Incremental loading is nothing but the cdc(change data
capture)
used to capture the data like insert,update and deleted
data on a table.
1)for this we need exec the sp against the db is to enable
the cdc.(select is_cdc_enabled where db_name='cdc_test')
2)Enable the cdc against the table in the db.(exec
sys.sp_cdc_enable_table @source_schema=-----,@source_name=-)
3)wheather the db/table enabled for the cdc by writing a
select query aginst db/table.If it returns 1 enabled or it
returns 0 not enabled.
(select is_tracked_by_cdc from sys.tables where tab_name='--
--')
