Cannot create %S_MSG on view ‘%.*ls’ because its select list does not include a proper use of COUNT_BIG. Consider adding COUNT_BIG(*) to select list.

Error Message:
Msg 10138, Level 16, State 1, Line 2
Cannot create %S_MSG on view ‘%.*ls’ because its select list does not include a proper use of COUNT_BIG. Consider adding COUNT_BIG(*) to select list.

Severity level:
16.

Description:
This error message appears when you try to use an aggregate function in an indexed view, without using the COUNT_BIG(*).

Consequences:
The SQL statement cannot be parsed and further execution is stopped.

Resolution:
Errors 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. Indexed views using an aggregate functions must also use the COUNT_BIG(*) function.

Versions:
This error message was introduced with SQL Server 2000.

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(UnitPrice*Quantity*(1.00-Discount)) AS Revenue,
    OrderDate, ProductID
  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 use SUM() aggregate function in an indexed view. Because we don’t also use the COUNT_BIG(*) function, the error is raised.
