Hi all,
I have a lot of tables that were partitioned by the last DBA by year but the last 10+ years no new partitions were created.
so basically I have tables that have partition names like P1, P2, P3, P4 and PMAX that correspond to years 1/1/2002, 2003, 2004, 2005 and MAXVALUE.

I have used the following code to add new partitions:
ALTER TABLE "<Schema>"."<Tablename>" SPLIT PARTITION "PMAX" AT (TO_DATE('01/01/2006','MM/DD/YYYY')) INTO (PARTITION "P5", PARTITION "PMAX") UPDATE INDEXES PARALLEL;
ALTER TABLE "<Schema>"."<Tablename>" SPLIT PARTITION "PMAX" AT (TO_DATE('01/01/2007','MM/DD/YYYY')) INTO (PARTITION "P6", PARTITION "PMAX") UPDATE INDEXES PARALLEL;
I was wondering if it's possible to start at the other end......by creating a partition for 2017 data before 2006 - 2016 and if so, how to change the code?
