I'm having some problem in fact table partitioning. My fact table is designed as follows,

timeid  - char
productid - char
customerid - char
geographyid - char

& Measures..

The best option to partition my table on geographyID by range partition. Since the column is character I can not use to_number while partitioning the table. If I use LESS THAN option for a character column the 900 comes after 1200. Actually the record containg geographyID 1200 should come in another partion because it is in another geography.

Please give me some suggestions to overcome this problem. The fact table is very huge and contains 1.5 million record a month.

Best Regards,

why are you using char for the IDs?
I recommand you to always use number.
So my solution would be to create a new table with IDs usgin numbers and populate it with the data of your existing table.
