Experts,

i want to find how much unused pace for a partitioned table and indexes. and i need to reclaim that space.

how can i do that.

currently we are dropping old partition. will it release entire space that partition is occupied?

could you please provide me any document for this. i am using dbms_space package for partitioned tables. i am getting some errors.

dbms_space is the way and if you don't post the error we can't help.

The message is clear if type is "TABLE PARTITION" then a partition must be given.
So do it.
If you want for each partition then repeat for each partition.
