You may define the 2 different values and pass in the report based on select.
Try to look for possible values using Criteria->Column->Filter->Advanced button->Convert filter to SQL.
Since you are using SQL here I dont think you have limits to do... :)
So using a single variable is enough and this would be the easy way correct me if I'm wrong.
If helps mark Any updates on this?
