Note:
Columns marked with an asterisk (*
) are populated only if you collect statistics on the table with the DBMS_STATS
package.
Note:
The following is true for the columns below that include double asterisks (**) in the column description:
The column can display information about segment-level attributes (for simple partitioned tables) or metadata (for composite partitioned tables). In a simple partitioned table, the partition physically contains the data (the segment) in the database. In a composite partitioned table, the partition is metadata and the data itself is stored in the subpartitions.
