Question

dropping partition with a clause

Asked by: nh

Hi there!
I have a partitionned table by date:

> create table T (d date, i integer) partition by range(d) (partition pi
values less than (to_date('01012003','ddmmyyyy')));

Each partition is huge (about 100.000 lines) and concerns a particular day.

Then I store data for 370 days.

So each day I add a partition and drop a 370 days old one...

I wish to know if there is a way to drop several partitions with query like:
>alter table T drop partition pi where d < aDate;

Indeed if I drop only the 370 days old partition (and not 370 and more years old partition), if one day I do not execute this query the partition will still exist...

e.g:

T:
d i
01012001 20 partition p01012001
02012001 29 partition p02012001
03012001 30 partition p03012001

I wish to delete both p01012001 and p02012001...

In real case I do not know which partition exists before date d...

Many thanks...
