What is Rowversion in SQL Server?

Rowversion is a SQL Server binary value that changes when a row is modified. Learn how teams use it in sync, validation, and concurrency workflows.

Definition

Rowversion, formerly known as timestamp, is a SQL Server data type that stores an automatically generated binary value whenever a row containing that column changes.

Why it matters

It gives applications a reliable way to notice that a row was updated.
It can support incremental processing and concurrency checks when used carefully.
It is not a date or time value.

Common signals

An application checks whether a row changed before saving edits.
A sync workflow uses a binary marker to find rows updated since the last run.
Developers confuse rowversion with a timestamp containing the actual update time.

How SQL Cockpit helps

SQL Cockpit helps teams discuss rowversion-based sync designs in the context of table synchronisation and validation.
Operational visibility helps teams understand which jobs and workflows depend on incremental markers.

FAQ

Is rowversion a timestamp?

No. Rowversion is not a date or time. It is a database-generated binary value that changes when a row is inserted or updated.

Can rowversion be used for synchronisation?

Yes, rowversion can help identify changed rows, but teams still need careful checkpoint handling, validation, and failure recovery.

How does SQL Cockpit relate to rowversion?

SQL Cockpit connects rowversion-based synchronisation discussions to table workflows, validation, jobs, and operational context.
