无法在视图“View_Table_Name”上创建索引，因为视图不是架构绑定的 [英] Cannot create index on view 'View_Table_Name' because the view is not schema bound

问题描述

我在存储过程（SQL-Server）中使用了Views。为了提高性能，我尝试创建该视图的INDEX。

I am using Views in my stored Procedure(SQL-Server). For Improving Performance, I have tried to created INDEX of that View.

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER VIEW VW_Table_Name
AS
SELECT Col1,Col2,Col3 FROM Table_Name 
GO
CREATE UNIQUE CLUSTERED INDEX Index_Name ON [VW_Table_Name](Col1)
GO

这里我得到错误

Msg 1939，Level 16，State 1，Line 1
无法在视图'VW_FML'上创建索引，因为视图不是模式绑定的。

Msg 1939, Level 16, State 1, Line 1 Cannot create index on view 'VW_FML' because the view is not schema bound.

我们可以在SQL Server中为View创建索引吗？

Can we created Index for View in SQL Server ?

推荐答案

索引视图有许多限制：没有子查询，没有联合，没有外连接等。请参阅本文了解更多详情。但是对于您的情况，您只需要使用模式绑定创建视图。

There are a number of restrictions on indexed views: no subqueries, no unions, no outer joins, etc. See this article for more details. But for your case, you simply need to create the view with schema binding.

CREATE VIEW VW_Table_Name WITH SCHEMABINDING
AS
SELECT Col1,Col2,Col3 FROM Table_Name 
GO
