Odd queries to find sequential events
I work with a university organization, and we use Access 2000 to track student attendance at our events.
Given the following three tables (with the obvious field definitions & relationships):
tblStudents: StudentID, StudentName
tblEvents: EventID, EventName, EventDate
tblEventAttendance: EventID, StudentID
How can I answer the following questions?
* For any given event, how many students came for
the Nth time? (i.e, how many first timers, second timers)
* For any given event, what % of the students who came
for the first time to the previous event returned for
a second event? What % of those who came twice actually
came back for a third event? For any given number of
visits, what % of students make it at least one more time?
* Generate a list of students who have been to three or
more events yet have missed a given consecutive number
of events. (i.e., who has missed our last two events?)
These seem like straightforward questions, but I can't find an easy answer to them. Ideas?

Re: Odd queries to find sequential events
You might check into crosstab queries. This gives a different way of looking at and sorting your data.
