UNION ALL view ‘%.*ls’ is not updatable because a partitioning column was not found.

Error Message:
Msg 4436, Level 16, State 12, Line 1
UNION ALL view ‘%.*ls’ is not updatable because a partitioning column was not found.

Severity level:
16.

Description:
This error message appears when you try to update a UNION ALL view ut no partitioning column was found.

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. You cannot update a UNION ALL view that does not contain a partitioning column.

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

Example(s):
IF OBJECT_ID (‘dbo.T’) IS NOT NULL
    DROP TABLE dbo.T;
GO
IF OBJECT_ID (‘dbo.T1′) IS NOT NULL
    DROP TABLE dbo.T1;
GO
IF OBJECT_ID (‘dbo.V’) IS NOT NULL
    DROP VIEW dbo.V;
GO

CREATE TABLE dbo.T
(
    c1 int PRIMARY KEY
)
GO

CREATE TABLE dbo.T1
(
    c1 int PRIMARY KEY
)
GO

CREATE VIEW dbo.V
AS
SELECT
    c1
FROM
    dbo.T
UNION ALL
SELECT
    c1
FROM
    dbo.T1;
GO
UPDATE dbo.V
    SET
    c1 = 1;

Remarks:
In the above example we try to update the view dbo.V. Because this UNION ALL view contains no partitioning column, the error is raised.
