I want to move data from one partition to another partition in a same table.
Ex: Table A has Partitions P1 and P2. I want to move data from P1 to P2.
Is this is possible?
I have a range partitioned table with one lob column. Each partion is on a separate tablespace except two partitions which are on same tablespace. Now I want to move a partition from one tablespace to another tablespace along with lob data. By using a simple alter table move partition will also move the lob data or there is some special procedure to adopt.

View 8 Replies View RelatedI have to move the data from a Varray column to a table.
Lets say I have created a Varray as described below,
create or replace TYPE "BT_TYPE" AS OBJECT (
R_ID NUMBER,
P_EVENT VARCHAR2(100))
/
create or replace TYPE "BT_VR" AS varray(20) of BT_TYPE
/
And I have a used this Varray as the column datatype in table
Create table BT_MASTER(
BT_ID_SEQNUMBER(5),
BT_DETAILBT_VR);
And this table contains data.
I want to move the data in the VARRAY column BT_DETAIL to another table. I have create a staging table BT_STG which contains a surrogate key column and the columns from the VARRAY. I am creating this staging table at run time.
Create Table BT_STG(
BT_STG_ID NUMBER(5),
R_ID NUMBER(5),
P_EVENT VARCHAR2(100)
);
One way to create this staging table is to query the data dictionary views to get the VARRAY object's columns, datatyeps and create it.
Is there any other simpler way by which I could create a table similar to a VARRAY/Object?
Something similar to,
create table test as select * from BT_VR
We would like to remove the partitions from a particular table. The table in question has 12 partitions. Based on some initial investigation, I've come up with the following options. because the table we going to remove partition will have millions of records so on considering the db downtime we are looking for a alternative way. Is there a better way?

We are planning to create the final table in following ways.
1. Create n number of final tables.
2. Create n number of final tables with partitions based on the primary key value in staging table.
3. Create single final table with partition based on the primary key value staging table.

View 9 Replies View RelatedWe have Exadata -V2 quarter rack with High Performance Disks. We applied EHCC's various compression methods on some of the table's partitions.
Now we are setting up Exadata Expansion Rack - High Capacity Disks. Post implementation, we would be moving older partitions to new Expansion Rack wherein compressed partitions are also included.
In this case, would there be any impact on the compression ratio as the expansion rack is having high capacity disks.
And, moving partition method would be same as it is for non-exadata database i.e. "alter table <table_name> move partition
<partition_name> tablespace <tablespace_name>"
Can i alter the table to create partition on non partition table, i have tried and could not create it. Do we have some other means to do it as this is the live table and cannot drop them else will lose the data.

We have this archicture:
OLPT DB --> OLPT DB (Physical Standby, active dataguard) --> Data warehouse DB
We only allowed to connect to OLPT DB (Physical Standby, active dataguard) from Data warehouse DB. If there is possibility to use some of Oracle "native" method of data extraction (replication) from OLPT DB (Physical Standby, active dataguard) to Data warehouse DB.
As far as I know we cannot create materialized view log in OLPT DB (Physical Standby, active dataguard) in order to do data replication, but maybe there is some others ways?

I have to move data from old tables into new tables. I use a sqlplus script and execute multiple 'insert from select'. I thought the SQL statements are executed in sequence, one after the other. I run into this problem: Let's take this script for an example
insert into A (a,b,c,....
select a,b,c......
from X;
insert into B (a,b,....
select a,b,....
from A joined with Y;
commit;
After executing the script in our development DB
select count (*) from A
returns 200
When the script is executed in production, A table record count is 5
select count (*) from A joined with Y; (used in the second insert)
returns 200.
It seems that the two statements are executed at the same time and table A is not fully populated when the select in statement two is executed.I suspect this is due to parallel execution in production.
Will executing
ALTER SESSION DISABLE PARALLEL DML;
ALTER SESSION DISABLE PARALLEL QUERY ;

I have compare a specific query EXPLAIN PLAN at partition table and non-partition table. both tables data is same. Is it true way or not?
The requirement details are as below,
1) The database contains static as well as transactional data for telecom domain.
2) We have to move region-wise data from one database to another.
3) There are around 10 regions.
4) The region wise data extraction from source db is based on around 40 to 50 tables. Rest of the tables contains static data & it will not change.
5) The volume is around 1 million subscribers per region.
6) The migration is required because
a) The client is upgrading its base product which uses this database
b) There is a change in structure of static tables
c) Hardware upgrade
d) The client want to start with single region on new database & rest of the regions will be operated from old database.
7) Keep execution time to very minimum.
I am thinking to have solution as below,
1) Create destination database with upgraded db structure (as mentioned in 6b)
2) Create database links to access source db in destination db.
3) Write SQL queries to fetch data from all the respective tables for a specific region
4) Write separate PL/SQL blocks for each table to fetch data from source db & insert into respective table in destination db
a) Use FOR ALL & bulk collect to improve the performance
b) Divide table data into multiple chunks & execute parallel batches (around 10) to insert the data
5) Validate pre & post counts to verify the success of migration
I have database A and B , we are strictly restricted to not to create any DB links between these database. In database A based on complex logic we in a stored procedure we populate the data to table type..now dot net will take this table type data and insert the same in database B.
Question here :
1.When we try to bulk collect all the data into table type , i am getting error operand exceeds limit, but it is mandate to put all data in one short to table type as dot net will take that and insert into B database.
2.Is there any good logical method to achieve this in a simple way.
I have two tables with almost the same columns. Table A has 50 columns, Table B has 51 columns, which are defined exactly the same except one more column as LOAD_TIME.
Is there any easy way for me to move the data from Table A to B? the Extra column LOAD_TIME will be set as current system time. All I want is to avoid list all 50 column names. The following SQL has error ORA-00923 error.
INSERT INTO TB_B
SELECT *, sysdate from TB_A;
i made a master-deatil data block and when i completed all field on master-data block i can`t move to data block detail.
when i press (TAB OR ENTER) on last field, the cursor go back to first field.
I am trying to move data from one schema in database A to another schema in database B and only move data not others (procedure, view, function). What is the best way to do it? I am thinking database link then insert into select from database link. Is there a better way?
