You can certainly use the RowVersion column for incremental loads, if you have it on the source, and you should not really need anything else. Although, I would recommend using some sort of hashbyte algorithm as well to be thorough. I provided some links below to get you started. Hope they help.

Tip: When using Timestamp/Rowversion, for good measure, I always like to subtract some set number from the max rowversion to ensure I pick up any updates missed due to lag.

Hi,
I want to use rowversion for incremental loads in SSIS. Can I use rowversions alone or do need
some other fields....how can I save the last rowversion value in table and how I query the table for
next loads.

Thanks
Kicki
