We could instead handle that with a generic "this doesn't fit in any other partition" capability. Presumably that would be easy if we're building this on top of inheritance features. If we exclude the issue of needing one or two oddball partitions for +/- infinity, I expect that fixed sized partitions would actually cover 80-90% of cases. -- Jim Nasby, Data Architect, Blue Treble Consulting Data in Trouble?
