Since SQL Server 2016 (13.x) Service Pack 1, all editions support automatic use of an indexed view. Azure SQL Database and Azure SQL Managed Instance also support automatic use of indexed views without specifying the NOEXPAND hint. For more information, see Table Hints (Transact-SQL)....
SQL Server视图索引(Indexed Views): 文章分类:数据库 正如第27章所讲的那样,SQL Server2000允许你创建索引视图。一个索引的视图是任意在其上定义了聚集索引的视图。当一个CREATE INDEX语句在视图上执行时,视图的结果集在数据库中的组织和存储与具有聚集索引的数据表是一样的。 视图中数据表上的数据发生改变将会自...

you must use theNOEXPANDquery hint to query the indexed view directly. Since SQL Server 2016 (13.x) Service Pack 1, all editions support automatic use of an indexed view. Azure SQL Database and Azure SQL Managed Instance also support automatic use of indexed views without specifying theNOEXPAN...
Indexed views in SQL Server are, as near as makes no difference, what's called materialized view elsewhere. If your view has an underlying query that uses indexes defined on the base tables, the select on the view will use the index as well, that's not what an indexed views are about...

第2时期——在这个最后时期优化器全力以赴(pulls out all the stops)使用它所有的优化规则。它同样也会找下并行(parallelism)和索引视图(indexed views)(如果你运行的是企业版(Enterprise Edition))。 第2时期的完成是找到计划的成本对优化需要的时间之间的平衡。在这个时期生成的计划有完全级别(level of "Full")...
SQL Server automatically maintains indexed views similar to any other index. In the case of ordinary indexes, each index is tied directly to a single table. With each INSERT, UPDATE, or DELETE operation performed on the underlying table, the index is updated accordingly so that the values store...
