Determine partition range start and stop for a partition

Question

Hi,
Using oracle 11.2.0.3
We are using range interval partitioning and partition sget generated automatically. (range-hash) intervbal 1 month
Whilst can check table manually and see start and end range of partition is it possible to query data dictionary to see
the satrt and stop range as wish to have script to automatically rename the system generated partitions based on the range involved e.g if generated partition has max date value
3062013 waoul want PART_201306
Thanks

Answer 1

Thanks for replies.
Have triied following sql but despite partition keyword in from clause is not using partition pruning.
Table belwo retailer_transaction date-range partitioned 1 per month.
If have to explictly use partitiong_date as condition in where clause to get partition pruning.
Need to ab able to determine what start and stop dates for that month is automatically.
Checked user_tab_partitions as have sql geneerator can get partition names but doesn't show partition start an dstop ranges.
How can I achieve this
sql gneerator starts
