Rick:

Check out the DBMS_UTILITY.GET_HASH_VALUE() function. This function will tell you what partition the data is stored in.

Partition pruning can still be used.

Using range partition you know exactly where the records are stored. I do not understand how one knows
where the row is stored using hash partitioning. Can the optimizer still use partitioning pruning with hash
partitions? Can someone explain how hash partitions work? My sources are confusing.
