An explicit value for the identity column in table ‘%1!’ can only be specified

Error Message:
Msg 8101, Level 16, State 1, Line 1
An explicit value for the identity column in table ‘%1!’ can only be specified

Severity level:
16.

Description:
This error message appears when you try to insert a value into a column for which the IDENTITY property was declared, but without having specified a column list in the INSERT statement and without having set the SET IDENTITY_INSERT setting on.

Consequences:
The T-SQL statement can be parsed, but causes the error at runtime.

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 must be turned on and the INSERT statement must contain a column list.

Versions:
All versions of SQL Server.

Example(s):
USE tempDB
GO

CREATE TABLE t
(
 i1 INT IDENTITY
)
GO
INSERT INTO t SELECT -1
DROP TABLE t
GO

Remarks:
In order to run the above batch free of errors, it must be rewritten to:
USE tempDB
GO

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

When you specify a column list in the INSERT statement, but do not set IDENTITY_INSERT to on, SQL Server raises error 544.
