Technically, one or more columns can make up the partitioning expression, if you need a complex partitioning scheme.

I've never seen this in practice, but the example given in the PPI orange book is:

     ... PRIMARY INDEX (store_number, product_code, sales_date)
         PARTITION BY store_number * 1000 + product_code;

Something like this would apply if you had two numeric columns that both had small ranges.

With the more common range_n, you are limited to one partitioning column.
