Hi....

Why not you can try with partition related dictionary views:

Here is my query:

SCOTT_at_ORANS9I.US.ORACLE.COM> select table_name, partition_name, high_value, partition_position  from dba_tab_partitions a where partition_position = (select max(partition_position)
  2  from user_tab_partitions b where a.table_name=b.table_name)
  3  ;

TABLE_NAME                     PARTITION_NAME
------------------------------ ------------------------------
HIGH_VALUE
PARTITION_POSITION
EMP_PART1                      P4

maxvalue
2
EMP_PART2                      P2

9000
3

SCOTT_at_ORANS9I.US.ORACLE.COM> ALTER TABLE EMP_PART2 ADD PARTITION P4 VALUES LESS THAN(10000);
Table altered.

SCOTT_at_ORANS9I.US.ORACLE.COM> select table_name, partition_name, high_value, partition_position  from dba_tab_partitions a where partition_position = (select max(partition_position)
  2  from user_tab_partitions b where a.table_name=b.table_name)
  3  ;

TABLE_NAME                     PARTITION_NAME
------------------------------ ------------------------------
HIGH_VALUE
PARTITION_POSITION
EMP_PART1                      P4

maxvalue
2
EMP_PART2                      P4

10000
4

SCOTT_at_ORANS9I.US.ORACLE.COM> RGDS,

Hi Connor

Thanq for responding.

In dba_tab_partitions there is no such column like partition_id, and I would like to generate a list at schema level for each table.

That means, this script should capture the latest (last) partitions for each table (if it is partitioned) for a given schema.

Is there a way?

I tried with the following query. But there is some bug in that. It is not capturing the last partition (in a whole database):

select object_name,owner ,subobject_name from dba_objects where data_object_id in (select data_object_id from dba_objects where created in(select max(created) from dba_objects ) and data_object_id is not null);

Can anybody debug this.?

Thnx and Regards,

Srinivas

declare
  pname varchar2(100);

begin
  select partition_name
  into pname
  from user_tab_partitions
  where table_name = ...
  and partition_id =

    ( select max(partition_id) 
      from user_tab_partitions
      where table_name = ... );

  execute immediate 'analyze table ... partition
('||pname||')';
end;

or something similar to that..
