Hi,
I have a small table like that
create table TRANSACTION_DETAIL
(
  transaction_detail_seq NUMBER(10) not null,
  user_name              VARCHAR2(50),
  host_name              VARCHAR2(50),
  host_address           VARCHAR2(50),
  description            VARCHAR2(200) not null,
  transaction_id         NUMBER(10) not null,
  inserted_date          DATE default sysdate not null
)
tablespace USERS

In that table I have only 12630 rows but it consume 1342177280 bytes (1.3 Gig) in USERS tablespace.
Please help.

alter table ... enable row movement;
alter table ... shrink space;

Welcome to the forum. Please read our OraFAQ Forum Guide, if you have nt done so already.

You may need to use the ALTER TABLE...SHRINK SPACE command, http://docs.oracle.com/cd/E16655_01/server.121/e17636/schema.htm#ADMIN10161

Welcome to this Forum & THANKS for reading the Posting Guidelines.

I suspect that at some point in the past, TRANSACTION_DETAIL table contained many more rows which were subsequently deleted.
Is above correct.
Will this table collect many more rows in the future?

>In that table I have only 12630 rows but it consume 1342177280 bytes (1.3 Gig) in USERS tablespace.
why do you consider above to require any action on your part?
Do you suffer from Compulsive Tuning Disorder?

Hi guys,
Finally I found the problem: I exported data from a huge system with compress extent = Y and import it into test bed. After that I delete all rows from the tables. But consumed tablespace was the same.
I run the following command and the problem resolved:
ALTER TABLE  TRANSACTION_DETAIL MOVE TABLESPACE USERS STORAGE (INITIAL 64K NEXT 1M);

Of cause, I have to do the same with related indexes after that Smile
Thanks all,
