My database stores people and the events they have attended. I have a group of 100 people in the database and want to count the number of events each has attended. I have the total list of people in "People list", a list of events in "Events table" and a linking table (which has rows that store all the links between the two: a1,a2,b1,b2,b3,b4,c1...). Currently, to count the number of events each person has attended I am using the count function on the link table. Unfortunately, this does not display any of the people who have not yet attended an event. Is there a way of displaying all the people in "People list", count the number of times they occur in the link table, and displaying "0" for those that have not attended anything?
