timestamp is a synonym for rowversion data type and depends on the behavior of data type synonyms. For DDL operations, use rowversion instead of timestamp where possible. For more information, see Data Type Synonyms (Transact-SQL) .
The timestamp syntax is deprecated. This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new developments and plan to change applications that currently use this feature.
