Error Message:
Msg 4449, Level 16, State 1, Line 2
Using defaults is not allowed in views that contain a set operator.
Severity level:
16.
Description:
This error message appears when you try to insert into a view that contains a set operator, but specify the DEFAULT keyword as part of the INSERT or UPDATE statement
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 use the DEFAULT keyword when inserting or updating data through a view that contains a set operator.
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.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 int
)
GO
CREATE VIEW dbo.V
AS
SELECT
c1, c2
FROM
dbo.T
UNION ALL
SELECT
c1, c2
FROM
dbo.T1
GO
INSERT INTO dbo.V (c1, c2) VALUES (DEFAULT, 1);
Remarks:
In the above example we try to insert into the view dbo.V. Because dbo.V contains a set operator, the INSERT statement using the DEFAULT keyword raises the error.
