Partiton by range date field

Question

I am creating a script that will automatically create the partitions. My partition key is a Date field
I am testing changing date field uing Date, Timestamp and Timestamp with local time zone.
How should my values less than clause look for Timestamp and
Timestamp with local time zone?
For example, testing for date looks like this:
Partition 2005_JAN values less than (to_date('2005-02-01 00:00:00',SYYYY-MM-DD HH24:MI:SS') tablespace data01;

Answer 1

Mike,
if I understand your task right, you would like to have a script which would automatically create new partition for every new month/year.
You can use something like that using EXECUTE IMMEDIATE and dynamic
SQL to create new partition:
SQL> create table t (date# date)
  2  partition by range(date#)
  3  (PARTITION DATES_AUG VALUES LESS THAN (TO_DATE('01-09-2005','DD-MM-YYYY')));
Table created.
SQL> select table_name, partition_name from user_tab_partitions
  2  where table_name = 'T';
TABLE_NAME                     PARTITION_NAME
T                              DATES_AUG
SQL> declare
  2   cnt number(1);
  3  begin
  4 
  5   select count(1) into cnt from user_tab_partitions
  6   where table_name = 'T' and partition_name = 'DATES_' ||
  7   to_char(last_day(sysdate)+1,'MON');
  8 
  9   if cnt = 1 then return; end if;
10 
11   execute immediate 'ALTER TABLE t ADD PARTITION DATES_'
12   || to_char(last_day(sysdate)+1,'MON') ||
13   ' VALUES LESS THAN (TO_DATE(''' || to_char(last_day(sysdate)+1,'DD-MM-YYYY') || ''''
14   || ',' || '''DD-MM-YYYY''))';
15  end;
16  /
PL/SQL procedure successfully completed.
SQL> select table_name, partition_name from user_tab_partitions
  2  where table_name = 'T';
TABLE_NAME                     PARTITION_NAME
T                              DATES_AUG
T                              DATES_OCTTo be franky this is hardly relevant forum to ask this sort or questions, it would be better to ask it in SQL-PL/SQL or Database General ones.
Rgds.
