Partition exchange loading for specific subpartitions

Question

Hi All,
Looking at an archive strategy - where we have to archive a specific dataset.
Rather than a insert/delete routine - I was thinking of using partition exchange.
The to-be archived table is interval range partitioned on date, with a list subpartition on country.
It is for specific countries that I want to partition exchange.
    create table
    test_table
    (tbl_id number,
    country varchar2(2),
    sales_dt date,
    volume number)
    partition by range (sales_dt) interval (NUMTOYMINTERVAL(1,'Month'))
    subpartition by list (country)
    Subpartition template
    (subpartition p_ireland values ('IR'),
    subpartition p_france values ('FR'),
    subpartition p_other values (DEFAULT))
    (partition before_2008 values less than (to_date('01-JAN-2008','DD-MON-YYYY'))); The data loaded falls into the partitions and subpartitions correctly. All the partitions names are system generated.
When I come to partition exchange for all the 'FR' subpartitions- I can't determine the logic.
Using
    Alter table test_table
    exchange subpartition system_generated_name
    with table TEST_TABLE_ARCH;I can swap out a specific 'known' subpartition.
I know you can use the 'for' logic with Oracle 11g but can't get the syntax to work.
Any ideas?

Answer 1

The error means you are trying to swap a partition that still contains data in a configuration where OWB expects an empty partition. How did you set the "Replace existing data in Target Partition" configuration parameter?
Also, for more details on PEL, review the 10.19 to 10.27 pages of the user manual.
