REM Virtual column-based partitioning
REM 1.Introduce the concept of a virtual column (e.g. Extract the month out of a date)
REM 2.Create a simple virtual column and select from it (you can also highlight that you can collect stats on such a column)
REM 3.Create a virtual column-based partitioned table (for demonstration purposes this can be something goofy like adding two column values or so)
REM 4.insert some data and show the data placement based on the virtual column definitions

-- now, create a table product returns with a virtual column, and partition by this column


create table product_returns
( order_id number not null
, product_id number not null
, customer_id number not null
, quantity number not null
, unit_price number not null
, total_value as (quantity * unit_price) virtual
)
partition by range(total_value)
( partition dont_even_bother values less than (100)
, partition perhaps_the_accountant_cares values less than (1000)
, partition now_it_becomes_worrying values less than (10000)
, partition oops_somebody_be_fired values less than (100000)
, partition this_means_bankruptcy values less than (maxvalue)
)
