Error Message:
Msg 2738, Level 16, State 2, Line 1

Severity level:
16.

Description:
This error message appears when you try to create a table with more than one Timestamp columns.

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. Each table in SQL Server can contain just one Timestamp column.

Versions:

Example(s):
CREATE TABLE t
(
 c1 INT,

ALTER TABLE t
 ADD t2 TIMESTAMP
