Cannot create index on view ‘View_Table_Name’ because the view is not schema bound

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

Here I am getting the Error like

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

Can we created Index for View in SQL Server ?

Answer

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
