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.
