Msg 2738, Level 16, State 2, Line 1
A table can only have one timestamp column. Because table ‘%.*ls’ already has one, the column ‘%.*ls’ cannot be added.
This error message appears when you try to create a table with more than one Timestamp columns.
The T-SQL statement can be parsed, but causes the error at runtime.
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.
All versions of SQL Server.
CREATE TABLE t
ALTER TABLE t
ADD t2 TIMESTAMP
In the above example, we try to add a second timestamp column to the table t. Because table t already contains such a timestamp column, the error is raised.
