Need to copy partition table

Hi,
I want to take a backup of a table A with same structure (Including partition, data, index etc). when i try to take backup using below its not happening.
create table B
as
select * from A
Can anyone help me how to perform this operation.
Thanks,
NAga

Hi naga,
create table B
as
select * from AIs for data backup.
The indexes,partitions,primary key any other constraints will not be copied.
What you are looking for is actual AS_IS table backup.
You will have to do
exp username/password@dbname tables=(table_name) file=file_pathIf you want to retrieve then use import (imp) command.
Below is the link for your reference.

and if you are on 10g and above you cna use a enhanced version expdp

How to copy a table with LONG and CLOB datatype over a dblink?

Hi All,
I need to copy a table from an external database into a local one. Note that this table has both LONG and CLOB datatypes included.
I have taken 2 approaches to do this:
1. Use the CREATE TABLE AS....
SQL> create table XXXX_TEST as select * from XXXX_INDV_DOCS@ext_db;
create table XXXX_TEST as select * from XXXX_INDV_DOCS@ext_db
ERROR at line 1:
ORA-00997: illegal use of LONG datatype
2. After reading some threads I tried to use the COPY command:
SQL> COPY FROM xxxx/pass@ext_db TO xxxx/pass@target_db REPLACE XXXX_INDV_DOCS USING SELECT * FROM XXXX_INDV_DOCS;
Array fetch/bind size is 15. (arraysize is 15)
Will commit when done. (copycommit is 0)
Maximum long size is 80. (long is 80)
CPY-0012: Datatype cannot be copied
If my understanding is correct the 1st statement fails because there is a LONG datatype in XXXX_INDV_DOCS table and 2nd one fails because there is a CLOB datatype.
Is there a way to copy the entire table (all columns including both LONG and CLOB) over a dblink?
Would greatelly appriciate any workaround or ideas!
Regards,
Pawel.

Hi Nicolas,
There is a reason I am not using export/import:
- I would like to have a one-script solution for this problem (meaning execute one script on one machine)
- I am not able to make an SSH connection from the target DB to the local one (although the otherway it works fine) which means I cannot copy the dump file from target server to local one.
- with export/import I need to have an SSH connection on the target DB in order to issue the exp command...
Therefore, I am looking for a solution (or a workaround) which will work over a DBLINK.
Regards,
Pawel.

I need to copy data from a table in one database (db1) to another table in

Hi
I need to copy data from a table in one database (db1) to another table in another database (db2).
I am not sure if the table exists in db2,,,if it doesnot it needs to be created as well data also needs to be inserted...
How am I supposed to this using sql statements..?
I shall be happy if it is explained SQL also...
Thanking in advance

How many rows does the table contains? There are manyway you can achieve this.
1. export and import.
2. create a dblink between two databases and use create table as select, if structure doesnot exists in other database, if structure exists, use, insert into table select command.
example:
create a dblink in db2 database for db1 database.
create table table1 as select * from table1@db1 -- when there is no structure present
-- you need to add constraints manually, if any exists.
insert into table1 select * from table1@db1 -- when there is structure present.
If the table contains large volume of data, I would suggest you to use export and import.

Need help with importing data in partition table

Hi,
DB:8.1.7
OS: win 2003 server
I have a table which is 4.5GB in size. I created a new partition table,with local indexes. I exported the original table with all indexes,triggers and procedures.
After creating the empty partitioned table,i imported the dump file. The data isn't loaded. My questions are:
1) Will the indexes be overwritten?
2) Will the data go automatically in allocated partitions?
3) Do i need to export only table data ignoring indexes,triggers etc?
Best Regards,

1) Will the indexes be overwritten?Not if they already exist with the same name, or with the same logical definition (ie. same columns are already indexed)
2) Will the data go automatically in allocated partitions?Yes
3) Do i need to export only table data ignoring indexes,triggers etc?Do you need the triggers? do you need indexes that you haven't created manually? What about grants?

TIMESTAMP(6) Partitioned Key - Range partitioned table ddl needed

What is DDL syntax for TIMESTAMP(6) Partitioned Key, Range partitioned table

Not sure what you are asking. Are you asking how to create a partitioned table using a TIMESTAMP(6) column for the key?
CREATE TABLE TEST1
    USERID                 NUMBER,
    ENTRYCREATEDDATE     TIMESTAMP(6)
PARTITION BY RANGE (ENTRYCREATEDDATE) INTERVAL(NUMTOYMINTERVAL(1, 'MONTH'))
    PARTITION P0 VALUES LESS THAN (TO_DATE('1-1-2013', 'DD-MM-YYYY'))
)See my reply Posted: Jan 10, 2013 9:56 PM if you need to do it on a TIMESTAMP with TIME ZONE column. You need to add a virtual column.

Copying data into a partitioned table

Chaps,
We have a bunch of data tables that we are partitioning to improve performance. I am trying to find the best way to copy the data from the old tables into the partitioned ones.
For example, one take has about 45million rows. Performing a query on the entire table (one column is a timestamp) between two times takes about 6 minutes. I tried to do:
INSERT INTO NEWTABLE (SELECT * FROM OLDTABLE)
But its taking ages and when I checked on the progress in Enterprise Management Console I saw that it was performing a full table scan and ended up taking over 45 minutes! We have 2 more tables of this size and 2 others that are 5 times as large, so if I can make this go faster it would be brilliant!
I'm pretty sure that exporting the old table using 'exp' and then importing into the new partitioned table using 'imp' will not respect the partitioning?
So can anyone think of a quicker method that this?
Many thanks in advance,
Simon

1. Target table : alter table nologging
2. Target table : set indexes unusable
3. ALTER SESSION SET SKIP_UNUSABLE_INDEXES = TRUE
4. INSERT /*+ APPEND */ INTO TBL_TARGET SELECT * FROM TBL_SOURCE
4a. Hint /*+ PARALLEL */ will be probably also the option - it depends ...
5 Target table REBUILD INDEXES (probably with separate jobs for every partition).
6. ALTER TABLE LOGGING

Does Partitioning Tables need more Space

Hi,
Can some one tell me does Partitioned table need more space than a general tables(i.e with out any partition). If so what can be the percenatge difference.
Thanks

PaulHorth wrote:
don't forget that your data could be such
that certain partitions never get any rows in them - thus wasting space.
It is not having/not having any rows in a partition but rather init.ora parameter deferred_segment_creation setting. By default it is set to true, which means segment will be created on first insert.

Need to uncompress a hash partitioned table

I am working on oracle 11.1.0.7 database on solaris.
We had issues loading data into compressed tables, so we are trying to uncompress the tables and their partitions.
When I tried uncompressing a hash partitioned table, I am getting this error
SQL> alter table sample move partition SYS_1 nocompress;
alter table sample move partition SYS_1 nocompress
ERROR at line 1:
ORA-14260: incorrect physical attribute specified for this partition
I am able to move the table, it is just the nocompress option which doesn;t work.
SQL> alter table sample move partition SYS_1;
Table altered.
Can't we uncompress a hash partitioned table which is compressed?

You have to do it in two steps
alter table sample modify partition SYS_1 nocompress;
alter table sample move partition SYS_1;Best regards

FW HD Needs Repartitioning as "GUID Partition Table" to Install Leopard ?

I have the latest iMac and the latest LaCie Quadra HD which is currently split into 2 equal partitions which are formatted as Mac OS Extended (Journaled).
I want to install a bootable version of Leopard on the LaCie so I started up with the first iMac Install DVD.
The 2 partitions of the LaCie appeared with a red exclamation mark indicating they could not be used.
There was additional info stating that in order to use the LaCie it would have to be repartitioned in Disk Utility using the "GUID Partition Table".
Needless to say I aborted the installation and came here for help.
What is it all about ?

I wanted to "repair" my new iMac because the DW directory graph showed more than 30% of the items out of order!
If I wasn't used to DW I would have been worried as it sounds appalling but 2 years previous experience with a G3 iMac and a G4 eMac show that this is perfectly normal.
DW paints this frightening scenario yet Disk Utility passes the HD as perfectly OK and the actual performance experienced is fine.
On rebuilding the directories I have never noticed any improvement on what was already good performance !

Hello Vitor,
There are currently no known issues with version enabled tables that are partitioned. The merge operation may need to access all of the partitions of a table depending on the data that needs to be moved/copied from the child to the parent. This is the reason for the 'Partition Range All' step in the plan that you provided. The majority of the remaining steps are due to the hints that have been added, since this plan has provided the best performance for us in the past for this particular statement. If this is not the case for you, and you feel that another plan would yield better performance, then please let me know and I will take a look at it.
One suggestion would be to make sure that the table was been recently analyzed so that the optimizer has the most current data about the table.
Performance issues are very hard to fix without a reproducible test case, so it may be advisable to file a TAR if you continue to have significant performance issues with the mergeWorkspace operation.
Thank You,
Ben

"GUID partition table scheme" Can't install snow leopard on my mbp.

I have a mbp that is partitioned as half mac, half XP. I put in the snow leopard CD and came up with an error that said I could not istall snow leopard because my partition did not fit the "GUID partition table scheme". I followed the menues to the partition section of the disk utility. From there, I don't know what to do. I can't click on the "options" button to change to the GUILD thing. Do I need to repartition my entire mbp? Will this erase my other partition? And will it delete all my data? Any suggestions on what to do???

GUID partition table (GPT) or map is a set of instructions at the very begining of a storage drive to tell the hardware what partitions and formats are where on the drive.
A Intel Mac now requires a GPT to boot OS X as it uses EFI (Extensible Firmware Interface) which is a software firmware in a hidden EFI partition on the boot drive designed originally for copy protection by Intel. EFI loads into memory before OS X does, which can be seen if you have verbose mode activated upon boot time.
Setting up the boot drive with a GUID Partiton table WILL require backing up of all data off the machine and a complete erasure of ALL partitions on the drive, which includes ALL data, programs, operating systems and files not backed up off the machine previously.
Since a partition map is basically road directions, when it's destroyed so does go the partitions.
Also since you will be fresh installing 10.6, your free iLife won't tag along,, however you can erase/install 10.5 first then upgrade to 10.6 (no BootCamp) and that shoudl work.
Unfortunatly Mac's only now support Windows 7 in Bootcamp, however Windows 7 Pro (and above) will run XP programs natively or via free virtual machine XP downloaded from Microsoft, however since it's really not native, 3D games etc likely won't run very well.
If your not familiar or willing to take a chance, then I suggest you have someone else upgrade that machine.

I am unable to specify my own tag name. How can I change the tag name to one of my interest.
I need to create 3 partitions as told below
partitions:
/earth
/mars
/work
/earth and /work should be roughly equal in size, /mars should be twice the size of the others, if that is possible. If not 3 partitions of equal size will do.
Please, help me .
Thank you.

Exactly 1TB? Slightly under/slightly over?
Traditional Solaris disk labels are in VTOC format, but this format cannot describe disks larger than 1TB. So EFI labels must be used on disks larger than 1TB. Setup is slightly different.
Are these physical disks or LUNs from a SAN array? If they are array LUNS, it is often the case that they don't have a Sun label of any type. So...
#1 Apply a Solaris label
If the LUNS don't have a label (when selected in 'format', it gives a warning that no label is present and offers to apply a label immediately). When run non-interactively, format assumes "yes" for any questions. So all you'd have to do is select every disk to have it apply labels to any unlabled disk. Run 'format' once and find the highest number (maybe it's 50 for you). Create a text file that looks like this:
disk 1
disk 2
disk 3
disk 50Then feed that to format like this:
# format -f /tmp/disklist or whatever you've named the file.
#2 Apply the partition layout to all disks you want.
You asked if you should do the same procedure, but I don't see that you've actually done anything above other than print out the existing layout. Take one of your 48 drives and partition it the way you want manually (set the slices to the sizes that you want). Then you can copy the layout of that disk to others. You only want to do this between disks/LUNs of the same size. As an example, if you've explicitly partitioned c1t0d0 and you want to apply this to c1t1d0, do this:
# prtvtoc /dev/rdsk/c1t0d0s2 | fmthard -s - /dev/rdsk/c1t1d0s2Repeat for all of your other disks.

Can I use gpt to recreate/unerase a partition table? (Rebuild the GPT/GUID partition table?) I don't want to do FILE recovery.

(Yes, I've googled a bunch and read threads like this one already.)
Can I use gpt or some other app to recreate/unerase a partition table? That is, how can I rebuild a disk's GPT/GUID partition table?) I don't want to do FILE recovery.
What happened: Instead of erasing a single partition off a disk with many partitions, the entire partition table was erased (using Disk Utility, w/o deleting the underlying files). Somehow the "Erasing a disk deletes all data on all its partitions." warning message was missed.
I have a copy of the output of df, with the number of blocks in each partition, from just prior to the erasure, so I should be able to recreate the GPT/GUID partition table. Editing the GPT with a hex editor is not feasible. Simply recreating the partitions with Disk Utility will overwrite the key filesystem tables on each partition, and I don't want to do that, plus Disk Utility doesn't allow me to specify exact partition sizes anyway.
Surely there's an app for rebuilding the partition table (other than emacs' hexl-mode!) for recreating/unerasing a partition table when the partition sizes and orders are known? I've looked at the advertising for a bunch of recovery software and none of them clearly indicate that they will do what I want.
I guess I can try using gpt on a copy of the reformatted drive I've made with dd, and see what happens. But perhaps someone knows of a tool that should do what I need, or knows if gpt is that tool or not.
There are answers and tools that will do FILE recovery - search for files and recover the ones that aren't fragmented or deleted. As far as I can find, they just look for files on the disk, and don't pay much, if any attention to the filesystem info or directory heirarchy, which in this case is valuable. Of course I could send it in to DriveSavers, or the like. But none of that seems necessary, and the scavenging file recovery apps won't do the job well,
E.g. some are mentioned here:
I don't want to do FILE recovery.
Thanks for any help.
The links in this post are to pages describing the underlined term, e.g. the man pages for df and gpt.

Aperture has the ability to work with files in their existing location. They are called "referenced masters." When you import images, you should select the "In their current location" in the "Store Files:" drop down box. Have a read of the documentation for full specifics. Unsure how you can resolve your duplication; might be some work but next time have a read of the manual first
Information for versions is stored in the Aperture database (library file). The masters can be inside the library file itself, or they can be somewhere else.

Partition an Non Partition Table in 11.2.0.1

Hi Friends,
I am using Oracle 11.2.0.1 Oracle Database.
I have a table with 10 Million records and it's a Non Partitioned Table.
1) I would like to partition the table (with partition by range ) without creating new table . I should do it in the existing table itself (not sure DBMS_REDEFINITION is the only option ) (or) can i use alter table ...?
2) Add one partition which will have data for the unspecified range.
Please let me know the inputs on the above
Regards,
DB

Hi,
what is the advantage of using DBMS_REDEFINITION over normal method (create partition table,grant access,insert records)You can't just add a partition in a non-partitioned table. You need to recreate existing table to have it partitioned (you can't just start adding new partitions to existing non-partitioned table). Advantage of dbms_redefinition is that it is online operation to re-create an existing table and and your data always remains available during table recreation
I would like to know how to copy the object privileges,constraints,indexes from Non Partitioned table (sales) to Partitioned table (sales_part) which i am creating. will >DBMS_REDEFINITION.COPY_TABLE_DEPENDENTS help on this?First you need to tell us what method you are using to partition an existing table? If you are using dbms_redifiniiton, you really don't need to worry about triggers, indexex or constraints at all. Just follow any document which explains how to use dbms_redifinition. Dr. Tim has done a lot of work for dummys like us by writing documents for us. Follow this document.
http://www.oracle-base.com/articles/misc/partitioning-an-existing-table.php
If so can i use DBMS_REDEFINITION.COPY_TABLE_DEPENDENTS alone for copying the table dependents alone after i create partition table (or) it should be used along with >DBMS_REDEFINITION.START_REDEF_TABLE only?See above document which i mentioned.
