Virtual column partitioning 11.2.0.2

Hi

We have some large tables that we are planning to make partitioned (Virtual column partitioning).

I need to know what would be the impact on application code change as basically partitioning should be transperent to the application.

In our case we have accountnumber column which is varchar2 (frequently used in where clause of application sql) and we created virtual column as number column with accountnumber_id which is our partition key. Now we have to modify application SQL to replace accountnumber with accountnumber_id for use of partition pruning and partition-wise joins.

Please suggest.

Thanks!!
