Change Data Capture (CDC) feature was introduced in SQL Server 2008, and is used to get the historical change information for a user table.
To list all tables that have Change Data Capture (CDC) enabled on a SQL Server database, use the following query:
SELECT s.name AS Schema_Name, tb.name AS Table_Name
, tb.object_id, tb.type, tb.type_desc, tb.is_tracked_by_cdc
FROM sys.tables tb
INNER JOIN sys.schemas s on s.schema_id = tb.schema_id
WHERE tb.is_tracked_by_cdc = 1
You will get one row for each table that has Change Data Capture enabled in the current database.
