Re: Group-wise Maximum performance
Yep you are quite right, but I'm afraid I haven't explained the problem well enough.
The database contains updates for objects. Each object has a name and an update time. Basically I need the latest update for each object. The 'latest' for each object may be a different time for each, for example the latest update for object A may be 10:00 AM, but the latest update for object B may be 11:00 AM.
Cheers,
Jon.
