Incremental loading is nothing but the cdc(change data
capture)
used to capture the data like insert,update and deleted
data on a table.

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
