Using DBMS_REDEFINITION.START_REDEF_TABLE I get SP2-0027: Input is too long
Hello, I am using the DBMS_REDEFINITION.START_REDEF_TABLE to migrate a large table to unicore data types. When I attempt this the list of columns is too long and it generates:
SP2-0027: Input is too long (> 2499 characters) - line ignored
Below is the procedure call. Is there a way to over come this?

Error with dbms_redefinition package?
Hi everybody!
I have a table ‘object_log’(it is partioned) .
I used dbms_redefinition to change its partion , and evrythink was ok.
When I tried to redefine this table for the second time it failed!
I run this script
BEGIN
DBMS_REDEFINITION.start_redef_table(
uname => 'TL_ETL',
orig_table => 'OBJECT_LOG',
int_table => 'OBJECT_LOG2');
END;
This is the error:

DBMS_REDEFINITION issue. ORA-12089 and ORA-42016
Hi all,
I need a little help understanding and using DBMS_REDEFINITION.
I have a table that I need to transform in a partitioned table, keeping all the indexes, constraints, primary and foreign keys unaltered. I found the DBMS_REDEFINITION and figured it is the best choice since I have to transform a table with more than 1 million records and a BLOB field. BTW I am working in a Windows 2003 R2 SP2 64bit environment on an Oracle 10.2.0.4 DB.
To test the procedure I used a smaller table, with fewer rows. This is what I did:
CREATE TABLE LONGO.ARRI_RICORSO as SELECT * from PRODUCTION.ARRI_RICORSO;
CREATE TABLE "LONGO"."ARRI_RICORSO2" ( "ARRI_ID" NUMBER(12) NOT NULL , "ARVB_ID" NUMBER(12) NOT NULL , "ARIN_ID" NUMBER(12),
"ARAV_ID" NUMBER(12), "ANAU_COD" VARCHAR2(4), "ANCO_ID" NUMBER(5), "ANNA_COD" CHAR(3), "ARRI_DATA" DATE,
"ARRI_PROT" VARCHAR2(20), "ARRI_D_TRASM" DATE, "ARRI_F_ESITO" CHAR(1), "ARRI_D_ESITO" DATE, "ARRI_PROT_ESITO" VARCHAR2(20),
"ERDO_ID_RICOR" NUMBER(12), "ERDO_ID_ESITO" NUMBER(12),
"ERDO_ID_PROVV" NUMBER(12)) TABLESPACE "USERS" PCTFREE 10 INITRANS 1 MAXTRANS 255 STORAGE ( INITIAL 0K BUFFER_POOL DEFAULT)
LOGGING PARTITION BY RANGE ("ARRI_DATA") (PARTITION "ARRI_RICORSO2_P1" VALUES LESS THAN (TO_DATE(' 2009-02-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS',

LOGGING NOCOMPRESS , PARTITION "ARRI_RICORSO2_P2" VALUES LESS THAN (TO_DATE(' 2009-03-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS',

( INITIAL 64K MINEXTENTS 1 MAXEXTENTS 2147483645 BUFFER_POOL DEFAULT) LOGGING NOCOMPRESS ,
PARTITION "ARRI_RICORSO2_P3" VALUES LESS THAN (TO_DATE(' 2009-04-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
TABLESPACE "USERS" PCTFREE 10 INITRANS 1 MAXTRANS 255 STORAGE ( INITIAL 64K MINEXTENTS 1 MAXEXTENTS 2147483645 BUFFER_POOL DEFAULT)
LOGGING NOCOMPRESS , PARTITION "ARRI_RICORSO2_P4" VALUES LESS THAN ...... ETC up to 60 partitions, one per MONTHSo I have the first table full and with constraints (a couple of NOT NULL values) and a second, completely empty, partitioned table.
I started off with:
exec dbms_redefinition.can_redef_table('LONGO', 'ARRI_RICORSO');that gave me the error
ERROR at line 1:
ORA-12089: cannot online redefine table "LONGO"."ARRI_RICORSO" with no primary
key
ORA-06512: at "SYS.DBMS_REDEFINITION", line 137
ORA-06512: at "SYS.DBMS_REDEFINITION", line 1479
ORA-06512: at line 1So I modified the script with:
exec dbms_redefinition.can_redef_table('LONGO', 'ARRI_RICORSO',dbms_redefinition.cons_use_rowid);
PL/SQL procedure successfully completed.OK! After this I launched:
SQL> exec dbms_redefinition.start_redef_table('LONGO', 'ARRI_RICORSO', 'ARRI_RICORSO2');
BEGIN dbms_redefinition.start_redef_table('LONGO', 'ARRI_RICORSO', 'ARRI_RICORSO2'); END;

ORA-06512: at "SYS.DBMS_REDEFINITION", line 1343
ORA-06512: at line 1...ok... Now I am stuck! What have I done wrong? I also read various documents that explained how to use correctly the procedure, but I can't understand why I am getting this error!
This is how the table is structured:
SQL> desc arri_ricorso
Name Null? Type
ARRI_ID NOT NULL NUMBER(12)
ARVB_ID NOT NULL NUMBER(12)
ARIN_ID NUMBER(12)
ARAV_ID NUMBER(12)
ANAU_COD VARCHAR2(4)
ANCO_ID NUMBER(5)
ANNA_COD CHAR(3)
ARRI_DATA DATE
ARRI_PROT VARCHAR2(20)
ARRI_D_TRASM DATE
ARRI_F_ESITO CHAR(1)
ARRI_D_ESITO DATE
ARRI_PROT_ESITO VARCHAR2(20)
ERDO_ID_RICOR NUMBER(12)
ERDO_ID_ESITO NUMBER(12)
ERDO_ID_PROVV NUMBER(12)ARRI_RICORSO2 is exactly the same, but with no data in it and with partitions....
Please help! :)
Thanks in advance!
P.s. I also added a primary key to both the tables. That is when I got the ORA-42016 error while attempting the exec dbms_redefinition.start_redef_table process ant not the ORA-12089 anymore...

Right idea, wrong implementation. You are passing the 'CONS_USE_ROWID' as the THIRD parameter instead of the FOURTH (col_mapping) parameter.
See the DBMS_REDEFINITION doc
http://docs.oracle.com/cd/B28359_01/appdev.111/b28419/d_redefi.htm#i998726
The 'OPTIONS_FLAG' is the THIRD parameter for the 'CAN_REDEF_TABLE' procedure
>
CAN_REDEF_TABLE Procedure
This procedure determines if a given table can be redefined online. This is the first step of the online redefinition process. If the table is not a candidate for online redefinition, an error message is raised.
Syntax
DBMS_REDEFINITION.CAN_REDEF_TABLE (
uname IN VARCHAR2,
tname IN VARCHAR2,
options_flag IN PLS_INTEGER := 1,
part_name IN VARCHAR2 := NULL);
>
But the 'OPTIONS_FLAG' is the FOURTH parameter for the 'START_REDEF_TABLE' procedure
>
START_REDEF_TABLE Procedure
Prior to calling this procedure, you must manually create an empty interim table (in the same schema as the table to be redefined) with the desired attributes of the post-redefinition table, and then call this procedure to initiate the redefinition.
Syntax
DBMS_REDEFINITION.START_REDEF_TABLE (
uname IN VARCHAR2,
orig_table IN VARCHAR2,
int_table IN VARCHAR2,
col_mapping IN VARCHAR2 := NULL,
options_flag IN BINARY_INTEGER := 1,
orderby_cols IN VARCHAR2 := NULL,
part_name IN VARCHAR2 := NULL);
>
This works for me:
exec dbms_redefinition.start_redef_table('SCOTT', 'ARRI_RICORSO', 'ARRI_RICORSO2', options_flag => dbms_redefinition.cons_use_rowid); -
DBMS_REDEFINITION dependent objects issue , please help.....
Hello Guru's,
Today I have tried with DBMS_REDEFINITION package, I'm successfully partitioning the existing table, but there are some dependent objects are missing after completing the redefinition package.
Im Using 11g R2.
Please assist me , in which stage it went wrong, Actually my table is have around 12 dependent procedures, functions, Synonyms how ever, after completing the redefinition when i query the all_dependancies I m getting only 9 objects with correct status.
Please suggest me that what happened to remaining 3 dependent objects. Its a bit urgent.
Steps I followed:
1.Created a bkp table of same as existing table A.
2.EXEC Dbms_Redefinition.Can_Redef_Table(USER, 'A'); ---No errors got.
3.DBMS_REDEFINITION.start_redef_table(uname => USER, orig_table => 'A',int_table => 'A_BKP'); ----No errors
4. dbms_redefinition.sync_interim_table(
uname => USER,
orig_table => 'A',
int_table => 'A_BKP'); ----No errors got.
5.Manually Added constraints on A_BKP what ever constraints on A .--- No errors
6. Manually Added Indexes on A_BKP what ever indexs are there on A columns ----No errors
7.EXEC DBMS_STATS.gather_table_stats(USER, 'A_BKP', cascade => TRUE); ---No errors
8.dbms_redefinition.finish_redef_table(
uname => USER,
orig_table => 'A',
int_table => 'A_BKP'); ----No errors
9. Manually Droped A_BKP table
10. Manually Renamed all constraints and Indexex to the original names -----No errors
11. Queried Select count(*) from A;
Then I queried in all_dependencies, now there is mis match between before partitioned table dependencies and after ,
Please tell me whats wrong with this steps , its a bit urgent, any fruther steps to be taken ?No I have checked that missing objects there are present in the DB and when i query in All_dependancies with that referenced name, it will giving less rows than original

Please answer these questions.....Urgent
Q You are using Data Guard to ensure high availability. The directory structures on the primary and the standby hosts are different.
Referring to the scenario above, what initialization parameter do you set up during configuration of the standby database?
db_convert_dir_name
db_convert_file_name
db_dir_name_convert
db_directory_convert
db_file_name_convert
Oracle 9i Administration, Question 1 of 12
Q What facility does Oracle provide to detect chained and migrated rows after the proper tables have been created?
The RDBMS cannot detect this. It must use regular export and import with compress=y to remove chained and migrated rows as part of the regular database.
The UTLCHAIN utility
The DBMS_REPAIR package
The ANALYZE command with the LIST CHAINED ROWS option
The DBMS_MIG_CHAIN built-in package
Q While doing an export, the following is encountered:
ORA-1628 ... max # extents ... reached for rollback segment ..
Referring to the scenario above, what do you do differently so that the export is resumed even after getting the space allocation error?
Use the RESUMABLE=Y option for the export.
Run the export with the AUTO_ROLLBACK_EXTEND=Y option.
Increase the rollback segment extents before running the export.
Use THE RESUME=Y option for the export.
Monitor the rollback segment usage while the export is running and increase it if it appears to be running out of space.
Q
The DBCA (Database Configuration Assistant) prompts the installer to enter the password for which default users?
SYS and SYSTEM
OSDBA and INTERNAL
SYSOPER and INTERNAL
SYS and INTERNAL
SYSTEM and SYSDBA
Q You are designing the physical database for an application that stores dates and times. This will be accessed by users from all over the world in different time zones. Each user needs to see the time in his or her time zone.
Referring to the scenario above, what Oracle data type do you use to facilitate this requirement?
DATE
TIMESTAMP WITH TIME ZONE
TIMESTAMP
DATETIME
TIMESTAMP WITH LOCAL TIME ZONE
Q Which one of the following conditions prevents you from redefining a table online?
The table has a composite primary key.
The table is partitioned by range.
The table's organization is index-organized.
The table has materialized views defined on it.
The table contains columns of data type LOB.
Q An Oracle database administrator is upgrading from Oracle 8.1.7 to Oracle 9i.
Referring to the scenario above, which one of the following scripts does the Oracle database administrator run after verifying all steps in the upgrade checklist?
u8.1.7.sql
u81700.sql
u0900020.sql
u0801070.sql
u0817000.sql
Q What command do you use to drop a temporary tablespace and the associated OS files?
ALTER DATABASE TEMPFILE '/data/oracle/temp01.dbf' DROP;
ALTER DATABASE DATAFILE '/data/oracle/temp01.dbf' DROP;
ALTER DATABASE TEMPFILE '/data/oracle/temp01.dbf' DROP INCLUDING DATAFILES;
ALTER DATABASE DATAFILE '/data/oracle/temp01.dbf' DROP CASCADE;
ALTER DATABASE DATAFILE '/data/oracle/temp01.dbf' DROP INCLUDING CONTEN
Q You wish to use a graphical interface to manage database locks and to identify blocking locks.
Referring to the scenario above, what DBA product does Oracle offer that provides this functionality?
Oracle Expert, a tool in the Oracle Enterprise Manager product
Lock Manager, a tool in the base Oracle Enterprise Manager (OEM) product, as well as the console
Lock Manager, a tool in Oracle Enterprise Manager's Tuning Pack
The console of Oracle Enterprise Manager
Viewing the Lock Manager charts of the Oracle Performance Manager, a tool in the Diagnostics Pack add on
Q CREATE DATABASE abc
MAXLOGFILES 5
MAXLOGMEMBERS 5
MAXDATAFILES 20
MAXLOGHISTORY 100
Referring to the code segment above, how do you change the MAX parameters shown?
They can be changed using an ALTER SYSTEM command, but the database must be in the NOMOUNT state.
The MAX parameters cannot be changed without exporting the entire database, re-creating it, and importing.
They can be changed using an ALTER SYSTEM command while the database is open.
They can be changed in the init.ora file, but the database must be restarted for the values to take effect.
They cannot be changed unless you re-create your control file
Q You need to change the archivelog mode of an Oracle database.
Referring to the scenario above, what steps do you take before actually changing the archivelog mode?
Execute the archive log list command
Start up the instance and mount the database but do not open it.
Start up the instance and mount and open the database in restricted mode.
Kill all user sessions to ensure that there is no database activity that might trigger redolog activity.
Take all tablespaces offline
Q You are experiencing performance problems due to network traffic. One way to tune this is by setting the SDU size.
Referring to the scenario above, why do you change the SDU size?
A high-speed network is available where the data transmission effect is negligible.
The application can be tuned to account for the delays.
The requests to the database return small amounts of data as in an OLTP system.
The data coming back from the server are fragmented into several packets.
A large number of users are logged on concurrently to the system.
Q When interpreting statistics from the v$sysstat, what factor do you need to keep in mind that can skew your statistics?
Choice 1 The statistics are static and must be updated by running the analyze command to include the most recent activity.
Choice 2 The statistics are only valid as a point in time snapshot of activity.
Choice 3 The statistics gathered by v$sysstat include database startup activities and database activity that initially populates the database buffer cache and shared pool.
Choice 4 The statistics do not include administrative users.
Choice 5 The statistics gathered are based on individual sessions, so you must interpret them based on the activity and application in which the user was involved at the time you pull the statistics.

Choice 5 The statistics gathered are based on individual sessions, so you must interpret them based on the activity and application in which the user was involved at the time you pull the statistics.
Q You want to shut down the database, but you do not want client connections to lose any non-committed work. You also do not want to wait for every open session to disconnect.
Referring to the scenario above, what method do you use to shut down the database?
Choice 1 Shutdown abort
Choice 2 Shutdown immediate
Choice 3 Shutdown transactional
Choice 4 Shutdown restricted sessions
Choice 5 Shutdown normal
Q What step or steps do you take to enable Automatic Undo Management (AUM)?
Choice 1 Create the UNDO tablespace, then ALTER SYSTEM SET AUTO_UNDO.
Choice 2 Use ALTER SYSTEM SET AUTO_UNDO; parameter.
Choice 3 Add UNDO_MANAGEMENT=AUTO parameter to init.ora, stop/start the database.
Choice 4 Add UNDO_AUTO to parameter to init.ora, stop/start the database, and create the UNDO tablespace.

When transporting a tablespace, the tablespace needs to be self-contained.
Referring to the scenario above, in which one of the following is the tablespace self-contained?
Choice 1 A referential integrity constraint points to a table across a set boundary.
Choice 2 A partitioned table is partially contained in the tablespace.
Choice 3 An index inside the tablespace is for a table outside of the tablespace.
Choice 4 A corresponding index for a table is outside of the tablespace.
Choice 5 A table inside the tablespace contains a LOB column that points to LOBs outside the tablespace.
You have experienced a database failure requiring a full database restore. Downtime is extremely costly, as is any form of data loss. You run the database in archive log mode and have a full database backup from three days ago. You have a database export from last night. You are not running Oracle Parallel Server (OPS).
Referring to the above scenario, how do you minimize downtime and data loss?
Choice 1 Import the data from the export using direct-path loading.
Choice 2 Create a standby database and activate it.
Choice 3 Perform a restore of necessary files and use parallel recovery operations to speed the application of redo entries.
Choice 4 Conduct a full database restore and bring the database back online immediately. Apply redo logs during a future maintenance window.
Choice 5 Perform a restore and issue a recover database command
You have two large tables with thousands of rows. To select rows from the table_1, which are not referenced by an indexed common column (e.g. col_1) in table_2, you issue the following statement:
select * from table_1
where col_1 NOT in (select col_1 from table_2);
This statement is taking a very long time to return its result set.
Referring to the scenario above, which equivalent statement returns much faster?
Choice 1 select * from table_1
where col_1 in (select col_1 from table_2 where col_1 = table_1.col_1)
Choice 2 select * from table_2
where col_1 not in (select col_1 from table_1)
Choice 3 select * from table_1
where not exists (select 'x' from table_2 where col_1 = table_1.col_1)
Choice 4 select table_1.* from table_1, table_2
where table_1.col_1 = table_2.col_1 (+)
Choice 5 select * from table_1

Fast Updates for 8 million records..!!
Hi All,
I was wondering is there any fast method for updating 8 million records out of 10 million table?
For eg :
I am having a customer table of 10m records and columns are cust_id, cust_num and cust_name.
i need to update 8m records out of 10m customer table as follows.
update customer set cust_id=46 where cust_id=75;
The above statement will update 8m records. And cust_id is indexed.
But if i fire the above update statement we'll face rollback segment problem..
Even if i use ROWNUM and commit after 100K records still its gonna take huge time and also i know CTAS will be lot lot faster but for this scenario i guess its not possible.. Right?
Any help is much appreciated...
Thanks.You didn't specify what version you're on, but have you looked at dbms_redefinition?
create table cust (cust_num number, constraint cust_pk primary key (cust_num), cust_id number, name varchar2(10));
create index cust_id_idx on cust(cust_id);
insert into cust values( 1, 1, 'a');
insert into cust values( 2, 2, 'b');
insert into cust values( 3, 1, 'c');
insert into cust values( 4, 4, 'd');
insert into cust values( 5, 1, 'e');
select * From cust;
create table cust_int (cust_num number, cust_id number, name varchar2(10));
exec dbms_redefinition.start_redef_table(user,'cust', 'cust_int', 'cust_num cust_num, decode(cust_id, 1, 99, cust_id) cust_id, name name');
declare
i pls_integer;
begin
dbms_redefinition.copy_table_dependents( user, 'cust', 'cust_int', copy_indexes=>dbms_redefinition.cons_orig_params, copy_triggers=>true, copy_constraints=>true, copy_privileges=>true, ignore_errors=>false, num_errors=>i);
dbms_output.put_line('Errors: ' || i);
end;
exec dbms_redefinition.finish_redef_table(user, 'cust', 'cust_int');
select * From cust;
select table_name, index_name from user_indexes;
You would probably want to run a sync_interim_table in there before the finish.
Good luck. -
Is there a way to re-org a range partitioned table?
I have a table which is range partitioned and till date of 2007 November.So the rest of the records are all in max partition.The size of the max is so huge (250 millions) it takes long time to split the max partition.And during the process of split the indexes on the table are getting invalid.So i am looking at a better way of doing the split.So is re-org possible on the max partition? During the process of re-org can i have the interim table with the new partitions?Hello,

Hi,
ORA-42016: shape of interim table does not match specified column mapping
How to resolve this error.Use DBMS_REDEFINITION.START_REDEF_TABLE to define how the old table maps to the new table. A couple of points to note - firstly (and probably obviously but it took a couple of failed attempts for the penny to drop), you need to specify all the columns. So, the parameter is a comma separated string like this:
col_mapping => 'col1 col1, col2 col2, col3 col3 ...... TO_LOB(colN) colN'
If you don’t get this right then you get:
ORA-42016: shape of interim table does not match specified column mapping
Secondly, there is an options_flag parameter which indicates how the mapping mechanism is done. There seem to be two methods - by primary key or by rowid with the former seemingly preferred over the latter where possible. -
HI ALL,
Is it possible to redefine table without primary key on table? because i m doing redefinition the table but it is not possible to create primary key on table and i m creating partition on that table
How it is possible without primary key to redefine it?
is it possible?
Thanks in advancehello,
So you are trying to redefine a table which has a primary key into partitioned table without a primary key, is that correct or I misunderstood you? If yes, then it's possible.
Here is an test example, i am using a table with a primary key and redefining into partitioned table, see if it helps you anyway and answers your question or not.

owner VARCHAR2 (30 BYTE) NOT NULL,
object_type VARCHAR2 (19 BYTE) NULL

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.

DDL for table & all its dependent objects
Hi,
I'm trying to perform online_redefinition of a table in Oracle 11g. After this the depedent objects like indexes & Primary Keys & Foreign Keys are missing. Can anyone help with a detailed step by step procedure to perform this online_redefinition.
I've performed the below steps
1) check whether table can be redefined online or not.
2) create the duplicate empty table using CTAS where 1=2 condition.
3) start the online redefiniton.
4) do the interim sync.
5) end the redifinition.
6) drop the duplicate table.
Regards
SuryaHi,
here are steps to consider:
1) check first if the table can be redefined online by using: DBMS_REDEFINITION.CAN_REDEF_TABLE
2) Create an intermediary table
3) Start the redefinition of the table using : DBMS_REDEFINITION.START_REDEF_TABLE
4) Copy dependents from the original table to the intermediary table using: DBMS_REDEFINITION.COPY_TABLE_DEPENDENTS
5) synchronize between the original and intermediate table : DBMS_REDEFINITION.SYNC_INTERIM_TABLE
6) Finish the redefinition of the intermediary table using: DBMS_REDEFINITION.FINISH_REDEF_TABLE
7) compare the "new" original table (used to be intermediary ) to the intermediary table (used to be old original)
8) Drop the intermediary table
I hope this helps you.

Change partitioned column range in range partioning in 11g
Hi All,
First of all , i am thankful to all of you for your help and suggestions in past. I have one new issue. I am using Oracle 11. There is one new functionality in 11g to do range paritioning while table creation and do daily partitioning.
CREATE TABLE TEST(
DUE_DAY DATE,
ID VARCHAR2(10 BYTE),
NAME VARCHAR2(25 BYTE)
PARTITION BY RANGE (DUE_DAY)
INTERVAL( NUMTODSINTERVAL(1,'DAY'))
PARTITION FIRST VALUES LESS THAN (TO_DATE('2012-02-05 12:00:00', 'SYYYY-MM-DD HH24:MI:SS')));
Now I found i create the partition range wrong so each partition has data from previous day 12:00 afternoon to today 12:00 afternoon instead of daily data from 00:00 am to 11:59 pm because i mentioned wrong range in partition.
I supposed to do like this:
CREATE TABLE TEST(
DUE_DAY DATE,
ID VARCHAR2(10 BYTE),
NAME VARCHAR2(25 BYTE)
PARTITION BY RANGE (DUE_DAY)
INTERVAL( NUMTODSINTERVAL(1,'DAY'))
PARTITION FIRST VALUES LESS THAN (TO_DATE('2012-02-05 00:00:00', 'SYYYY-MM-DD HH24:MI:SS')));
My question is: Is there any way i can change it now as table already has huge data in it, so i cant go with creation of another partitioned table with correct partition range? Please let me know your suggestions and comments to resolve this issue.
Regards
Dev

I don't think it is possible to achieve this without creating a new/an intermediate table.
If you can afford down-time, you should create new table, load data into it (in parallel with nologging), drop original table and rename new table.
If you want this switchover as online operation, you can use DBMS_REDEFINITION as follows:
