I am using compress partition for a large table.During the process I have used the below command for compress---
1. ALTER TABLE <TABLE_NAME> MODIFY PARTITION P1 COMPRESS;
However I found there are different command as below:-
2. ALTER TABLE <TABLE_NAME> MOVE PARTITION P1 COMPRESS;
What is the basic difference between these two as the compression is happening for both command.

I have a partitioned table - 128 partitions.
If I am not using data of many partitions in any way, will it affect my performance if I am firing select query that uses other/active partitions data.
How can I check when that partitioned was last accessed, also can I brought those inactive partitions offlie? If we can, what will be the advantages or disadvantages of that?
I am not able to exchange partition by following below steps:
drop table manu_tst_hashed_tbl_org;
drop table manu_tst_hashed_tbl_bkp;
drop table manu_tst_smpl_tbl;
CREATE TABLE manu_tst_hashed_tbl_org
[code]...
and getting the below erro:
ORA-14097: column type or size mismatch in ALTER TABLE EXCHANGE PARTITION
14097. 00000 - "column type or size mismatch in ALTER TABLE EXCHANGE PARTITION"
*Cause: The corresponding columns in the tables specified in the ALTER TABLE EXCHANGE PARTITION are of different type or size
*Action: Ensure that the two tables have the same number of columns with the same type and size.

difference between a user and schema on Oracle.By difference, I do not mean what is a user and what is a schema.
I understand that if we create a user, the schema gets created by default for that user. Does that mean that we cannot create a user/schema alone.
What if I just want to create a user and grant him some read access on an existing schema or just want to create a schema.
I've migrated from Oracle 9i to Oracle 11gR2, when i'm checking my application on Oracle 11gR2, i found that some of the query result are differed from the previous version of Oracle 9i, which is very illogical to me. I've checked the data for all related tables which are involved in one of the query. I've checked all indexes also. Still i'm not convinced that Oracle is doing anything wrong. I cannot recreate the whole scenario here, because of many tables involved in that query.
One of the sample query code.
select 'ProductMaster' producttype,e.schemecd,e.SCHEMESHORTDESC as SCHEMEDESC,to_char(e.schemefrdate,'dd/MM/yyyy')as schemefrdate, to_char(e.schemetodate,'dd/MM/yyyy') as schemetodate,e.mkid ,e.countrycd,e.statecd,e.districtcd,f.schemetype, a.productcd,a.packsizecd,a.packtypecd,a.sortorder1, a.countrycd,a.statecd,a.districtcd,a.p_uniqueid,a.mrp, (a.productcd ||'-'||b.countryname||'-'||c.statename||'-'||d.districtname|| ' -pkt.prc:'||a.pktprice ||' -mrp:'||a.mrp) as pcode

We have a table which is already partitioned by list and now we would like to add a subpartition.
Create table Item_mst
(
ccn varchar2(10),
Flag varchar2(1),
Item varchar2(10),
status varchar2(1)
)
[Code]..
Now I could like to alter the above table for adding a new subpartition on each partition on status.
ALTER TABLE Item_mst
MODIFY PARTITION Item_mst_Test
ADD SUBPARTITION Item_mst_Test_A VALUES ('A');
Above alter gives ORA-14253: table is not partitioned by composite range method.
However dropping and recreating the table with subpartitions is working fine.
But Dropping and recreating the table in production is very cumbersome as it has huge data and many indices.
While trying partition exchange feature of Oracle with 2 hash partitioned tables, I come to know that I can't directly exchange partitions between 2 partitioned tables
I have two hash partitioned tables , so to move partition data from one table to another will include-
1) Exchange from partitioned table to non-partitioned table.
2) exchange from non-partitioned table to new partitioned table.
But I am not sure in which hash partition my data will go in new partitioned table (data need to be moved has single key value on basis of which tables are partitioned),
Any impact is there if is do the following:
ALTER TABLE MY_TABLE TRUNCATE PARTITION P1 UPDATE GLOBAL INDEXES;
will there be any lock on the table during this operation? DML operations will work without any issue or not?
The table tb_hxl_hash have two partitions,when i exchange the second partition,it raise error,why?

We want to find out difference of data for some tables between current day & previous day. We can use query with minus operation but it will take lot of time since table size is in range from 200 to 500 GB. We have to do this exercise every day.

why I got 1079 records.how to show the two extra columns in the out put whcich are not used in GROUP BY clause.
