way to delete my subpartitions by keeping my datas, and keep it into my partitions. In fact, i want to remove my subpartitions, and keep my table partitionning. I already remove my subpartition template, but i don't want to do an insert as select on a new table wich will be partitionned (without subpartitions). ALTER TABLE myTable SET SUBPARTITION TEMPLATE ();

I've a table in data warehouse production with data which is partitioned by RANGE, sub-partitioned by HASH.Later we realized that subpartitioned are not needed as volume is less.
I tried below approah in DEV DB:
1. create table ABC_BAK as select * from ABC;
2. dbms_metadata.get_ddl('TABLE','ABC')
3. Removed the subpartitions details from the output of step 2 and prepared the script of create table without subpartitions
4. Drop table ABC
5. Create table ABC from script step 3.
6. Insert into ABC select * from ABC_BAK
7. Drop table ABC_BAK
I created table Rang pertitionned, and List subpartitionned. My table is Interval partitionning. My subpartition is template based as is :
PARTITION BY RANGE ( DINFOIDENTITE )
INTERVAL ( (NUMTOYMINTERVAL(1,'MONTH')) )
SUBPARTITION BY LIST ( AVANT_DERNIER_MATCLE )
[Code]....
i would have the same repartition with 10 differents tablespaces, one for each subpartition.
I search on Oracle documentation this morning, but the only thing i've found is that this option is possible with the STORE IN clause, but only for HASH partitionning.
Is there a way to specify STORAGE clause with a template for my indexes ?
Requirement of merging two schema's into one. I have a client in two diffrent location . intially we setup the application with two diffrent instances of database for them for a smooth opration as they were not having any connectivity between the branches. Now they are moving their both branches together as one organisation. My application database table structure is same in both places.

Here's the original table:
id subid text
-- ----- ----
1 1 red
1 2 blue
1 3 green
2 1 yellow
2 2 black
2 3 orange
result should be:
id text
-- ----
1 red,blue,green
2 yellow,black,orange
SQL to Create and populate the table:
CREATE TABLE testStringJoin(ID number, subid number,text varchar2(50));
INSERT INTO testStringJoin values(1,1,'red');
INSERT INTO testStringJoin values(1,2,'blue');
INSERT INTO testStringJoin values(1,3,'green');
INSERT INTO testStringJoin values(2,1,'yellow');
INSERT INTO testStringJoin values(2,2,'black');
INSERT INTO testStringJoin values(2,3,'orange');

when matched then update...
when not matched then insert all.
I have a table structure as follows
Student(Id,First_Name, Last_Name, email, Contact, Address1,Address2,City,Edit_Date,Create_Date,Archived)
Now if there is more than one row with same email the one with the latest edit date should be updated with missing fields by using same field value other rows (if the field is present in more than one row, the one with the next latest edit date is to be considered) and the archived status of all rows with same email except this master row must be set to 1.
The Create_Date must be set to the minimum of all the create_date values of rows with same email value The create table would be as follows:
CREATE TABLE student(Id NUMBER PRIMARY KEY,first_name VARCHAR2(30) NOT NULL,last_name VARCHAR2(30) NOT NULL,email VARCHAR2(30) NOT NULL,contact NUMBER,adress1 VARCHAR(30),adress2 VARCHAR(30),city VARCHAR(30),edit_date DATE,create_date DATE,archived CHAR(1))
Sample insert statements would be: insert into student values

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.
Can i alter the table to create partition on non partition table, i have tried and could not create it. Do we have some other means to do it as this is the live table and cannot drop them else will lose the data.

This table is being loaded daily with lots of data. relation between DSET_COB_DT to DSET_UID is 1 to many. meaning, for a given date DSET_COB_DT = NOV 27,2012 there will be many DSET_UID=1,2,3,4

NOV-27-2012 3 CB DA
NOV-27-2012 4 BZ CE
I have the above rows in the table such that all above rows are in one partition for nov-27-2012 and each row is in it's own sub-partition.
In order to gather statistics at the sub-partition level as soon as sub-partition is loaded with the data ( i will come to know when the sub-paritition is loaded with data for the day by some other means.) , i need to know the sub-partition name.
how to know what is the sub-parition name when all i know is DSET_COB_DT=NOV-27-2012 and DSET_UID=1.
when i know the sub-partition name, i can pass the sub-partition name to Gather Statistics procedure.
I am a new Oracle DBA that has been tasked with creating some single node databases for our programmers to connect to. I have never built a database, only upgraded. I will be using a Dell 610 with 10.2.0.4 software. I have been reading the install guides but cannot find a definitive answer for how to create the raw partitions. I have a SAN that I can utilize and my current db is set up with RAID 6 like so:
Disk 2 300 GB 1 Extended 300 GB and 5 logical, 100MB, 30 MB, 100 GB, 100 GB, 100 GB
Disk 3 100GB 1 Extended 100 GB and 3 logical 100 MB, 30 MB, 100 GB
why the old DBA partitioned this way? I am not good with storage and know that I need to understand before I build new databases so I do not duplicate something that is wrong. I was reading articles that recommend SAME but would not know how to do that on the SAN.
I will be using data pump to export the database and import to the new server. I was looking at using transportable tablespaces to do this. Would you recommend that from the cluster to the standalone?
