Defaults cannot be created on columns of data type timestamp. Table '%.*ls', column '%.*ls'.

Error Message:
Msg 1755, Level 16, State 0, Line 1
Defaults cannot be created on columns of data type timestamp. Table ‘%.*ls’, column ‘%.*ls’.

Severity level:
16.

Description:
This error message appears when you try to create a DEFAULT constraint for a column of the type timestamp.

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. You must remove the DEFAULT constraint statement.

Versions:
All versions of SQL Server.

Example(s):
CREATE TABLE #t
(
 t1 TIMESTAMP NOT NULL DEFAULT 0
)

Remarks:
TIMESTAMP values are automatically generated and assigned by SQL Server. The specification of a DEFAULT constrain for a column of this data type is unnecessary and therefore not allowed.
