Definition

SQL Server Change Tracking is a lightweight SQL Server feature that helps applications and synchronisation processes identify rows that changed after a known version.

Why it matters

  • It can support incremental synchronisation without scanning entire tables every time.
  • It gives sync workflows a database-managed way to identify changed rows.
  • It still requires careful retention, version handling, validation, and monitoring.

Common signals

  • A sync process needs to pick up inserts, updates, or deletes since the last run.
  • A team wants a lighter alternative to full table comparison.
  • The application needs to store and advance a last processed change version.

How SQL Cockpit helps

  • SQL Cockpit gives teams operational context around synchronisation choices, job status, validation, and table workflows.
  • Change tracking decisions can be reviewed alongside migration and table synchronisation work.

FAQ

Is SQL Server Change Tracking the same as CDC?

No. Change Tracking identifies that rows changed, while Change Data Capture records more detailed change history.

Can Change Tracking be used for synchronisation?

Yes. It can help identify changed rows for incremental sync, but teams still need validation, retention handling, and operational monitoring.

How does SQL Cockpit relate to Change Tracking?

SQL Cockpit provides workflow visibility around table synchronisation, jobs, validation, and migration context where change tracking may be part of the implementation.
