Create Partitioning to non-partitioning Table
Dear All,
I have a table which is non partitioning and it has about 20G data... If I want to partition this table with column say DATE_M,
Please can anyone suggest the best way to do this.
Thanks
So now in the partitioned table he creates one maxvalue partition and does exchange partition
That isn't the typical scenario. Typically you make the switch by using partitions for the NEW data and leave the existing data in the base range partition.
1. Existing app uses an unpartitioned table
2. New table is partitioned for NEW DATA
Assume you want monthly partitions (daily works the same). This is already April so there is already some April data.
So create the partitioned table so the base partition clause includes ALL of the data for April and before:
create table ipart
(time_id date
,cust_id number(4)
,amount_sold number(5))
partition by range(time_id)
interval(NUMTOYMINTERVAL(1,'month'))
(partition old_data values less than (to_date('01-may-2015','DD-MON-YYYY')))
Now you do the exchange with the unpartitioned table and all the current data goes into that 'OLD_DATA' partition.
New data for May and the future will have partitions created automatically.
That approach lets you ease into partitioning without disrupting your current processes at all.
As time goes by more and more of the data will be in the new monthly partitions. If you need to you can split that base partition
insert into ipart (time_id) values (sysdate - 90);
insert into ipart (time_id) values (sysdate - 60);
insert into ipart (time_id) values (sysdate - 30);
insert into ipart (time_id) values (sysdate);
commit;
alter table ipart split partition old_data
at (to_date('01-jan-2015', 'DD-MON-YYYY')) into
(partition old_data, partition JAN_FEB_MAR_APR);

Create partition table upto level 3
Hi All,
I want to create partition table using 3 columns. could you please tell me is that possible to do in oracle 11G. if can please tell me the way to create
PARTITION BY LIST (Acct_type)
SUBPARTITION BY LIST (PERIOD)
and needs to partition this using another column.( account_source)
please help me.
Regards,
krishHello,
3 levels of partition are not possible.
But perhaps you can combine 2 levels as follows:
With Oracle 11g you can use a virtual column:
CREATE TABLE F_ACCOUNT_PART
acc_type varchar2(100),
acc_source varchar2(100),
period date,
acc_type_source varchar2(201) as (acc_type||'_'||acc_source) )
PARTITION BY LIST (acc_type_source)
PARTITION FA_AA_ACC1 VALUES ('AA-ACC1') TABLESPACE USERS,
PARTITION FA_BB_ACC1 VALUES ('BB-ACC1') TABLESPACE USERS,
PARTITION FA_CC_ACC1 VALUES ('CC-ACC1') TABLESPACE USERS,
PARTITION FA_DD_ACC1 VALUES ('DD-ACC1') TABLESPACE USERS,
PARTITION FA_AA_ACC2 VALUES ('AA-ACC2') TABLESPACE USERS,
PARTITION FA_BB_ACC2 VALUES ('BB-ACC2') TABLESPACE USERS,
PARTITION FA_CC_ACC2 VALUES ('CC-ACC2') TABLESPACE USERS,
PARTITION FA_DD_ACC2 VALUES ('DD-ACC2') TABLESPACE USERS,
PARTITION all_other VALUES (DEFAULT) TABLESPACE USERS
)For versions prior to 11g you have to build a new column acc_type_source and fill the values cancatenated.

Unable to Create Partitioned Table
Hi All,
I was trying to create a partitioned table using following
Create table customers (custcode number(5),
Name varchar2(20),
Addr varchar2(10),
City varchar2(20),
Bal number(10,2))
Partition by list (city),
Partition north_India values (‘DELHI’,’CHANDIGARH’),
Partition east_India values (‘KOLKOTA’,’PATNA’),
Partition south_India values (‘HYDERABAD’,’BANGALORE’,’CHENNAI’),
Partition west India values (‘BOMBAY’,’GOA’);
It is throwing me an error
ORA-00922: missing or invalid option
Will you please tell me what is wrong with this query? Is it possible to create partitioned table using select statement (create table as select... Partition by...)?
Regards
~PravinPravin
Will you please tell me what is wrong with this query?I see 4 errors in the syntax. Therefore, I strongly suggest you to have a lock to this:
http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_7002.htm#i2146309
In addition, have a look to the error message. If I run your script in SQL*Plus it clearly shows where the problem is. E.g.:
SQL> Create table customers (custcode number(5),
2 Name varchar2(20),
3 Addr varchar2(10),
4 City varchar2(20),
5 Bal number(10,2))
6 Partition by list (city),
7 Partition north_India values (‘DELHI’,’CHANDIGARH’),
8 Partition east_India values (‘KOLKOTA’,’PATNA’),
9 Partition south_India values (‘HYDERABAD’,’BANGALORE’,’CHENNAI’),
10 Partition west India values (‘BOMBAY’,’GOA’);
Partition by list (city),
ERROR at line 6:
ORA-00922: missing or invalid option
Is it possible to create partitioned table using select statement?Yes. With the usual syntax.

Jdev 11g defect: Error creating partition table diagram

When attempting to drag partitioned table from DB connection onto a DB Diagram I'm getting the following exception. Anybody got similar experience?
Also every time I create new diagram or off-line DB JDev starts spinning at 40 - 50 % CPU and gets stuck, so I have to "kill" the process and restart it. After which it works fine. Could it be some JDK compatibility issue?

I need to create a partition table on target. I am currently using the below code, but it fails when the primary key on the source table has a primary key having more than one column. How can I get the first column name from the source table which can be used as the partitioning key?
create table texdatawarehouse.<%=odiRef.getInfo("TARG_NAME")%>
<%=odiRef.getColList("", "[COL_NAME]\t[DEST_WRI_DT] ", ",\n\t", "", "")%>
partition by range (<%=odiRef.getColList("","[COL_NAME]","","","PK")%>)
(partition a values less than (9999999999))
Thanks,
Dinesh.Hi Dinesh,
I am little bit confused with your reply...
Please correct me if I am on the wrong way..
The New Key you need to add to the target datastore.
then in interface select the target datastore (diagram tab)
in properties select the new key for update column.
I mean the partion will be created based upon the target column key.

I wish to create a table which may exist for next 100 years (how pessimistic I am), or perhaps for next 1000 years (now I have broadened my mind) in Oracle 9i (... ohh I can't help it). I want to create a partitioned table which will store data in partitions on yearly basis and sub-partitions on monthly basis, can I create a table with such partitions? If yes... then how?

How to create PARTITION table by?
I have huge table(1million records) which affect query performance. I notice it may help by partitioning it into two. One contains heavily used records and another the rest. However Partition By Range seems applicable to LESS THAN. What I want to do is something like ' EST_TYP in ('L','N')' etc.
Anyone can help? Any other advice on perf improvement? What I have done: 1>Reduced the no of EXT. 2>Created Index.

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.

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,
DBHi,
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.

Our requiremnt create the index on specific partition (ex : Test_prt2) only.Creating Partitioned Tables and Indexes
http://technet.microsoft.com/en-us/library/ms187526(v=sql.105).aspx
you can create a aligned index, the index will be spread over the filegroups
Create NonClustered Index IX_orders_aligned
On dbo.orders(order_id)
On test_monthlyDateRange_ps(orderDate);
OR
Unaligned parition, you can create index on any filegroups

Partition Table Query taking Too Much Time
I have created partition table and Created local partition index on a column whose datatype is DATE.
Now when I Query table and use index column in the where clause It is scaning all the table (Full scan) . The quey is :
Select * From mytable
where to_char(transaction_date, 'DD-MON-YY') = '01-Aug-07';
I have to use to_char function not to_date due to Front end application problem.Before we go too far with this, if you manually query with TO_DATE on the variable instead of TO_CHAR on the column, does the query actually use the index?
The TO_CHAR on the column will definitely stop Oracle from using any index on the column. If the query will use the index if you TO_DATE the variable, as I see it, you have three options. First, fix the application problem that won't let you use TO_DATE from the application. Second, change the application to call a function returning a ref cursor, get the date string as a parameter to the function, and do the TO_DATE in the function.
Third, you could consider creating a function-based index on TO_CHAR(transaction_date, 'dd-Mon-yy'). This would be the least desirable option, particularly if you would also be selecting records based on a range of transaction_dates, since it loses a lot of information that the optimizer could use in devising an efficient query plan. It could also change your results for a range scan.
