无法在视图“View_Table_Name"上创建索引，因为该视图未绑定架构

问题描述

我在存储过程(SQL-Server)中使用视图.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

这里我收到了类似的错误

Here I am getting the Error like

消息 1939，级别 16，状态 1，第 1 行无法在视图VW_FML"上创建索引，因为该视图未绑定架构.

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 中为视图创建索引吗?

Can we created Index for View in SQL Server ?

推荐答案

索引视图有很多限制:没有子查询、没有联合、没有外连接等.参见 这篇文章 了解更多详情.但对于您的情况，您只需要创建具有架构绑定的视图.

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
