I'm using the 11g interval partitioning feature in one of my tables. I set it up to create 1 day partitions on a timestamp field and created a job to delete data 3 months old. When I try to delete the oldest partition I get the following error:
ORA-14758: Last partition in the range section cannot be dropped
I would have thought that "Last" refers to the newest partition and not the oldest. How should I interpret this error? Is there something wrong with my partitions or should I in fact keep the oldest partition there at all time?
