Update or insert of view or function '%.*ls' failed because it contains a derived or constant field.

Error Message:
Msg 4406, Level 16, State 1, Line 1
Update or insert of view or function ‘%.*ls’ failed because it contains a derived or constant field.

Severity level:
16.

Description:
This error message appears when you try to insert or update through a view or a function that contains a derived or constant field.

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 insert or update a view or a function that contains a derived or constant field.

Versions:
All versions of SQL Server.

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

CREATE TABLE dbo.T
(
    c1 int
)
GO
CREATE VIEW dbo.V
AS
SELECT
    c1
FROM
    dbo.T
UNION ALL
SELECT
    1
GO
UPDATE dbo.V
    SET
    c1 = 1;

Remarks:
In the above example we try to update the view dbo.V. Because this view contains the constant expression 1, the error is raised.
