Column Containing Partition Key Condition Information

Question

I am using 11.2.0.2 on AIX 6.1.
I am creating a range partition table as below.
CREATE TABLE SALES_RANGE
  ( prod_id       NUMBER(6)
  , cust_id       NUMBER
  , time_id       DATE
  , channel_id    NUMBER(3)
PARTITION BY RANGE (time_id)
( PARTITION sales_q1_2012 VALUES LESS THAN (TO_DATE('01-APR-2012','dd-MON-yyyy'))
, PARTITION sales_q2_2012 VALUES LESS THAN (TO_DATE('01-JUL-2012','dd-MON-yyyy'))
, PARTITION sales_q3_2012 VALUES LESS THAN (TO_DATE('01-OCT-2012','dd-MON-yyyy'))
, PARTITION sales_q4_2012 VALUES LESS THAN (TO_DATE('01-JAN-2013','dd-MON-yyyy'))
);I can find all the information related to this table in dictionary tables like below.
SQL> SELECT OWNER,
       TABLE_NAME,
       PARTITIONING_TYPE,
       SUBPARTITIONING_TYPE,
       PARTITION_COUNT,
       PARTITIONING_KEY_COUNT,
       STATUS,
       DEF_TABLESPACE_NAME
FROM DBA_PART_TABLES
WHERE OWNER='SCOTT';
OWNER                          TABLE_NAME                     PARTITION SUBPARTIT PARTITION_COUNT PARTITIONING_KEY_COUNT STATUS   DEF_TABLESPACE_NAME
SCOTT                          SALES_RANGE                    RANGE     NONE                    4                      1 VALID    USERS
SQL> SELECT TABLE_OWNER,
       TABLE_NAME,
       COMPOSITE,
       PARTITION_NAME,
       PARTITION_POSITION,
       TABLESPACE_NAME,
       LAST_ANALYZED
FROM DBA_TAB_PARTITIONS
WHERE TABLE_OWNER='SCOTT'
ORDER BY PARTITION_POSITION;
TABLE_OWNER                    TABLE_NAME                     COM PARTITION_NAME                 PARTITION_POSITION TABLESPACE_NAME                LAST_ANAL
SCOTT                          SALES_RANGE                    NO  SALES_Q1_2012                                   1 USERS                          17-FEB-12

SCOTT                          SALES_RANGE                    NO  SALES_Q3_2012                                   3 USERS                          17-FEB-12
SCOTT                          SALES_RANGE                    NO  SALES_Q4_2012                                   4 USERS                          17-FEB-12
SQL> SELECT * FROM DBA_PART_KEY_COLUMNS WHERE OWNER='SCOTT';
OWNER      NAME            OBJEC COLUMN_NAME     COLUMN_POSITION
SCOTT      SALES_RANGE     TABLE TIME_ID                       1But where can i find the partition key condition i.e. *"VALUES LESS THAN (TO_DATE('01-APR-2012','dd-MON-yyyy'))"* in any dictionary table ?

Answer 1

Thanks for your quick reply....
I have already checked and included in my example given.
SQL> SELECT * FROM DBA_PART_KEY_COLUMNS WHERE OWNER='SCOTT';
OWNER      NAME            OBJEC COLUMN_NAME     COLUMN_POSITION
SCOTT      SALES_RANGE     TABLE TIME_ID                       1It's only giving the column name on which partitioning is done, not the partitioning condition.
My question was, in which table i can check the criteria on which i have range partitioned a table ? Is there an dictionary table which holds information like:
PARTITION_NAME     PARTITION_CONDITION
SALES_Q1_2012       VALUES LESS THAN (TO_DATE('01-APR-2012','dd-MON-yyyy')I hope i am clear in my question......
