Partitioned view ‘%.*ls’ is not updatable because it does not deliver all columns from its member tables.

Error Message:
Msg 4438, Level 16, State 17, Line 2
Partitioned view ‘%.*ls’ is not updatable because it does not deliver all columns from its member tables.

Severity level:
16.

Description:
This error message appears when you try to insert into or update a partitioned view that does not expose all columns from its member tables.

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. The partitioned vliew must expose all columns from its member tables.

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 CHECK (c1 BETWEEN 1 AND 10),
    c2 int 
)
GO
CREATE TABLE dbo.T1
(
    c1 int PRIMARY KEY CHECK (c1 BETWEEN 11 AND 20),
    c2 bit
)
GO

CREATE VIEW dbo.V
AS
SELECT
    c1
FROM
    dbo.T
UNION ALL
SELECT
    c1
FROM
    dbo.T1
GO

INSERT INTO dbo.V (c1) VALUES (1);

Remarks:
In the above example we try to insert into the view dbo.V. Because dbo.V does not expose the column c2 from its member tables, the error is raised.
