Hello All

I need to create a partitioned table base on the last three digits on 9 digits number.

Create table test (zip_and_city_code number(9));

The zip code is 6 digits and the city code is 3 digits.

The design is from an application that used btrieve and is now ported to Oracle.
(I would not allow this design if it was a new system).

I want to group every city records into its own partition.

First I tried to use range partitioning based on a function on the field and it does not work.

Then I thought about using hash partitioning using my own hash function but could not find
where I can use my own hash function.

Any help to implement this @#$% design will be really appreciated.
