Error Message:
Msg 1939, Level 16, State 1, Line 2

Severity level:
16.

USE Northwind;
GO
SET NUMERIC_ROUNDABORT OFF;
SET ANSI_PADDING,
ANSI_WARNINGS,
CONCAT_NULL_YIELDS_NULL,
ARITHABORT,
QUOTED_IDENTIFIER,
ANSI_NULLS ON;
GO
IF OBJECT_ID (‘dbo.MyOrderView’, ‘View’) > 0
DROP VIEW dbo.MyOrderView;
GO
CREATE VIEW dbo.MyOrderView
–WITH SCHEMABINDING
AS
SELECT SUM(UnitPrice*Quantity*(1.00-Discount)) AS Revenue,
OrderDate, ProductID, COUNT_BIG(*) AS MyCount
FROM dbo.[Order Details] AS od
JOIN dbo.Orders AS o
ON od.OrderID = o.OrderID
GROUP BY OrderDate, ProductID;
GO
CREATE UNIQUE CLUSTERED INDEX cix_MyOrderView
ON dbo.MyOrderView (OrderDate, ProductID);
GO
Remarks:
In the above example we try to index the view MyOrderView. Because the view was not created schema-bound, the error is raised.
