sys.sp_cdc_scan is called internally by sys.sp_MScdc_capture_job if the SQL Server Agent capture job is being used by change data capture. The procedure cannot be executed explicitly when a change data capture log scan operation is already active or when the database is enabled for transactional replication. This stored procedure should be used by administrators who want to customize the behavior of the capture job that is automatically configured.
Requires membership in the db_owner fixed database role.
