Incremental reload - Comparing sql database to qvd

Hi all,

For a current project, we would like to have an incremental reload.

We cannot check the date of our latest record and use this as a variable, because records can change overtime in the DB.

What we would like is to use a where exists, but for SQL.

We load all our unique ID's from the historic QVD,

Then we'd like to load everything from our SQL database where there is no match between the ID from the SQL database, and ID from the historic qvd.

Anybody has an idea how to realise this?

Or better suggestions

Best regards

Maxim Polderman
