SUBPARTITION
When I run the table creation script, I get an error "ORA-00922: missing or invalid option. When I remove "INTERVAL (NUMTOYMINTERVAL (1, 'MONTH') 'it works fine.). I can't have a SUBPARTITION interval? I'm on Oracle 11.2
create table A_TEST (
DT DATE NOT NULL,
COL1_LIST varchar2(10))
PARTITION BY LIST (COL1_LIST)
SUBPARTITION BY RANGE (DT) INTERVAL(NUMTOYMINTERVAL(1, 'MONTH')
(PARTITION P1 VALUES ('A')
(subpartition SP1 VALUES LESS THAN (TO_DATE('01-10-2013', 'DD-MM-YYYY'))),
PARTITION P2 VALUES ('B')
(subpartition SP2 VALUES LESS THAN (TO_DATE('01-10-2013', 'DD-MM-YYYY')))
);
If you do not use the model suggested subpartition approach be "someoneelse" then you have a few syntax errors to fix. I think that the following is correct:
(
PARTITION P1 VALUES LESS THAN (TO_DATE (JANUARY 10, 2013 ',' DD-MM-YYYY ""))
(
SUBPARTITION SP_A VALUES ('A'),
SUBPARTITION SP_B VALUES ('B')
)
)

Rebuild partition/subpartition in parallel
Hello
I'm on 11 GR 2.
I have a composite partitioned table.
I have the index local bitmap created with the parallel clause. no degree specified and left to "DEFAULT".
I made the unusable index for some of the subparts.
Now, I want to rebuild the local indexes on the server.
alter index < index_name > < partition name > rebuild subpartition;
Given that these indices were initially created with parallel clause, do I need to explicitly specify the parallel clause for them to be rebuilt at the same time?
EDIT:
I've tested this and it seems that I have to specify the parallel clause explicitly for the index to rebuild at the same time. Without the parallel clause, the index used only a thread to do the work.
Mark as answer and closed.
Responded. We need to explicitly specify

SUBPARTITION to drop and add data give ora-14300
11.2.0.4
RHEL
create a table partitioned by date, sous-partitionnée by the key 2 N, Y values
Insert a record for sysdate, key_value = 'Y '.
Insert a record for sysdate, key_value = ' don't
2 subparts create ok.
Drop the subparts to this date where value = N.
Re-insert the record for sysdate, key_value = ' not and generates the error
ORA-14300: partitioning key in a score cards outside the maximum number of partitions "" ""
Manually add the subpartition (alter table add) high value N for the data to be inserted again for this partition.
Is this expected behavior? I can understand if the model was not there, but it is. Probably a quirk to treat the scores of void

Interval question partition and subpartition - range
11.2.0.4
(separate issue than my other storage)
You can partition a table by day apart and subpartition and then by a field ID, a sequential ID in single digits? I want a subpartition for each code. something lije
CREATE TABLE detail_tab
(prod_id NUMBER (6))
date of create_ts
)
PARTITION OF RANGE (create_ts) INTERVAL (NUMTODSINTERVAL(1,'DAY'))
SUBPARTITION BY RANGE (prod_id) interval (1)
Ive read the docs http://docs.oracle.com/cd/E18283_01/server.112/e16541/part_admin001.htm#insertedID5 but you see is not the one I want. IM thinking the closest, I can get to it is a hash range
OK - so FYI stock, you should have a LIMITED identity series: your "id" is probably in the ticker.
Oracle can manage thousands of partitions.
For example, to create a partitioned table range-list with each list being one, or several, stock ID. Just hardcode the IDs. Or generate the DDL from a table with a game master of ID.
Creation of segment use deferred for segments are not created until there are at least a lines for the subpartition.
Remember, however, you must handle everything by SEGMENT. This means the subpartitions. So all this rollilng off be for hundreds of ID stock.
You should analyze your processes to determine the "roll-off" exact criteria you need. Group stocks into the partition even if they can get out.
Also - you can use 'tricks' as the creation of CUSTOM symbols that truly represent AGGREGATE data from stocks of one or more.
We used to store weekly data by using a value DATE when markets aren't open yet. Activity on these dates were given aggregate rather than granular data.

Find the right Partition for swap Partiton when there are PARTITION and SUBPARTITION
Hi all
I have a small problem:
I want to find the right cause of partitions of the partition key. I have a partition and a Subpartition (sample - table in annex).
I leave the database to generate the partition (and name), the name is generated. I need to find for the exchange of partition
the right of Partition has cause of a given value of the partition key (in this case EVOD_PART_DATE and 20141101 value).
When I try to find the right partiton name, I would use generally not:
SELECT DISTINCT dbms_rowid.rowid_object(ROWID) data_object_id FROM F_CONTRACT_EVENT WHERE EVOD_PART_DATE = TO_DATE ('20141101','YYYYMMDD')Okay, I get 2 rows, I'm expecting one, but cause the result are the subpartions, I get this:
SELECT * FROM ALL_OBJECTS WHERE DATA_OBJECT_ID IN ( 155159,155154);
I see:
EVO_DM F_CONTRACT_EVENT SYS_SUBP4292 155159 155159 TABLE SUBPARTITION EVO_DM F_CONTRACT_EVENT SYS_SUBP4287 155154 155154 TABLE SUBPARTITION
But I don't want the subparts, I want the PARTITON!
The table:

Thanks for Berlin
First of all - the DOF you posted is INVALID - you do not specify a delayed segment creation for partitions. Specify you for the table.
Also, you must remove the DEFAULT value - 1 for the partitioning column. The value '-1' cannot be converted to a valid date for the virtual partitioning column value.» The default value is useless and will give confusion around the year exception err when the exception should actually provide a NULL value for a column not null.
The documentation explains how to use the EXCHANGE PARTITION and has the code example
Exchange a Partition of a partitioned Table interval
You can exchange of range partitions in a partitioned table interval. However, you must make sure that the partition of the interval was created before that you can swap partition. You can leave the database create the partition in the partition of the interval of locking.
The following example shows an Exchange partition for the
interval_salestable, range-partitioned using the monthly from partitions of 1 January 2004. This example shows how to add data to the table using charge Exchange partition for June 2007. Assume there is only a local index on theinterval_salestable and equivalent index have been created on theinterval_sales_june_2007table.LOCK TABLE interval_sales PARTITION FOR (TO_DATE('01-JUN-2007','dd-MON-yyyy')) IN SHARE MODE; ALTER TABLE interval_sales EXCHANGE PARTITION FOR (TO_DATE('01-JUN-2007','dd-MON-yyyy')) WITH TABLE interval_sales_jun_2007 INCLUDING INDEXES;Note the use of the
FORsyntax to identify a partition that has been generated by the system. The name of the partition can be used by querying the*_TAB_PARTITIONSview of data dictionary to find the partition system-generated name.Given that the last paragraph? That's what showed Solomon.
NOTE:-special attention to the FIRST paragraph. If you use segment carried OVER creating the partition you want to Exchange could NOT have been created yet.
Make SURE that you lock the partition as the example shows, or you will get an exception if it has not been created.
Also - we know NOT what PROBLEM you're trying to solve.
If you exchange a PARTITION of a table subpartitioned your working table should actually be partitioned using the SAME parttioning as the subparts in the source table:
See my response in this thread:
https://forums.Oracle.com/forums/thread.jspa?threadID=2482090&TSTART=30
In this thread I have provide the code example illustrating how the table should be created and made Exchange.

How to change the default attributes for an index for a subpartition without data in it
Hello
The use of oracle 11.2.0.3 attributes and modifydefault for a partition, for example the tablespace can but can not use the same syntax for a subpartition.
Is it possible to change the default attributes for a subpartition?
ALTER index RTRN_CUR_CONV_IDX change the default attributes for the subpartition SYS_SUBP64934 RTRN_PART_201505 tablespace
Thank you
Refer to the section of the doc "a Subpartition template editing.
http://docs.Oracle.com/CD/B28359_01/server.111/b32024/part_admin.htm#i1007904
A Subpartition template editing
You can change a model of a composite partitioned table subpartition by replacing it with a new model of subpartition. All subsequent operations that use the subpartition template (such as
ADDPARTITIONorMERGEPARTITIONS) will now use the new subpartition template. Existing subpartitions remain unchanged.If you change a subpartition of a range model * composite partitioned table, then of range partitions that have not yet been created will use the new subpartition template.
Use of the
ALTERTABLE...SETSUBPARTITIONTEMPLATEstatement to specify a new subpartition template. For example:You will need to 'fix' the new model as in the doc example.
By the example of partitions with just a line in them, we find the secondary partition with data correctly a tablespace name as expecetd, but 4 other secondary partitions always show the name of the default tablespace in user_ind_subpartitions.
Any idea whay and if can change
Change the template affects only the created NEW partitions/subpartitions. If you want existing subpartitions to a different tablespace, you will need to move it.

Subpartition change a table of scales
I'm on Oracle 11 g. I have a table that t partitioned SCALES (top level is put on the account id, nested is carried on the transaction date). Nested level has 3 SP1, SP2, SP3 subparts for each range of high-level account id. I want to load daily data in this table and try to use the EXCHANGE partition function to only change the first of the 3 subpartitions SP1, because it is the only newcomer partition data will in...
Q1. Am I correct that I can't share in the target T table in the upper level (account level)?
Q2. So if I'm right then I have Exchange subpartition level. My question is what should the DOF look like to WORK W table that will be exchanged? If the work W DDL table must be identical to the target T table (i.e., having the two scales) OR must the work table W be partitioned only on the beach on the date of the transaction? At the end for all this I want the target table to be partitioned as it was before the Exchange i.e. scales.
Q3. I am told that I can't share all the first subparts at once i.e. I have to loop through and taking sub partition exchange both. Is this fair?
Q3. Is it the right way, I'm on the creation of the table of work W I have an outer loop through the beaches of account id. For each account id range:
1 remove the index on W and truncate the work table W
2. Insert as Select * void target partition SP1 for this account is carried in W
3 insert the daily records newly arrived in W (now W has the fusion of old and new)
4. create the index the w
5 Exchange W with the sub specific partition name i., e name of SP1 for this range of account id
Q4. Help, please. with any other suggestions for making the most efficient possible. I am told that I have to make a partition of void at a time. Is this fair?
Sincerely
I have a table that t partitioned SCALES (top level is put on the account id, nested is carried on the transaction date).
Why - tell us the business reason for partitioning the table ID account first, and then the TRANSACTION DATE second.
This suggests that your queries are primarily by account id or account ID range, rather than the date of the transaction. Is this correct?
I want to load daily data in this table and try to use the EXCHANGE partition function to only change the first of the 3 subpartitions SP1, because it is the only newcomer partition data will in...
OK - then you load data into MULTIPLE processes.
Q1. Am I correct that I can't share in the target T table in the upper level (account level)?
Yes and no yes - you can exchange at the partition level. But no - your new data are NOT at the level of the score, that's ONE of the subpartitions.
Q2. So if I'm right then I have Exchange subpartition level. My question is what should the DOF look like to WORK W table that will be exchanged? If the work W DDL table must be identical to the target T table (i.e., having the two scales)
For subpartitions work table must correspond to the structure and will be a partitioned table that is partitioned to match the subparts of the main table.
See my example in this thread:
https://community.Oracle.com/thread/2484090?TSTART=30
The Oracle (VLDB and partitioning Guide) documentation has more examples:
http://docs.Oracle.com/CD/B28359_01/server.111/b32024/part_admin.htm#i1107555
Exchange a Subpartition of a *-range partitioned Table
The semantics of the
ALTERTABLE...EXCHANGESUBPARTITIONare identical to those described previously in "Exchange a Subpartition of a *-Hash Partitioned Table '.See the examples in the doc
Q3. I am told that I can't share all the first subparts at once i.e. I have to loop through and taking sub partition exchange both. Is this fair?
Yes and no yes - it's true. No - you can do that.
You can exchange an entire partition, even if it is sous-partitionnée, or you can swap a subpartition. But your new data being subpartition level you will need to make an exchange for each subpartition P1.
If your table is partitioned by date (instead of ID), you can load your work table (partitioned by account id) and then exchange the partition of high level of the ENTIRE page.
Q4. Help, please. with any other suggestions for making the most efficient possible. I am told that I have to make a partition of void at a time. Is this fair?
Yes - but as I said before if your table has been partitioned by date and sous-partitionnée by id so you could do a single Exchange.
Can't help with the indexes because you didn't post the DDL for the table and index, so we can see whether they are global or local. For some use cases you have Oracle automatically to update the index.
Learn by doing. Create some examples of paintings and try things.

SUBPARTITION nonexistent stats

Now I see num_rows and analyse in dba_tab_partions but not in dba_tab_subpartition.
Why?

Subpartition compresses with pctfree
Hello
How compress subpartition on exadata, by using "high motion" and pctfree 10 options?
I used this statement, but I get only ORA-14160: this physical attribute may not be specified for a table subpartition.
ALTER table table_name move subpartition subpartition_name PCTFREE 10 compress to request high;

https://support.Oracle.com/epmos/faces/UI/km/SearchDocDisplay.JSPX?ID=258597.1&type=document&DisplayIndex=1
The short version is: you cannot specify physical attributes such as compression for an individual subpartition. You will have to do for the whole score (or even the entire table).

Using PARTITION FOR / SUBPARTITION FOR the syntax to insert
We try to use PARTITION syntax for (or, better, SUBPARTITION of syntax) to insert into a table subpartitioned.
http://docs.Oracle.com/CD/E11882_01/server.112/e26088/sql_elements009.htm#i165979
This table is interval partitions DATA_ORIGIN_ID and list subpartitions on TABLE_NAME.08:26:46 GM_CS_CDR@oradev02> select * from v$version; BANNER -------------------------------------------------------------------------------- Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production PL/SQL Release 11.2.0.3.0 - Production CORE 11.2.0.3.0 Production TNS for Solaris: Version 11.2.0.3.0 - Production NLSRTL Version 11.2.0.3.0 - Production 5 rows selected.
First of all, an insert in base without specifying the partitions:
Check SUBPARTITION to a SELECT statement syntax:08:10:05 GM_CS_CDR@oradev02> insert into key_ids2 ( 08:11:51 2 DATA_ORIGIN_ID , 08:11:51 3 TABLE_NAME , 08:11:51 4 DUR_UK , 08:11:51 5 DUR_UK_ID ) 08:11:51 6 select 08:11:51 7 12 , 08:11:51 8 TABLE_NAME , 08:11:51 9 DUR_UK , 08:11:51 10 DUR_UK_ID 08:11:51 11 from key_ids where table_name = 'PART' 08:11:51 12 and rownum <= 10; 10 rows created.
But if we add a subpartition specification (to limit the locking to a single subpartition), we get a syntax error:08:19:43 GM_CS_CDR@oradev02> 08:26:45 GM_CS_CDR@oradev02> 08:26:45 GM_CS_CDR@oradev02> 08:26:45 GM_CS_CDR@oradev02> 08:26:45 GM_CS_CDR@oradev02> select count(*) from key_ids2 08:26:45 2 subpartition for(12,'PART'); COUNT(*) ---------- 10 1 row selected.

But by specifying explicit partition and subpartition works:08:14:58 GM_CS_CDR@oradev02> insert into key_ids2 partition for(14) ( 08:15:23 2 DATA_ORIGIN_ID , 08:15:23 3 TABLE_NAME , 08:15:23 4 DUR_UK , 08:15:23 5 DUR_UK_ID ) 08:15:23 6 select 08:15:23 7 14 , 08:15:23 8 TABLE_NAME , 08:15:23 9 DUR_UK||'!' , 08:15:23 10 DUR_UK_ID 08:15:23 11 from key_ids 08:15:23 12 where table_name = 'PART' 08:15:23 13 and rownum <= 10; insert into key_ids2 partition for(14) ( * ERROR at line 1: ORA-14108: illegal partition-extended table name syntax

Any ideas?
Thank you
MikeSupport of Oracle reproduced this issue. The resolution was to ensure cursor_sharing is set to "EXACT", we happened to use "SIMILAR" in this case due to a migration of 10 g and 11 g.

doubt in a table subpartitioning
Hi gems... good evening...
I have a table that was previously only range partitions.
Now I changed it to the partitioning composite range-hash.
There are 6 partition tablespaces namely TS_PART1, TS_PART2... TS_PART 6.
The default tablespace of the schema is TS_PROD.
The table had following structure previously:
create the table ORDER_BOOK
(
CUST_ID NUMBER (10),
PROFILE_ID NUMBER (10),
PRODUCT_ID NUMBER (10),
SUB_PROFILE_ID VARCHAR2 (25).
DATE OF CASHFLOW_DATE,
NUMBER (24.6) OF EARNINGS.
constraint ORDER_BOOK_PK primary key (CUST_ID, PROFILE_ID, PRODUCT_ID, SUB_PROFILE_ID, CASHFLOW_DATE)
)
partition by range (CASHFLOW_DATE)
(
partition values ORDER_BOOK_PART1 less (TO_DATE (January 1, 2003 ',' DD-MM-YYYY "")) tablespace TS_PART1;
partition values ORDER_BOOK_PART2 less (TO_DATE (January 1, 2006 ',' DD-MM-YYYY "")) tablespace TS_PART2;
partition values ORDER_BOOK_PART3 less (TO_DATE (January 1, 2009 ',' DD-MM-YYYY "")) tablespace TS_PART3;
partition values ORDER_BOOK_PART4 less (TO_DATE (1 January 2012 ',' DD-MM-YYYY "")) tablespace TS_PART4;
partition values ORDER_BOOK_PART5 less (TO_DATE (1 January 2015 ',' DD-MM-YYYY "")) tablespace TS_PART5;
partition values ORDER_BOOK_PART6 less (TO_DATE (1 January 2018 ',' DD-MM-YYYY "")) tablespace TS_PART6
)
;
create index ORDER_BOOK_IDX on ORDER_BOOK (PRODUCT_ID, CASHFLOW_DATE);
Now, I did the following steps to change the existing partitions to the new partitions composite range-hash:
Start
DBMS_REDEFINITION. CAN_REDEF_TABLE
(uname = > 'DEMO_TEST',)
tNom = > "ORDER_BOOK"
options_flag = > DBMS_REDEFINITION. CONS_USE_PK);
end;
/
create the table INTERIM_ORDER_BOOK
(
CUST_ID NUMBER (10),
PROFILE_ID NUMBER (10),
PRODUCT_ID NUMBER (10),
SUB_PROFILE_ID VARCHAR2 (25).
DATE OF CASHFLOW_DATE,
NUMBER (24.6) OF EARNINGS.
constraint INTERIM_ORDER_BOOK_PK primary key (CUST_ID, PROFILE_ID, PRODUCT_ID, SUB_PROFILE_ID, CASHFLOW_DATE)
)
partition of range (CASHFLOW_DATE)
SUBPARTITION by hash (CUST_ID)
model SUBPARTITION
(
SUBPARTITION SP1 tablespace TS_PART1,
SUBPARTITION SP2 tablespace TS_PART2,
SUBPARTITION SP3 tablespace TS_PART3,
SUBPARTITION SP4 tablespace TS_PART4,
SUBPARTITION SP5 tablespace TS_PART5,
SUBPARTITION SP6 tablespace TS_PART6
)
(values less than P1 (to_date('01-01-2003','DD-MM-YYYY')) partition,
values of partition P2 lower (to_date('01-01-2006','DD-MM-YYYY')),
values of partition P3 lower (to_date('01-01-2009','DD-MM-YYYY')),
partition P4 values less than (to_date('01-01-2012','DD-MM-YYYY')),
values for partition P5 lower (to_date('01-01-2015','DD-MM-YYYY')),
values of partition P6 lower (to_date('01-01-2018','DD-MM-YYYY')))
allow the movement of the line;
Start
dbms_redifinition.start_redef_table
(uname = > 'DEMO_TEST',)
orig_table = > 'ORDER_BOOK ',.
int_table = > 'INTERIM_ORDER_BOOK ',.
options_flag = > DBMS_REDEFINITION. CONS_USE_PK);
end;
/
Start
DBMS_REDEFINITION.finish_redef_table
(uname = > 'DEMO_TEST',)
orig_table = > 'ORDER_BOOK ',.
int_table = > 'INTERIM_ORDER_BOOK');
end;

After I did the index with the LOCAL clause is to say local indexes.
But the problem is that... at the beginning when there is only the range partitioning, then the data will tablespaces corresponding score.
But after editing the table, fill the array results in consumption of space in partition as well as the default tablespace storage.
I checked the size of the storage space. Since I came to know about it.
The output of the USER_TAB_SUBPARTITIONS is correct... each subparts are in the corresponding storage spaces.
But the primary partitions (USER_TAB_PARTITION) are in the default tablespace.
Please help me... thanks in advance...

Yes - so why is it a surprise?You have created a new table and storage for partitions has not specified then the default tablespace has been used. You did not specify tablespaces for subparts to each of them uses the specified tablespace.
Don't you see the difference between the original
partition ORDER_BOOK_PART1 values less than (TO_DATE('01-01-2003', 'DD-MM-YYYY')) tablespace TS_PART1,and the new
(partition P1 values less than (to_date('01-01-2003','DD-MM-YYYY')), -
How can I copy templates subpartition of a table to another table in the physical model of OSDM?
I need to create a relatively large number of subpartition templates and I have to do for several tables. They have all of the similar subpartitions.
Can I create templates for subpartition to a table and copy and paste those to the other tables?
Otherwise, there is no alternative workaround to avoid creating for each table subpartition templates?
I use v3.1EA3Hello
The expression of the interval you specified,
1)
(VALUES LESS THAN (1) PARTITIONis not a valid interval expression.
You must set the Expression of the interval 1.
If you want to generate the PARTITION VALUES LESS THAN clause (1), you should add a Partition for the Table object in the physical model and set its property to list the value to 1.

SUBPARTITION model COMPRESS NOCOMPRESS parameter
Hello
I am trying to create a table with subpartitions by already partitioned by list, list
I want to configure some of my subparts are compressed and the rest nocompressed.
but I could not find how to specify
I could specify whether the partition at all is compressed or not, but not a subpartition level,.
Thanks in advanceHello
I'm afraid that it is not possible to specify level subpartition for the moment.
I connected an improvement on that request.
Please report this problem,
David
