Wim,

As the error - in Dutch - says: The used database driver (RDS driver) does not support SQL() statements.

This makes sense as there is no real database to run queries on.

What you should do instead is:
- Collect data for RDS
- Run report
- Ask a confirmation question whether the report was succesful and the program should update the database
- Run the SQL statement (or better instructions via the DDs) to update the database
