Rick,
If you partition on the date field then you set the partition limit with a date type limit.

PARTITION aadedup01 VALUES LESS THAN ('02-01-2003') TABLESPACE aadedup01_data,
PARTITION aadedup02 VALUES LESS THAN ('03-01-2003') TABLESPACE aadedup02_data,
PARTITION aadedup03 VALUES LESS THAN ('041-01-2003') TABLESPACE aadedup03_data,
.....
PARTITION aadedupMAX VALUES LESS THAN (MAXVALUE) TABLESPACE aadedup_dataMAX)
That way you can have monthly partitions each year and then archive the data.

create table aadedupekeys
(

file_id number,
rundate date,

   pk      number(10),
   dk      varchar2(128),

constraint aadedupekeys_pk primary key (file_id,rundate) )
;

Is there anyway to partition a table (above) in months e.g. ('January','Februray'...). I want to use the rundate and list partition it
using the months of the year. How can I do that without actually having to
create another column in the table that only contains the month it belongs
to? I cannot seem to use a function on the rundate field as part of the
partition syntax to generate a month to partition the data.

Thanks for your help,

Rick Stephenson
