Sample query
Query all index subpartitions (subpartitions) that are accessible to the current user in the databases.
obclient [SYS]> SELECT INDEX_OWNER, INDEX_NAME, PARTITION_NAME, SUBPARTITION_NAME, HIGH_VALUE, PARTITION_POSITION, SUBPARTITION_POSITION FROM ALL_IND_SUBPARTITIONS;
The query result is as follows:
+-------------+----------------+----------------+-------------------+------------+--------------------+-----------------------+
| INDEX_OWNER | INDEX_NAME | PARTITION_NAME | SUBPARTITION_NAME | HIGH_VALUE | PARTITION_POSITION | SUBPARTITION_POSITION |
+-------------+----------------+----------------+-------------------+------------+--------------------+-----------------------+
| SYS | TBL2_F_RL_IDX1 | P0 | SP0 | 1,3 | 1 | 1 |
| SYS | TBL2_F_RL_IDX1 | P0 | SP1 | 4,6 | 1 | 2 |
| SYS | TBL2_F_RL_IDX1 | P0 | SP2 | 7,9 | 1 | 3 |
