你的意思是local partitioned index?
global partitioned index是可以删除单个分区的。
reference:
You cannot explicitly drop a partition of a local index. Instead, local index partitions
are dropped only when you drop a partition from the underlying table.
If a global index partition is empty, you can explicitly drop it by issuing the ALTER
INDEX ... DROP PARTITION statement. But, if a global index partition contains data,
dropping the partition causes the next highest partition to be marked UNUSABLE. For
example, you would like to drop the index partition P1, and P2 is the next highest
partition. You must issue the following statements:
ALTER INDEX npr DROP PARTITION P1;
ALTER INDEX npr REBUILD PARTITION P2;
这里的分区索引,是基于分区表的全局索引
还是基于非分区表的索引分区?就是素引本身是分区的? |
