Oracle Database 11g Enterprise Edition Release

Trying to write a script to determine if a partition is setup for interval or range partitioning, but it looks like the INTERVAL column was not added to ALL_TAB_PARTITIONS view until 11.2.
Is this the case? And if so, is there a way to identify if a partition is interval or not w/o upgrading


INTERVAL VARCHAR2(3) Indicates whether the partition is in the interval section of an interval partitioned table (YES) or whether the partition is in the range section (NO)
