I am trying to get a list of the next appointment for a group of people. I can easily get a list of all future appointments for these people. To narrow it down to 1 row per person I used the GROUP BY clause. However, which record does the data come from when using GROUP BY. In other words: A person may have 10 appointments, but I have a single record for each person with a date. I don't know how it decides which of the 10 dates to display. Is it the first record, last record, random record?

TIA,
Marcus.
