Re: On TRUNCATE table does the indexes also get truncated.

Not having data in the indexes as some have noted, is not answer the question of whether or not the index was truncated.

Here's a simple test that will answer the question.

Feel free to use this methodology in the future. :)

Jared

drop table t;

create table t
tablespace users
as
select *
from dba_objects
/

create index t_idx on t (owner, object_name, created, last_ddl_time, timestamp, status )
tablespace users
/

col segment_name format a30
col blocks format 999,999
col bytes format 999,999,999

select segment_name, sum(blocks) blocks, sum(bytes) bytes from user_extents
where segment_name in ('T','T_IDX')
group by segment_name
/

truncate table t;

select segment_name, sum(blocks) blocks, sum(bytes) bytes from user_extents
where segment_name in ('T','T_IDX')
group by segment_name
/
