Type logic Partition of an existing table
Dear all,My database is 10gr 2 and Linux is the operating system.
One of my table in the production database is huge and contains lots of data. Table is growing daily. There are many queries that users run on this table and the selection criteria is normally the date of entry of the registration, it's an Entrty_Date field with the date data type.
I want a partition logical on this table in such a way, the table name remains the same, and data are logically partitioned.
As if the Entry_Date is from 2005, a partition is made on criteria:
2005-2006
2006-2007
.
.
2011. at the request of the user for records having entry date > 2011... the query is made only this piece of the table, which makes the fast query.
I hope that I am able to make you understand my problem. If its possible in Oracle please let me know the name of the method and I'll RND on this one. And I have to do it on an existing table that contains a lot of data.
Thank you
Imran
Hello
You can do this

You get this error because your edit statement has an invalid syntax. In addition, you cannot partition a table that is not already configured for partitioning!
You have to physically re-create the partitioned table in order to add new partitions to it.

How add us partition on an existing table?
Hi gurus,
What would be the best way to add a partition to an existing table?
Is there a simple documentation for example?

Was it something you were ask in an interview?
You cannot add a partition to a table unless this table is a partitioned table.
The table is already partitioned? If so, after the DDL.
The Oracle documentation has examples of adding partitions to a table that is already partitioned
Adding Partitions
This section explains how to manually add partitions of a partitioned table and explains why partitions can be added specifically for partitioned more indexes.
Adding a Partition to a partitioned Table range
Use of the
ALTER
TABLE
...ADD
PARTITION
statement to add a new partition at the end 'high' (the point after the last existing partition). To add a partition at the beginning or in the middle of a table, use theSPLIT
PARTITION
clause. -
Partitioning of an existing Table using the EXCHANGE PARTITION
Hi all
I have one unpartitioned table I partitioned by Exchange, this table has several indexes and constraints (primary and foreign).
ALTER TABLE notpart_table ADD ( CONSTRAINT PK_KCESPITI PRIMARY KEY (K_CESP, TIPORD) USING INDEX TABLESPACE TBLS_CONTA, CONSTRAINT FK_KCONTO_CE FOREIGN KEY (K_CONTO) REFERENCES xxxx (K_CONTO)); CREATE INDEX IX_NFATTURA_CE ON notpart_tab (ANNO_FATTURA, K_REGISTRO, K_REGFA, TIPORD) TABLESPACE TBLS_CONTA;
after Create a partitioned Table Destination
notpart_table2, I created the same constraints and indexes defined in notpart_table
When I run
ALTER TABLE notpart_table2 EXCHANGE PARTITION PART_notpart_table2 WITH TABLE notpart_table WITHOUT VALIDATION UPDATE GLOBAL INDEXES;
I get: ora-02266
Why?
Thanks in advance for any help

It is not exactly what you have. Very probably not partitioned table, you are partitioning is the parent to another table table:
SQL > create table tbl1 (id number)
2.Table created.

3 primary key
4.Modified table.
SQL > create table tbl2 (id number)
2.Table created.

5.Modified table.

If so, of the foreign key and recreate it pointing to the partitioned table as parent after finished partitioning the table.

The easiest way is to simply create a new table and INSERT the data into the it from the old table. You will need a window of failure for the operation. After the new table is filled you can rebuild the constraints and indexes, rename/move the original table and rename the new table to the old name.
You can also export the table data and import it into a new partitioned table.
The short answer is: ALL of the data needs to be moved to new segments. IF the existing data are old and ready to be archived then now is the time to do it. Simply move only the data in the new table.

Hello
I want to archive a database due to too much data into DB everymonth, so I have to delete the records from the previous month, which is about 4 million.
Can someone give me idea to delete records as soon as possible. My opinion is to create the partition on the table and drop the partition once he becomes older.
But if I want to introduce the partition then I have to create a partition in an existing table. So please give me the best way to introduce the partition of the existing table.
It would really help that may suggest meanings.
Thank you

Need to create the Partition in the history table
Hello
I have an audit table that stores the data for the last 8 years in it and the customer wants to retain the data for the last 8 years. Now as adding data to this table is increasing, there is a delay in execution of report which are acquired by querying on this table.
Basically, they go a from date and to date. Then these date are compared with two columns of dates in the table. The condition of the query will be as below
TRUNC (NVL (DATE1, DATE2)) > = TRUNC (TO_DATE (?, ' dd/mm/yyyy ""))
AND TRUNC (NVL (DATE1, DATE2)) < = TRUNC (TO_DATE (?, ' dd/mm/yyyy ""))
Users can query for any date range.
I am thinking of creating a Partition of the range on this table for each month during the 8 years of data. Please suggest on the question of whether I should use partition interval range to make it more effective. And would also create an Index on this partition for the above two day columns.
12 (months) SO * 8 (years) = 98 would be created partitions. This will not overload the schema of database/Tablespace? Y at - it another effective way to set the table.
Please suggest and let me know for any clarification.
There are 2 approaches (but not limited to 2) to create the Partition on an existing table:
Note: There is no ALTER TABLE statement to convert a heap table to a partitioned table.
1. create a temporary Partitioned table with the same types of data in the column. Take a dump of the original table (HEAP) export and import the dump into the newly created partitioned intermediate table. After checking the data file the original and rename the interim even as the original table.
2 using the package Oracle DBMS_REDEFINITION automates the steps above from said (not exactly the same steps, however) and its done online - which means there is no required downtime, the original table may undergo DML operations during this process of redefinition. View partitioning of a table online with DBMS_REDEFINITION | Oracle instructor
According to my understanding if let us know as a partition interval then in April if there is an inserted record then it will create a new partition for the month of April will be of value less than 30 April 2014 "and all other documents created in April will pass under it"
Yes, it's a feature of 11g, which Oracle manages adding partitions as needed. In earlier versions DBA can add partitions manually from time to time. Reference www.gavinsoorma.com/2009/09/11g-interval-partitioning/
Here the reason for check the sent_out_datetime NVL will be NULL for few records, so in this case we want to get the records for dates of mapping them to received_datetime
In addition, try to replace the NVL with COALESCE and test it. This would help improve performance.

Partitioning of an existing partitioned table
Dear Experts,
I have a problem with redefinition of partitioning of an existing partitioned table. I have a parent table separated by a virtual column by range:
CREATE THE PARENT TABLE
(
PARENT_ID NUMBER NOT NULL,
INSERT_TIMESTAMP TIMESTAMP (6) NOT NULL,
CLOB PARENT_DATA NOT NULL,
BATCH NUMBER,
DATE of INSERT_DATE generated always as (TRUNC("INSERT_TIMESTAMP"))
)
LOB (PARENT_DATA) AS STORE NAVIGATION (ACTIVATE ONLINE STORAGE)
PARTITION BY RANGE (INSERT_DATE)
(
P2015_11 PARTITION VALUES LESS THAN (TO_DATE (' 2015-12-01 00:00:00 ',' SYYYY-MM-DD HH24:MI:SS ',' NLS_CALENDAR = GREGORIAN '))
CRAFT STORE (PARENT_DATA) AS (SECUREFILE
ACTIVATE THE ONLINE STORAGE),
P2015_12 PARTITION VALUES LESS THAN (TO_DATE (' 2016-01-01 00:00:00 ',' SYYYY-MM-DD HH24:MI:SS ',' NLS_CALENDAR = GREGORIAN '))
CRAFT STORE (PARENT_DATA) AS (SECUREFILE
ACTIVATE THE ONLINE STORAGE),
P2016_01 PARTITION VALUES LESS THAN (TO_DATE (' 2016-02-01 00:00:00 ',' SYYYY-MM-DD HH24:MI:SS ',' NLS_CALENDAR = GREGORIAN '))
CRAFT STORE (PARENT_DATA) AS (SECUREFILE
ALLOW ONLINE STORAGE,
PARTITION P_DEFAULT VALUES LESS THAN (MAXVALUE)
CRAFT STORE (PARENT_DATA) AS (SECUREFILE
ALLOW ONLINE STORAGE
))
);
and a child table partitioned by reference:
CREATE ACCOUNTS FROM THE TABLE. CHILD
(
PARENT_ID NUMBER NOT NULL,
DATAACC DATAACC_TBL,
CREATION_DATE DATE,
CONSTRAINT PARENT_D_E_PRT_FK
FOREIGN KEY (PARENT_ID)
(PARENT_ID) REFERENCES PARENT
ENABLE VALIDATE
)
NESTED TABLE, STORE DATAACC AS DATAACC_NT
PARTITION OF REFERENCE (PARENT_D_E_PRT_FK)
(
P2015_11 PARTITION,
P2015_12 PARTITION,
P2016_01 PARTITION,
PARTITION P_DEFAULT);
However, now in Oracle 12 c I am able to use the reference interval partitioning. How can I redefine the partitioning of the parent table so that there can be scope-level?
Thank you for your help.
Best regards, Atanas.
To change range partition to partition interval, the table should not have MAXVALUE partition... Follow the steps below to convert to partition interval
(1) check if all data of the MAXVALUE partition (p_default) using query below
SELECT COUNT (*) FROM parent PARTITION (p_default).
(2) if there is no trace in the p_default partition, drop the help below
ALTER TABLE DROP PARTITION parent p_default;
(3) use the clause SET INTERVAL to convert the range partition partition interval as below
ALTER TABLE parent SET INTERVAL (NUMTOYMINTERVAL(1,'MONTH'));
I guess, you have the range partition up to until, so there should not be any folder in p_default partition.

Creating a partitioned table to an existing table interval.
Hello
Is there a way I can create a partitioned table interval of an existing table using DEC? I know how to create a partitioned table in range.
create the table range_partitioned_table
partition by range (date_column)
(
partition p1 lower ((to_date (' 08/01/2012 ',' mm/dd/yyyy'))),
lower partition p2 values (to_date (' 09/01/2012 ',' mm/dd/yyyy')),
PN VALUES LESS THAN (MAXVALUE) PARTITION
)
AS SELECT * from existing_table;
Is there a similar way to the Interval partition an existing table?
create the table interval_partitioned_table
partition by range (date_column)
interval (provide the interval)
(
partition p1 lower ((to_date (' 08/01/2012 ',' mm/dd/yyyy'))),
partition p2 values less (to_date (' 09/01/2012 ',' mm/dd/yyyy')),
-PN SCORE VALUES LESS THAN (MAXVALUE)
)
AS SELECT * from existing_table;
For example:

2 partition by range (hiredate)
interval of 3 (numtoyminterval(1,'YEAR'))
(4)
5 score below p1 ((to_date (' 08/01/2012 ',' mm/dd/yyyy'))),

modify an existing table to selectively the partition interval range
I'm using Oracle 11.2.0.3.
I have an existing table that has parition interval range.
example:
Currently, we have the log of the table that is the partition of the range by day and we drop old parition to a week. However, we want to change this to persist the records in the table of WHICH = LEVEL "IMPORTANT."create table Log( ts date, level varchar2(20), scr varchar2(2000))PARTITION BY RANGE (TS) INTERVAL( NUMTODSINTERVAL(1,'DAY'))
What is the best way to achieve this?>
Is it possible to modify the existing interval partition table to add partition in the list?
>
Only using the DBMS_REDEFINITION to do online. And that always involves the creation of a "provisional" tableIf you have a window of failure just to create a new partitioned table the way you want to and INSERT the data into it. You should be able to use a DEC to do if you want. You may not use swap partition since all data must be physically moved.
>
Can we do list-interval partition table i.e. (with partition interval as partition sup)?
>
No - subpartitioning of interval is not currently supported.Here is the code example of a partitioned table by using the RANGE-interval LIST. It uses a VIRTUAL column, but you can ignore it for your use case
DROP TABLE mytable; CREATE TABLE mytable ( CREATION_DATE TIMESTAMP(6), LAST_MODIFIED_DATE TIMESTAMP(6), CREATION_DAY NUMBER(2) GENERATED ALWAYS AS (TO_NUMBER(TO_CHAR(CREATION_DATE, 'DD'))) VIRTUAL ) PARTITION BY RANGE (LAST_MODIFIED_DATE) INTERVAL(NUMTOYMINTERVAL(1, 'MONTH')) SUBPARTITION BY LIST (CREATION_DAY) SUBPARTITION TEMPLATE ( SUBPARTITION days_1_5 VALUES (1,2,3,4,5) , SUBPARTITION days_6_10 VALUES (6,7,8,9,10) , SUBPARTITION days_11_15 VALUES (11,12,13,14,15) , SUBPARTITION days_16_20 VALUES (16,17,18,19,20) , SUBPARTITION days_21_25 VALUES (21,22,23,24,25) , SUBPARTITION days_26_31 VALUES (26,27,28,29,30,31) ) ( PARTITION prior_to_2013 VALUES LESS THAN (TO_DATE('2013-01-01', 'YYYY-MM-DD')) )

How do I change my user type to be sufficient?

How do I change my user type to be sufficient?

You will need to create two new TYPEs. The one who has all the columns of the draw. The REQUESTOR table and the new column SCORE, then a TYPE which is an array of the first type.See example 12-22 using a Pipelined Table function for a Transformation in the PL/SQl language reference
http://docs.Oracle.com/CD/B28359_01/AppDev.111/b28370/tuning.htm#i53120
Here's the first part
-- Define the ref cursor types and function CREATE OR REPLACE PACKAGE refcur_pkg IS TYPE refcur_t IS REF CURSOR RETURN employees%ROWTYPE; TYPE outrec_typ IS RECORD ( var_num NUMBER(6), var_char1 VARCHAR2(30), var_char2 VARCHAR2(30)); TYPE outrecset IS TABLE OF outrec_typ; FUNCTION f_trans(p refcur_t) RETURN outrecset PIPELINED; END refcur_pkg; / CREATE OR REPLACE PACKAGE BODY refcur_pkg IS FUNCTION f_trans(p refcur_t) RETURN outrecset PIPELINED IS out_rec outrec_typ; in_rec p%ROWTYPE; BEGIN
Change
TYPE outrec_typ IS RECORD ( var_num NUMBER(6), var_char1 VARCHAR2(30), var_char2 VARCHAR2(30)); TYPE outrecset IS TABLE OF outrec_typ;
to include all the columns you need. Unfortunately, you have to manually list all the columns in the draw. The REQUESTOR table. If you think you need this same structure in other places you must create them as SQL types instead of PL/SQL types.
This example should be enough to show you how to modify your code to do something similar.

Casting table PL/SQL for the type of existing table and back ref cursor
Hello
I have the problem of casting a pl/sql table for the type of an existing table and turning the ref cursor to the application. Casting a ref cursor back and number of pl/sql table works well.
Declarant
< strong > TYPE type_table_name IS TABLE OF THE package_name.table_name%ROWTYPE; < facilities >
within the stored procedure, fill in a table of this type temp_table_name and returning the ref cursor help
< strong > results OPEN to SELECT * FROM TABLE (CAST (temp_table_name AS type_table_name)); < facilities >
generates an error. type_table_name is unknown in this distribution. According to me, this happens because of the declaration of the type locally.
Statement type_table_name inside the package specification does not work neither. Incredible, cast to the said dbms_sql.number_table to specify ref cursor back and dbms_sql package works very well!
< strong > CREATE TYPE type_table_name IS TABLE OF THE package_name.table_name%ROWTYPE; < facilities > deals without any error but creates an invalid type complain a reference to package_name.table_name
I don't want to declare every column in the table in type_table_name, because any change the table_name table would result in an inconsistent type_table_name.
Thanks in advance!
Edited by: user6014545 the 20.10.2008 01:04In any case you are right that there is a problem around anchorage (or maintaining) types of objects persistent to match the table structures, they may represent.
In the case you describe, you might be better off just open the refcursor immediately the using one of the techniques described in the http://www.williamrobertson.net/documents/comma-separated.html to manage the delimited list.
In the more general case where the line of treatment is necessary, you may make the pipeline functions.

Custom extension created logical partition
I created a custome partition by reducing 50 GB on my C drive. I named the new logical drive A
Now, I've exhausted 49 GB of this space and I need to extend it. Is possible to allocate more memory to a custom created existing logical partition?You cannot extend to the rear.
If you have another Partition after it, you need to remove the next Partition > extend your 50 GB in this space.
It's your choice.Read these tutorials:

Windows 7 RTM Installer deleted logical Partitions
My computer has two physical hard disks, each with multiple partitions. I did a custom installation of Windows 7 Professional RTM on the first hard disk, deleting an old primary partition containing Windows XP (which wouldn't start). However, after I installed Windows 7, ALL of my logical partitions on this disk had also disappeared. The Windows 7 Installer creates two primary partitions: the big partition I realized it, and a partition of 100 MB system reserved. (It is always not allocated the remaining space on the disk, as the new partition for Windows 7 was smaller than the Windows XP partition, which I've deleted.)
Former route:
GiB 250 NTFS (primary)
100 MiB ext2 (primary)
3 logical partitions (two ext3, a FAT32)
100 giB encrypted (primary)New layout:
100 MiB NTFS (primary)
149.9 giB NTFS (primary)
Unassigned 100 GiB
100 MiB ext2 (primary)
115,66 giB space (!) free where the logical partitions used to be
100 giB encrypted (primary)It seems that the installation program has decided to get rid of my extended partition. How can I recover my old logical partitions?
I managed to restore the missing partitions to aid CGSecurity's TestDisk, but it took some doing. Always, however, the fact that the Windows 7 Installer has deleted my partitions without asking confirmation is more worrying. That's what I guess happened:
Disc has 3 primary partitions and one extended partition, before starting the installation.
I told the installer to remove a primary partition and create a new one in its place to install Windows 7 on. He wanted to do a second primary partition, so she won another partition to delete. He didn't tell me that. He said he may need create additional partitions, but nothing has been said to delete those that already exist.
The Setup program has installed Windows 7, and my extended partition was gone (so logical partitions inside it were no longer accessible).I recommend strongly anyone install Windows 7 on a disk that contains several other partitions to create a partition for Windows 7 in advance (using the management of disks or DiskPart.exe), instead of using Setup to do. In this way, it will not create the partition of MiB 100 extra.

* Original title: 8 victory moved - Error Message: failed to create new partition...
I have Win XP on my Dell Dimension 5150, which is the dual boot with Linux Mint 12 Lisa and this is my favorite of the bunch.
