Oracle Partition Table : Data is not inserted in the right Partition

Question

Halo database guru, greeting from Indonesia

i am currently working to migrate one my company big table from non-partition to partition table. each time i tried to insert the data using insert into journal1 select * from journal, the data inserted into journal1 is not partitioned. any clues ?

here is the non-partition table as the source of the data.

CREATE TABLE PRODBMDB.JOURNAL

here is the script i used to migrate the data

insert into journal1
select * from journal

when i check the data in table journal1, the data inserted successfully but did not partition. anyone have clues why is this happen?

Answer 1

DBA_TABLES.NUM_ROWS is the number of rows counted when optimizer statistics were gathered. It does not necessarily represent the real number of rows. Regardless of what is inserted in the table, until statistics are gathered the query will look like this:

select partition_name, num_rows
from dba_tab_partitions
where table_name = 'JOURNAL1';

PARTITION_NAME  NUM_ROWS
--------------  --------
PART1   
PART2   
PART3   
PART4   
PART5   

Gathering statistics will set the number of rows but the number will not stay up-to-date:

begin
    dbms_stats.gather_table_stats('PRODBMDB', 'JOURNAL1');
end;
/

select partition_name, num_rows
from dba_tab_partitions
where table_name = 'JOURNAL1';

PARTITION_NAME  NUM_ROWS
--------------  --------
PART1                  0
PART2                  0
PART3                  0
PART4                  0
PART5                  0
