Error Message:
Msg 1959, Level 16, State 1, Line 2
Cannot create an index on a view or computed column because the compatibility level of this database is less than 80. Use sp_dbcmptlevel to raise the compatibility level of the database.
Severity level:
16.
Description:
This error message appears when you try to create an indexed view that is contained in a database with a compatibility level less than 80.
Consequences:
The T-SQL statement can be parsed, but causes the error at runtime.
Resolution:
Error of the Severity Level 16 are generated by the user and can be fixed by the SQL Server user. The statement cannot be executed this way. To index a view the compatibility level of the database must be at least 80 (or higher).
Versions:
All versions of SQL Server /(beginning with SQL Server 2000).
Example(s):
USE Northwind;
GO
EXEC sp_dbcmptlevel ‘Northwind’, ’70’
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 CLUSTERED INDEX cix_MyOrderView
ON dbo.MyOrderView (OrderDate, ProductID);
GO
EXEC sp_dbcmptlevel ‘Northwind’, ’70’
GO
Remarks:
In the above example we lower than compatibility level of the Northwind database to 70. When trying now to create an indexed view, the error is raised.
