Oracle: Partition table by month

Question

My solution(months in german):

PARTITION BY LIST ((to_char(GEBURTSDATUM, \'Month\'))) 
(  
  PARTITION p1 VALUES(\'JANUAR\'),  
  PARTITION p2 VALUES(\'Februar\'         


        

Answer 1

If the table has a date column, the statement below can be used as an example for monthly partitioning starting from today (Oracle 11g):

PARTITION BY RANGE (date_column)
            INTERVAL (NUMTODSINTERVAL(1,'month') )
             (PARTITION p_first VALUES LESS THAN ('16-MAY-2016'));

Answer 2

In 11g you can use function-based partitioning through defining a virtual column: http://www.oracle-base.com/articles/11g/partitioning-enhancements-11gr1.php#virtual_column_based_partitioning

Otherwise, you must manually define and maintain a separate column for the partitioning month.

I'd suggest using month numbers instead of names in either case.
