I have a customer that would like a report to list all donors that have not contributed for a specific date range. The donors are stored in a table called "Donors" and the contributions in a table called "Contributions". The "Donors" table has a unique identifier of cId. The "Contributions" table contains a cDonors_id foreign key. I have been able to create a SQL statement that returns all of the donors that have contributed for a specific date range. How can I do the opposite and return only the donors with no contributions for a specific date range?

Thanks In Advance!!
