Change Tracking (CT) feature was introduced in SQL Server 2008, and is used to get the rows in user tables that have changed, without the data that was changed. You can get the latest data directly from the tracked table.
To list all tables that have Change Tracking (CT) enabled on a SQL Server database, use the following query:
SELECT s.name as Schema_name, t.name AS Table_name, tr.*
FROM sys.change_tracking_tables tr
INNER JOIN sys.tables t on t.object_id = tr.object_id
INNER JOIN sys.schemas s on s.schema_id = t.schema_id
You will get one row for each table that has Change Tracking enabled in the current database.
