Interval partitioned tables can be used as parent tables for reference partitioning. Use Oracle alter table and alter index commands to move tables and indexes into these new tablespaces. These input data columns have names specifying a category value, such as Q1, Q2, Q3, Q4. At any time in the second terminal window, you can re-excute the tail t3list.
