ALTER TABLE hash_example EXCHANGE PARTITION part02 WITH TABLE hash_part02; 这时,分区表hash_example中的part02分区的资料将被转移到hash_part02这个非分区表中。 七、索引 在分区表上可以建立三种类型的索引:1、和普通表一样的全局索引。2、全局分区索引。3、本地分区索引。 它们之间的区别如下图示。 以表ra...

For local indexes, index partitioning is maintained automatically when partitions are affected by maintenance activity. This ensures that the index remains equipartitioned with the underlying table. Oracle's partitioning methods are introduced in the following sections: ...
You performed an export of a table partition with DataPump export (EXPDP) For Example: >expdp directory=data_pump_dir dumpfile=test.dmp logfile=test.log tables=test.table_a:table_partition_2 Then during the import of the table_partition_2, you encounter an ORA-39151 error. ...
each partition of a local index is associated with exactly one partition of the table. This enables Oracle to automatically keep the index partitions in sync with the table partitions, and makes each table-index pair independent. Any actions that make one partition's data invalid or unavailable ...
