SQL> select partition_name, interval, high_value
from dba_tab_partitions where table_name = 'SALES'
order by partition_position; 2 3
PARTITION_NAME INTERVAL HIGH_VALUE
-------------------- --------- -------------------------------------------------------------------------------------
P0901 NO TO_DATE(' 2009-02-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN')
SYS_P11046 YES TO_DATE(' 2009-07-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN')
SYS_P11047 YES TO_DATE(' 2009-10-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN')
