| HIGH_VALUE | VARCHAR2(32767) | NO | The expression for the value bound with the partition. |
| HIGH_VALUE_LENGTH | NUMBER | NO | The length of the expression for the value bound with the partition. |
| PARTITION_POSITION | NUMBER | NO | The position of the partition within the index. |
| STATUS | VARCHAR2(8) | NO | Indicates whether the index partition is usable. |
| TABLESPACE_NAME | VARCHAR2(30) | NO | The name of the tablespace that contains the partition. |
| PCT_FREE | NUMBER | NO | The minimum percentage of available space in a block. At present, this column is not supported and is NULL by default. |
| INI_TRANS | NUMBER | NO | The initial number of transactions. At present, this column is not supported and is NULL by default. |
| MAX_TRANS | NUMBER | NO | The maximum number of transactions. At present, this column is not supported and is NULL by default. |
| INITIAL_EXTENT | NUMBER | NO | The size of the initial extent, in the unit of bytes. At present, this column is not supported and is NULL by default. |
| NEXT_EXTENT | NUMBER | NO | The size of secondary extents, in the unit of bytes. At present, this column is not supported and is NULL by default. |
| MIN_EXTENT | NUMBER | NO | The minimum number of extents allowed in the segment. At present, this column is not supported and is NULL by default. |
| MAX_EXTENT | NUMBER | NO | The maximum number of extents allowed in the segment. At present, this column is not supported and is NULL by default. |
| MAX_SIZE | NUMBER | NO | The maximum number of blocks allowed in the segment. At present, this column is not supported and is NULL by default. |
| PCT_INCREASE | NUMBER | NO | The percentage increase in the extent size. At present, this column is not supported and is NULL by default. |

| COMPRESSION | VARCHAR2(13) | NO | Indicates whether compression is enabled for the partitioned index. Valid values: ENABLEDISABLE |
| BLEVEL | NUMBER | NO | The B*-tree level, that is, the depth of the index from its root block to its leaf blocks. A depth of 0 indicates that the root block and the leaf blocks are the same. At present, this column is not supported and is NULL by default. |
| LEAF_BLOCKS | NUMBER | NO | The number of leaf blocks in the index partition. At present, this column is not supported and is NULL by default. |
| DISTINCT_KEYS | NUMBER | NO | The number of distinct keys in the index partition. At present, this column is not supported and is NULL by default. |
| AVG_LEAF_BLOCKS_PER_KEY | NUMBER | NO | The average number of leaf blocks in which each distinct value in the index appears. The value is rounded to the nearest integer. The value is always 1 for indexes that enforce the UNIQUE and PRIMARY KEY constraints. At present, this column is not supported and is NULL by default. |
| AVG_DATA_BLOCKS_PER_KEY | NUMBER | NO | The average number of data blocks in the table that are pointed to by different values in the index that are rounded to the nearest integer. This statistical data is the average number of data blocks containing rows that have a specified value for the indexed columns. At present, this column is not supported and is NULL by default. |
| CLUSTERING_FACTOR | NUMBER | NO | The number of rows in the table based on the value of the index. At present, this column is not supported and is NULL by default. |
