex queries. They are essentially regular views with a unique clustered index, which turns the view into a stored set of results that SQL Server can quickly retrieve.
