CDCTrackingHelper class

The CDCTrackingHelper class provides convenience methods for accessing data in a _Cdc-Change-Tracking record and its related change table record(s). It is specific to a given CDC source table. An ETL program can create an instance of CDCTrackingHelper for the source table being processed. The ETL program creates a CDCTrackingHelper object for a _Cdc-Change-Tracking buffer, then iterates through the _Cdc-Change-Tracking records using this buffer. The ETL program can then use the convenience methods in the CDCTrackingHelper object to access the record currently in the buffer.
