You want to check out the lookup transformation. See an example here : http://blogs.conchango.com/jamiethomson/archive/2006/09/12/SSIS_3A00_-Checking-if-a-row-exists-and-if-it-does_2C00_-has-it-changed.aspx

Hi,

You could also use the Slowly Changing Dimension task for this purpose.

Cheers

Both the lookup and slowly changing dimensions are good approaches. A third approach would be to use your destination as a data source, and then outer join the tables together. Then, you split the resultset on the basis of the nulls which indicate the presence or absence, and work on those streams as INSERT or UPDATEs.
