Should have been clearer in my previous post, you can get rid of the nulls
by filtering out the entire row.

Adrian,

Thank you. I'm rebuilding the statement from the inside out (which helps me
learn more SQL in the process). For example,

select * from activities where next_contact is not null and
         next_contact <= 'today' and next_contact > '2018-12-31';

works as written. This suggests that it's the placement within the two joins
that needs correcting. Now I'll add the two joined tables one at a time and
learn how to structure the whole statement.

Best regards,

Rich
