Would there be any reason to create a single column index on the PARTITION_KEY column (which is a VARCHAR2 representation of a date --- I know, I know, bear with me !) ?
So, we have 24 PARTITION_KEY values for the 24 months that we are holding data. Why have a single-column index on PARTITION_KEY ?

(no this isn't a trick question : I am really confused by this design that I see having been implemented).
