Is there any way using the sort command to get something like a GROUP BY clause?
I'm trying to sort through race_event records and group them by those individuals that raced together in the same race on the same date at the same track, but i run into a problem when there were days when the track had qualifying races, plus regular races on the same day; so there could be two Race 1's, Race 2's, etc for the same date at the same track.
I tried a sort like:
where
k3 is a date
k4 is the racetrack
k9 is the class of race (would show it was a qualifier or a regular race)
k29 is the race number
k8 is the purse of race (would show 0 for qualifier and dollar amount for regular race)
k28 is the names of the top three finishers
but this does not sort right: it does not group them together into their respective races correctly. Any suggestions?
