Note
- In OceanBase Database V4.2.0 and later, this view is no longer in use because the concept of partition is deprecated in table groups. You can still query this view, but the return result is empty.
- In OceanBase Database V4.2.0 and later, you can query the DBA_OB_TABLEGROUPS view for table groups. For more information about table groups, see Overview.
