Error Message:
Msg 4511, Level 16, State 1, Procedure MyOrderView, Line 4
Create View or Function failed because no column name was specified for column %d.
Severity level:
16.
Description:
This error message appears when you try to create a view without providing unambiguous column names for all columns.
Consequences:
The T-SQL statement can be parsed, but causes the error at runtime.
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. All columns in a view definition must have a unambiguous name.
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(UnitPrice*Quantity*(1.00-Discount)) AS Revenue,
OrderDate, ProductID, COUNT_BIG(*)
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 create the indexed view MyOrderView. The view uses the aggregate function COUNT_BIG(*) withoutr providing an alias for the column. This raises the error.
