Primary Key Causing Problem in Interval Partition Exchange

Question

DB : 11.2.0.2
OS : AIX 6.1
I am getting the problem while exchanging data with interval partitioned table. I have a interval partitioned table and a normal staging table having data to be uploaded.
Following are the steps i am doing.
SQL> CREATE TABLE DEMO_INTERVAL_DATA_LOAD (
                ROLL_NUM        NUMBER(10),
                CLASS_ID        NUMBER(2),
                ADMISSION_DATE  DATE,
                TOTAL_FEE       NUMBER(4),
                COURSE_ID       NUMBER(4))
                PARTITION BY RANGE (ADMISSION_DATE)
                INTERVAL (NUMTOYMINTERVAL(3,'MONTH'))
                ( PARTITION QUAT_1_2012 VALUES LESS THAN (TO_DATE('01-APR-2012','DD-MON-YYYY')),
                 PARTITION QUAT_2_2012 VALUES LESS THAN (TO_DATE('01-JUL-2012','DD-MON-YYYY')),
                 PARTITION QUAT_3_2012 VALUES LESS THAN (TO_DATE('01-OCT-2012','DD-MON-YYYY')),
                 PARTITION QUAT_4_2012 VALUES LESS THAN (TO_DATE('01-JAN-2013','DD-MON-YYYY')));
Table created.
SQL> ALTER TABLE DEMO_INTERVAL_DATA_LOAD ADD CONSTRAINT IDX_DEMO_ROLL PRIMARY KEY (ROLL_NUM);
Table altered.

SYS_P98 partition is added to table automatically.

Commit complete.
Since, i need a partition in DEMO_INTERVAL_DATA_LOAD table, which can be used in partition exchange, so i create a new partition as below:
SQL> LOCK TABLE DEMO_INTERVAL_DATA_LOAD PARTITION FOR (TO_DATE('01-APR-2013','DD-MON-YYYY')) IN SHARE MODE;
Table(s) Locked.

FROM DBA_TAB_PARTITIONS
    WHERE TABLE_OWNER='SCOTT'
   AND TABLE_NAME='DEMO_INTERVAL_DATA_LOAD'
   ORDER BY PARTITION_POSITION;

no rows selectedPlease suggest.

Answer 1

First, thanks for posting the code that lets us reproduce your test. That is essential for issues like this.
Because the primary key is global you will not be able to use
INCLUDING INDEXES
WITH VALIDATION;And you will need to add the primary key to the temp table
ALTER TABLE DEMO_INTERVAL_DATA_LOAD_Y ADD CONSTRAINT IDX_DEMO_ROLL_Y PRIMARY KEY (ROLL_NUM);The the exchange will work. You will need to rebuild the primary key after the exchange.
