ORA-14314: resulting List partition(s) must contain atleast 1 value

Question

Hi,
Using: Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit Production, Windows 7 Platform.
I'm trying to understand Exchange Partition and Split (List) partitioning. Below is the code I'm trying to work on:
  CREATE TABLE big_table (
  id            NUMBER(10),
  created_date  DATE,
  lookup_id     NUMBER(10),
  data          VARCHAR2(50)
declare
  l_lookup_id big_table.lookup_id%type;
  l_create_date date;
begin
  for i in 1 .. 1000000 loop
    if mod(i,3) = 0 then
       l_create_date := to_date('19-mar-2011','dd-mon-yyyy');
       l_lookup_id := 2;
    elsif mod(i,2) = 0 then
       l_create_date := to_date('19-mar-2012','dd-mon-yyyy');
       l_lookup_id := 1;
    else
       l_create_date := to_date('19-mar-2013','dd-mon-yyyy');
       l_lookup_id := 3;
    end if;
    insert into big_table(id, created_date, lookup_id, data)
       values (i, l_create_date, l_lookup_id, 'This is some data for '||i);
  end loop;
  commit;
end;
alter table big_table add (
constraint big_table_pk primary key (id));
exec dbms_stats.gather_table_stats(user, 'BIG_TABLE', cascade => true);
create table big_table2 (
id number(10),
created_date date,
lookup_id number(10),
data varchar2(50)
partition by list (created_date)
(partition p20991231 values (TO_DATE(' 2099-12-31 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN')));
alter table big_table2 add (
constraint big_table_pk2 primary key(id));
alter table big_table2 exchange partition p20991231
with table big_table
without validation
update global indexes;
drop table big_table;
rename big_table2 to big_table;
alter table big_table rename constraint big_table_pk2 to big_table_pk;
alter index big_table_pk2 rename to big_table_pk;
exec dbms_stats.gather_table_stats(USER, 'BIG_TABLE', cascade => TRUE);
I'm trying to split the data by moving created_date=19-mar-2013 to new partition p20130319. I tried to run the below query but failed with error. Where am I doing it wrong?
Thanks.
alter table big_table
split partition p20991231 values (to_date('19-mar-2013','dd-mon-yyyy'))
into (partition p20130319
     ,partition p20991231
Error report:
SQL Error: ORA-14314: resulting List partition(s) must contain atleast 1 value
14314. 00000 -  "resulting List partition(s) must contain atleast 1 value"
*Cause:    After a SPLIT/DROP VALUE of a list partition, each resulting
           partition(as applicable) must contain at least 1 value
*Action:   Ensure that each of the resulting partitions contains atleast
           1 value

Answer 1

I stand corrected.
Below are the steps I have gone through to understand:
1. How to partition a table with data in it.
2. Exchange partition.
3. Split partition (List).
4. Split data to more than 2 partitions.
Please correct me if I'm missing anything.

      l_create_date := to_date('19-mar-2011','dd-mon-yyyy');
