Help with TSQL Aggregate query using TOP

Posted on 2003-11-28

I have two tables, Person (id int, name varchar()) and Appointment(date datetime, personid int, notes varchar())
personid from the Appointment table reference is from the Person table.

The Person table contains is and name of some people. The Appoinment table contains the date the each person was visited. There can be many entries in the Appoinment table for each person. i.e. They is a record of many visits for each person.

I need a query that gives the 5 most recent visits for ALL the people in the Person table, not just one person. So I need a query that for each person in the person table will return the 5 (or however many) most recent vists. i.e.(date <= today).

for convenience add an Identity field to Appoint ment table (AppointmentID) then
 Person P

Appointment A
P.PersonID = A.PersonID
A.Appointmentid in(Select TOP 5 AppointmentID from Appointment AP Where AP.PersonID = A.PersonID and AP.Date<=getdate() order by AP.Date DESC)
