Question

I would like generate a list of partition without having to manually type them and I can also choose how many partition I want to create.
I’m using partition by range.
Please see below example.

P_PARTITION_20120830 VALUES LESS THAN ('2012-08-30')
P_PARTITION_20120930 VALUES LESS THAN ('2012-09-30')
P_PARTITION_20121030 VALUES LESS THAN ('2012-10-30')
...
and so on

This is what I have come up so far.

select  'P_PARTITION_' || to_char(add_months(sysdate, 1),'YYYYMMDD')
|| ' VALUES LESS THAN ' || to_char(sysdate, '(''YYYY-MM-DD'')') 
from dual;

Any feedback would be appreciated.
Thank you.

Answer 1

This will generate partitions names for twelve months. Adjust the bounds in the CONNECT BY clause to produce the number you need.

select  'P_PARTITION_' || to_char(add_months(sysdate, level),'YYYYMMDD') 
|| ' VALUES LESS THAN ' || to_char(sysdate, 'YYYY-MM-DD')  
from dual
connect by level <= 12;
