This topic describes how to create an indexed view in SQL Server 2012 by using Transact-SQL. The first index created on a view must be a unique clustered index. After the unique clustered index has been created, you can create nonclustered indexes. Creating a unique clustered index on a ...
(expression) and COUNT_BIG(expression). For example, an indexed view SELECT list cannot contain the expression AVG(column1). If the view SELECT list contains the expressions SUM(column1) and COUNT_BIG(column1), SQL Server can calculate the average for a query that references the view and ...
Besides the standard role of basic user-defined views, SQL Server provides the following types of views that serve special purposes in a database.Indexed viewsAn indexed view is a materialized view. This means the view definition has been computed and the resulting data stored just like a ...
