Msg 8106, Level 16, State 1, Line 1
Table ‘%1!’ does not have the identity property. Cannot perform SET operation.

Severity level:
16.

Description:
This error message appears when you try to use the SET IDENTITY_INSERT setting for a table that does not contain a column, for which the IDENTITY property was declared.

Consequences:

Resolution:
Error of the Severity level 16 are generated by the user and can be fixed by the SQL Server user. The SET IDENTITY_INSERT setting cannot be used on such a table.

Versions:
All versions of SQL Server.

Example(s):
USE tempDB
GO

CREATE TABLE t
(
 i1 INT
)
GO
SET IDENTITY_INSERT t ON
INSERT INTO t SELECT -1
SET IDENTITY_INSERT t OFF
DROP TABLE t
GO

In the above example we try to turn on the IDENTITY_INSERT setting für the table t to insert an explicite value into a column for which the IDENTITY property was declared. Because there no such column in table t, the error is raised.
