Error Message:
Msg 1947, Level 16, State 1, Line 2
Cannot create %S_MSG on view “%.*ls”. The view contains a self join on “%.*ls”.

Severity level:
16.

Description:
This error message appears when you try to create an indexed view that contains a self-join.

Consequences:
The T-SQL statement can be parsed, but causes the error at runtime.

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. The self-join must be removed.

Versions:
All versions of SQL Server.

Example(s):
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(od.UnitPrice*od.Quantity*(1.00-od.Discount)) AS Revenue,
    o.OrderDate, od.ProductID, COUNT_BIG(*) AS MyCount
  FROM dbo.[Order Details] AS od
  JOIN dbo.Orders AS o
    ON od.OrderID = o.OrderID
    JOIN dbo.Orders t1
      ON o.OrderID = t1.OrderID
 GROUP BY o.OrderDate, od.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 this view contains a self-join on the table Orders, the error is raised.
