Three tables:
Table A has people's Names
Table B has Activities people are involved
Link Table links multiple people to multiple activities
Table A is One-to-many to Link Table
Table B is One-to-many to Link Table
I have created a test person that I haven't linked to any activities. This record is
_only_ in Table A, with no link in the Link Table. I am trying to produce some kind of report that will tell me that this record is not in the Link table (and any others that might be similar).
