This explains the meaning of my "generic" question fairly well. The solution is only good for one table at one particular moment, because if you want to change the table you have to find out all the new partition names, and edit every line of code. Even if you want to check the same table, you may have dropped and added some partitions since last time.
Of course, Matthew supplied a solution using pl/sql that implemented this specific method with a generic mechanism.
