CHAPTER 13 ■ PARTITIONING
PART_1
PART_2
Figure 13-3. List partition insert example
If you want to segregate these seven states into their separate partitions, as we have,
but have all remaining state codes (or, in fact, any other row that happens to be inserted
that doesn’t have one of these seven codes) go into a third partition, then we can use the
VALUES ( DEFAULT ) clause. Here, we’ll alter the table to add this partition (we could use
this in the CREATE TABLE statement as well):
ops$tkyte@ORA10G> alter table list_example
2 add partition
3 part_3 values ( DEFAULT );
Table altered.
ops$tkyte@ORA10G> insert into list_example values ( 'VA', 'data' );
1 row created.
All values that are not explicitly in our list of values will go here. A word of caution on the
use of DEFAULT: once a list partitioned table has a DEFAULT partition, you cannot add any more
partitions to it:
ops$tkyte@ORA10G> alter table list_example
2 add partition
3 part_4 values( 'CA', 'NM' );
alter table list_example
