I'm currently working on a system using partition views. It makes life painful for updates and inserts. In this case, it was done because of the time taken to delete data on a quarterly basis.
I believe it would have been better to delete one day's data each night as part of batch processing which would easily have been fast enough. The only problem I can see is that indexes may need to be rebuilt every so often. Received on Sat Apr 25 1998 - 11:13:29 CDT
